Hurricane Lee just passed by Bermuda here just 3 days ago and practically wiped out at least one of our beaches. You're really quick with your videos. I really gotta commend your speed and timeliness
I’ve always wanted to go there
Like, completely? No more beach, no sand or anything left? Just a ridge between land and ocean now?
@@thalmoragent9344 Where there was once a sandy beach, there's nothing but a rocky coastline. It's happened before, so i'm pretty sure the sand will be fully back in about 6 months, but it was an insane amount of sand washed out over the course of about 2-3 days
😎😎😎😎😎😎😎😎😱😱😱😱😱😱😱😱😱😱😱😱
Lol get rekt
Hurricane Lee was 10 days ago. Did you put this video together in just 10 days??? So thorough and well-researched. That's incredible skill and dedication 💪
stef is a very resourceful little utuber with the sexiest voice/accent :)
Well before the video even starts the thumbnail pic is wrong so the research wasn't THAT good.
@@filonin2thanks tom
what do you mean it just hit Maine yesterday
Just keep in mind that well put together and presented doesn't necessarily mean well researched. The race to be first will undoubtedly include mistakes and omit information.
I give props to the visuals here (especially the weather globe). you guys are getting better and better
Heard so much about this at the time. Then this week I heard very little about Hurricane Otis, but then I saw that it intensified from a tropical storm to a Category 5 in TWELVE HOURS
It’s wild that this video went out of date just a couple weeks after it’s post.
like i literally knew NOTHING about otis, nobody talked about it
That's wild
really? Otis was always mentioned on the news for me.
1991 I watched the perfect storm from my house right on the seawall, I'd never seen the ocean like that, the waves were crashing over the seawall onto the deck and high tide was still 3 hours away, it was mesmerizing, then the waves started to crash on the house, dark green seawater running down the windows, but then s wave brought a boulder through the sliding glass doors, time to go, but the roads were flooded on both sides, I backed the car up as far away from the house as I could, the next 6 hours we watched the house get swept out to sea, leaving only the foundation. Waves crashing on the telephone pole wires, blue sparks running up and down the line. Marshfield, Mass. 1991.
Sounds amazing
Coooool
That's a terrifying traumatic experience. 😮😮😮😮you have the right attitude towards life nevertheless:)
That's why you never stay when you are on the beach
Lee's rapid intensification was a relatively curious case, as it had a very favorable environment for strengthening, but also wind shear on the south prohibiting rapid development. So Lee was actually very mature in structure when it reached C1 strength, and didn't need to do much to intensify once shear subsided.
If the wind shear wasn't there then it would've been a 185 to 195 mph storm wich is xrazy to think about... the official hurricane center prediction was 185mph but there were models that showed 210+ mph
Maybe they nuked it lol
Guys seriously, if you appreciate the content you need to be liking and sharing this everywhere. Lack of engagement is going to hurt this channel in the algorithm. We can’t let this channel die out because most people want to watch celebrity gossip and shopping hauls

Opening videos with alarmism doesn't help.
Opening the video with a truthful explanation using measured data is not alarmism@@Racketeerof89
Selective info alert: Yes, 2020 had 31 storms and 14 hurricanes, and this year we're at 15 storms and 6 hurricanes already. But last year only had a total of 14 storms and 8 hurricanes, while 2019 had 18 storms and 6 hurricanes. It's not like storm numbers are consistently high.
Yes there are a bunch of factors at play which affect how many and where these storms form. Most notably the impact of wind sheer as well as the weather conditions like cloud cover dust abundance and sea surface temperature in the typical zones of formation. Both years listed had a number of factors at play restricting the formation of tropical cyclones off the coast of Africa but what does stand out here is that these years where storm building activity off the coast of Africa was suppressed we have seen the formation of tropical cyclones well outside the typical zone of formation particularly within or near the Gulf of Mexico and Caribbean. There is some work looking to extend back our knowledge of storms with historical records going back to the area of colonialism and the imperial conquest of the Americas coupled with analyzing sediment samples to look for storm surge impacts to gauge the strength of cyclones that seems to support the idea that the lack of weaker storms to drain building up heat in the ocean can itself allow storms that do manage to form to have the fuel to become larger and stronger than typical. Basically like everything else its complicated when you did into the details.
@@Dragrath1 tropical cyclone regularly form in the Caribbean and gulf of Mexico even NHC has it on their website
If only you waited until 14:30 where she goes over the number of storms not increasing, you wouldn't be subject to a selective info alert yourself
Hurricane Lee made landfall in Nova Scotia the day before this video, It was a direct hit on the town I live in. No matter how many hurricanes I've lived through, it's always eerie when you go through the eye of the storm
I live in Mozambique now and had my house torn once and the whole village turned upside down twice in the last 7 years. I don’t even want to imagine how Madagascar is doing
I'm in NZ in Napier we had a cyclone hit in February had enough rain to flood entire suburbs house high they're not to be messed with
Wow. Is that actual satellite footage of Typhoon Tip in 1979? Looks so modern. I didn't know we had that clarity back then.
For real
They probably cleaned up the footage and upscaled it for the vid but still
I forget the year now but it was many many years ago, probably more then you think. That they could zoom down onto a pack of cigarettes sitting on top of the hood of a car within the Soviet Union, and know what kind.
@@gunrunnerak4774 I've heard that some 20 years ago. Still the 1979 weather satellite must be in geostationary orbit which is a very high orbit and that footage is pretty wild
Another thing worth mentioning is how these storms are also migrating further north with places such as Scandinavia getting hit by powerful storms more frequently and with greater power.
yes they storms but NOT cyclone,hurricane or anything else.
@@jmdds they are cyclones, specifically extratropical cyclones
@@i_am_a_toast_of_frenchthey are NOT cyclones but extratropical cyclones
Always surprises me when Hurricane Michael isn’t mentioned in videos about Hurricanes. The first Cat 5 to hit the contiguous US in over 20 years and the first Cat 5 in recorded history to hit the panhandle.
I feel like this video is focused mostly on the Pacific Basin. I noticed many mistakes in data that can only be explained if the film creator was only discussing the Pacific Basin in certain sections. Just an observation 🤔
It is the first... we all know it won't be the last. We got Ian on the Gulf Coast last year, now Idalia, both were weaker than a cat 5 on landfall, but we're still getting big storms. Why is it almost always the 'I' storms? 🥲
@@Savage.-_.Gamer1 The answer is development time. (I'm a meteorology student, so not a professional, but someone with a good chunk of knowledge) In a typical Atlantic Hurricane season, the 'I' storms will typically form in late August through September or 'Peak Season' where seas surface temperatures are at their highest, aiding development. Examples would be Ian (2022) from September 23-30, Irma (2017) August 30th-September 12, and Ike (2008) September 1-14. I hope this helped!
@@rowansalem5443 yeah, also Ivan(2004) September 2- Sep 24
@@rowansalem5443 Thanks for your reply! And also, since we're Almost at the end of the list, I wonder if we'll see anything like 2020 Atlantic H.S. again, with 30+ named storms... not impossible...
I really like your weather related science videos and would like to see more focus on weather related events. Thanks.
You must have had this ready and just been waiting on the right time to drop a video. Great job on the information given.
I’m gonna be transparent here, the amount of storms we’ve been receiving has not been abnormal for the last 20 years. Back when we had hurricane katrina we literally went through the entire Greek alphabet and that was in the 2000s. What we have to pay closer attention to is the speed of intensity and not the amount of storms as that has a lot to do with not just how hot the ocean is but different wind patterns impacting the storms stability.
I wonder if people would take hurricanes and typhoons more seriously if we called them MegaKiller5000 instead of cute names like Amy and Freddy
It would be more accurate for sure . The cute names are given in alphabetical order to count them,, but what if we reach the last letter , and that there is more Hurricanes coming After ?
True Bhola means innocent to think it was the name for deadliest cyclone
The original idea of the names (according to the met office) was that more people take note of named storms and it makes it easier to communicate with broadcast media .
In Japan they just get a number
A study showed that hurricanes with female names are actually deadlier than ones with male names because people don't take them as seriously and it leads to a higher loss of life.
this still doesn't change the fact that there are 49million kangaroos in Australia and 3.5million people in Uruguay which means if the kangaroos were to invade Uruguay, each person will have to fight 14 kangaroos 😤
I’ll take up the challenge
oh god there’s more kangaroos in Australia then people in Australia..
In the midst of the confusion, Brazil can take advantage and take Uruguay again and reconstitute Cisplatina
This episode is exactly what I wanted! :D
Drove over to Sagamore Beach in Bourne, MA Friday night to check it out. It was an impressive sight, super strong winds, and very large waves for the area.
I was in Wellfleet when it passed and it was basically like a moderate Northeaster. 🫣
I used to bike down there before i moved to Florida
Thankfully Lee calmed down before walking through my backyard, never lost power :D
With so many recent storms over the Atlantic, I have been wondering about them coming together and how they would behave. So thank you for doing this video.
Oh yes a real science video this is like twice as good as a real engineering video
Absolute cap, it is the other way around.
@@AcrabatXno.. Without science, there'd be no engineering.. Be grateful

Y'all adorable
0:34: 🌀 Hurricane Lee rapidly intensified from a category 1 to a category 5 storm in just 24 hours, becoming the third fastest intensifying Atlantic hurricane on record. 4:12: 💨 Tropical cyclones weaken and slow down when they travel over land or colder water, but can still cause damage and produce rainfall and strong winds. 8:31: 🌪 The interaction of tropical storms can lead to unpredictable paths and behavior, with the potential for record-breaking intensity. 12:33: 🌪 Satellite data shows that the intensity of tropical Cyclones has been increasing due to global warming, but there hasn't been a significant increase in their frequency. 16:01: 🌩 Scientists are working on better forecasts to predict the characteristics and damages of storms, improving warning systems and evacuation planning. Recap by Tammy AI
Tammy AI is shorter than the average, so yeah.
It doesn't know where the north Atlantic is
Pre 1940 who was monitoring from the sky’s and satellite such storms for intensifying records. I am very sure the 1935 185 MPH sustained winds 892Mb cat five storm smashed any records that Lee set.
what is this
12:33 and yet 6 of 7 strongest storms in history are over 40 years ago or more. Something tells me the Satellite Data might be missing something
We had a fujiwara effect last spring in the Bay Area and a eye wall formed. I remember being being in Millbrae looking up and seeing walls of clouds.
This was wonderfully put together!
For some reason to me, hugo has always stood in my mind as a unique storm. Most likely because a year or so after it happened, I took a trip from my home near orlando, fl to visit relatives in charlotte, nc. As such, the trip was just a run up i-95. But even that year or so later, the devastation was still on full display. As you could see the corridor where the strong winds were by all the trees flattened to the ground in one direction. That said, I swear at one point it had 3 eyes, but I see no record mentioning it. And I see nothing in a quick google search about any hurricane with three eyes. I swear there was one once and it made the news. However, like other memories, I must have confused it with a dream or something. Two eyes have happened, but a triple eye just has google kicking back about cat 3 storms.
Smoke another one guy
observed and reported triple eyewalls: typhoon june 1975 hurricane juliette 2001 hurricane iris 2001
Hurricanes are not necessarily "worst" or bad. They actually serve an important purpose. They draw heat out of the oceans and cool it and cause the upwelling of cooler bottom currents to further cool ocean waters.
Hurricane Otis intensified to a Category 5 and had an intensification record of 110 miles mph.
Very good presentation. Thank you.
Could counter-rotating storms pair up? Would that make them more stable? Move faster? Stronger winds? Cancel out?
I also want to know
Storm rotation direction is controlled by the Coriolis effect which means this scenario is impossible at least in the case of two low pressure systems or even high pressure systems. That said if you were to be able to allow such storms to meet their net angular momentums would largely cancel out. The closest real example to this is the storms of Jupiter which can be defined into more "normal" low pressure cyclones and massive high pressure systems fueled by upwelling heat which on Jupiter can become visible if they become large and deep enough to dredge up deeper layers of the planet most notably seen with the great red spot.
@@Dragrath1 So it wouldn't be like how pair of counter-rotating whirlpools behave on the surface of water, or the sorta higher-dimensional analog, vortex rings?
I remember getting snow during hurricane Sandy and I’m in West Michigan. The outer bands ran into a cold front over us which caused snow for a few hours before it drifted back east. Nothing stuck, but seeing the outer band reach THIS FAR was amazing.
this is a nice educational video Fusion of storm
Has anybody ever heard of the fujiwara affect it's when two tropical systems interact with one other the larger stronger system is the one that dominates
Ten seconds in, the tornado siren in my town went off. It's just a test, but how ominous....
Amazing watch! You are appreciated
I'd like to know if Brilliant happen to do a course on how to skillfully merge your video topics into adverts for sponsorship ads.... because clearly Steph has got it down to a fine art 🤣
I wrote a MSc thesis about North Atlantic Sea Surface Temps and the formation and maturation of hurricanes. Like your report, I couldn't detect an increase in frequency. But I was not familiar with the two metrics - Accumulated Cyclone Energy and Power Dissipation Index - which you show follows SST in North Atlantic. Do you know whether these metrics have been used for tropical cyclones elsewhere on the globe and if so, do they show similar influence?
These metrics are used worldwide... they were developed by the World Meteorology Organization, the international weather group that oversees weather forecasting and data collection on a global scale. Check out their website.
accumulated cyclone energy is the sum of (Vwind)^2 for every six hours times 10^-4 while power dissipation index is to the 3rd power power dissipation index is pretty uncommon to see used while ace has been the standard since 2000 for the nhc/noaa
Great video!
So my take away from this is: less small to medium size tropical storms! Dope! Keep up the good work. The world needs more good news
Is the only tropical cyclone nightmare in your mind the 2020 Central Vietnam floods?
i live in milwaukee and i remember it being more windy than usual during sandy. i was living in appleton at the time. wisconsin can be windy and so can the lakes, but that wind was WINDY.
if hurricanes can combine, can they "cancel" each other as well?
editing is fire
Two cyclones colliding are not unlike two galaxies merging in space, except for the time involved, like days vs billions of years. Perhaps we should embrace the event as a bigger story in our cosmos.
Look at the number of Cat 5 hurricanes that number has gone up significantly over the past 25 years. Cat 5 were rare things 1 or 2 every 5 or 6 years now its 1 or 2 every year. The frequency has gone up and so has their power as now every storm breaks a new record. Mathew, Irma, Dorian and Ian just to name a recent few that set new records.
Yes it's called mother nature it's unpredictable
@@truckercowboyed2638See that's the whole thing. Actually it is "Predictable" and weather and Climate 2 different things.
Could you do a look at floods and the storms that cause them with a similar review and projection? Thanks most informative
Needs to be separated into rainfall based flooding vs storm surge. Usually what is most lethal is the surge, where wind speed, total storm movement, and nature of the seabed below all matter. However, there are some exceptions. One of the really lethal us storms was weak by wind speed standards, but stalled over an area in Texas prone to flooding and dumped a ridiculous volume of rainfall. Either way, such depth of water plus wind speed is way more than most structures can withstand. Only thing worse would be direct f5 tornado hit without a basement shelter. F5 wind speeds are insane, much faster than functional max intensity hurricane winds.
@@TheMelnTeam I am interested in recent inland flooding in Australia
Im living in the Philippines, a typhoon prone country. (cyclone for Indian ocean, Hurricane for Atlantic) Sometimes storms combine and we dont have classes for almost a week 😂😂 Some people call Philippines "typhoon barrier" country.
I would argue against the frequency of storms. Frequency of BIG storms increase, for sure. But because the air is getting warmer, it holds a lot more moisture in the atmosphere. This in effect means that raincloud have a harder time precipitating as they need a lot more moisture before they start falling. So severe storms will come more often, but they are fairly rare before so on a whole, you will see less number of storms overall with a hotter climate but those that do forms will likely be stronger on average. At least that will be the case at first. If we warm the climate enough, that might change entirely.
this is amazing! as huge weather nerd, I love this!
He's wrong. Dude 65% of this video is false trust me im generally not kidding bro
aww@@PizzaexpresspumpkinXP
@@PizzaexpresspumpkinXPliterally said trust me bro are you going to explain what they got wrong
@@theironqueen2386 the only thing they got wrong was creating them, everything else those is cool, cause heat only produces heatwaves and forest fires and heat is just an abstract of nature, meaning its just a common thing to happen, but does not revolve anywhere around cyclones.
@@PizzaexpresspumpkinXP I'm sorry to tell you but this is a quote from the Australian institute for marine science www.aims.gov.au Cyclones develop over warm waters in the tropical regions of the oceans where areas of very low pressure are created by air being heated by the sun. This causes the air to rise very rapidly and becomes saturated with moisture that condenses into large thunderclouds. So heat as quite a lot to do with it but just a misconception
I hope you make videos on wildfires, tsunamis and earthquakes too
Excellent research, brilliantly compiled work, great visuals and elocution, great job guys!
Could you include ferhenheit along with celcius for us Americans? Also mph and miles...
Good idea. Furlongs, roods, bushels & firkins should be included for the upper-class English like me too.
There are more named storms because they changed the criteria for what allows storms to get a name. Not saying that there haven't been more storms, but that definitely adds nuance and makes it more difficult to compare. You can't just make a blanket statement like that
that's the nature of the cyclone phase space
The costliest hurricane ever (Katrina) actually formed, intensified and peaked outside of the tropics, weakening to an C4 and then hitting land as C3.
That was largely due to the location. New Orleans is below sea level and the levies didn't hold
You have the most beautiful voice I have ever heard.
My Prayers Go Out To Everyone Who Has Gone Through A Hurricane ❤❤❤❤
Cool! Love your KZhead channel!
Heavy Precipitation From Cloud Burts. No Thunder or Lightning Windspeeds about 60kms per hour, almost 5 minutes past.
Excellent information. Hurricane Sandy was extremely nasty. No one talks about Florence, though, and that one nearly washed parts of North and South Carolina out to sea.
Did you guys know hurricane Michael there was a peak wind gust of 218 mph it stayed at Category 3 all the way up in the Albany Georgia and also hurricane Michael went through Rapid intensification and the strongest windmass was 24 miles in diameter 20 + inches of rain and also over 25 ft of storm surge
Hurricane Michael really seems like the forgotten Hurricane. Surprising to hardly hear it mentioned
I live an hour west of where Hurricane Michael came ashore. The only people who seem to remember and/or talk about Michael are those in the Florida Panhandle or Southern Georgia (basically only those effected by the hurricane).
@@poetlygaming1566 I think you're right
Wow
13:25 What happened in that 2006-2015ish zone? i know the graph before showed lesser storms as well, but why? what happened over those years. why the anomaly? or would a longer time period data set show more anomalies?
A huge constant influx of Saharan dust across the Atlantic suppressed hurricane development. But, the downside is the water continued to heat.
I think what you may be wondering about is El Niño-Southern Oscillation, or ENSO. During el nino years, the atlantic basin tends to be less active with hurricanes, and during la nina years, it tends to be more active. This is a natural cycle that effects the climate and sea surface temperatures in various parts of the tropics. en.wikipedia.org/wiki/El_Ni%C3%B1o%E2%80%93Southern_Oscillation#On_hurricanes
This is a good video for my meteorology class for pre-service science educator.
8:09 Actually, Hinnamnor and Noru were both the Strongest Storms in 2022. If you don't know: Noru had wind speeds about 165mph tied to Hinnamnor that was also 165mph forming also on the same month. What"s even crazier, Noru had an "Extreme Intensification" that turned into a Tropical Storm to a Deadly Category 5 Typhoon in just 12 HOURS. After that, it caused it to trigger a Signal No. 5 warning in many areas of the Philippines. The Signal No.5 warning was used after 7 YEARS since Typhoon Haima (2016) caused a Signal No. 5 warning.
I can recall Parma in the philippines. It was just nonstop rain for a handful of weeks!
So as the sea temperatures increase, the storms become more numerous and erratic. And this could happen tomorrow. No need to worry about asteroids and volcanoes.
Yes, Lee intensified very quickly, but is not the first to do so. Look up Typhoon Rai/Odette from 2021. (160km / 100 miles increased wind speed)
She said third
It's not just the heat... it's the humidity 😂
Realize they collide like black holes do, they exchange angular momentum and orbit around a point that becomes the new eye
Ya know like two spiral galaxies colliding
Hurricane Saola hit Hong Kong on September 1-2 and Saola was strong 230km/h winds speeds. The observatory issued T10 Hurricane signal and it was just 30km (19miles) away from Hong kong .and on September 7 we encountered the strongest rain storm of all time in Hong kong 600mm and it happened for 16 hours
A hurricane during hurricane season, oh my, has this ever happened before, oh my
Idk why, but when you said "24% wetter" I kept hearing "24% weather" really fast lol
Instant stroms... sharknado is coming
Now this is what it’s like When STORMS COLLIIIIIIIIIIIIIIIIDE!!! - Weatherman 5000
Category 1 and 2 hurricanes have seen no change,category 3 a slight increase, 4 and 5 a clear decrease so overall there is no clear increase or decrease for the last 40 years.
something that comes to mind within the first few minutes of beggining this video, is hurricane Sandy (not 100% which storm it was exactly) was dying down in the gulf, and there were two "blips" in the eye of the storm on satiilite radar, and suddenly the storm increased in strength over the next several hours, and wound up going up the east coast.
Beginning*
Cuz this is what it's like when storms collide!
2000 km is the distance from rome in italy to oslo in norway and from madrid in spain to budapest in hungary.
At English parties English blokes discuss things like that non stop.
Check out the data when you measure the growth rate of a human from age -9months to age 10. It's crazy when you plot it out into a computer model and then run it to see how big humans are in their 70's.
Interesting, but completely off-topic since this is a video about tropical cyclones rather than mammalian maturation rates.
@@kirbyjoe7484 oh no I was referring to the absurdly short time span that they get these "models" from to talk about doom and gloom. It is such a short time span that it would be like taking a snapshot of a human's data and declaring the human was dead because you don't have the next second's worth of data.
I spend my days anxiously awaiting the next real science video 😂😂
7:29 'The lowest sea pressure ever recorded' ? That would be atmospheric pressure at sea level.
Its crazy how they came out just before the record setting storm in Hong Kong going on right now
NASA chief: personally, I'd say yeah, the universe seems too big to not host other forms of life... WION: NASA chief confirms aliens exist!!!
How did the one in the Pacific form this year? I always saw that we don't get hurricanes in Cali cuz the water is too cold.
Plenty form in the same area that one did but they usually go west out into the Pacific. The large-scale patterns of high and low pressure at the time were just right for it to go north towards CA instead. The cold waters along the coast did still cause it to weaken as it approached though.
May be it would be time for US building codes to take cyclone winds and rain into account? The current stick and cardboard box construction method and power lines above ground does no longer cut the mustard with the continuous heavy storms. In Europe we also can get storms with wind speeds around 120 to 160 kph. But normally these winds only take off the roofs of some houses, but they do not destroy power infrastructure yo the degree seen in the US.
Umm you also do not have the size of infrastructure we do nor the population size that we do. We're more spread out to
fun fact: traffic lights in florida often have large rigid frames to withstand strong winds and all emergency shelters in miami are rated for 200 mph winds after hurricane andrew also trees tend to fall down if you haven't had a storm in a long time
Hurricane Jova literally a day before Lee did its rapid intensification phase was faster than Lee in the East Pacific
U should do an anatomy vid on sea otters
I love your videos 😊
3:07 This is not true. The storm becomes a tropical cyclone once it has a closed isobar, which can happen as low as 40kmh (25mph). 118kmh (74mph) is when it becomes a hurricane, but tropical storms and depressions of weaker winds are also tropical cyclones
it requires more than a closed isobar, it needs well defined circulation and 100% of its energy has to be from warm air/water
Wow great information. I didn't know about the longest lived longest traveled hurricane that's insane. I was shocked it hi hit Africa. Great info.
Top notch as always! Thank you ☺️
I saw the Amphan cyclone in May 2020. I am from West Bengal, India. The wind speeds reached 133Km/h in Kolkata.
When 2 storms like eachother vary vary much...
0:35 Hurricane lee Rapidly intensify 4:12 Tropical cyclones 8:15 The intense of storm 12:58 satellite data 16:05 weather Forecast
"Two cyclones merging into a mega cyclone" is just patently false and impossible. Think about it -- the two storms, no matter from what direction they approach each other, will *always* be rotating in the opposite direction. the point where they touch would always be severely windsheared, breaking the structure of both storms before they merge.
So interesting, thanks!
we need major hurricanes on the west coast of california. we are bored here
Well now there’s 15 storms so yeah we might get close to 20 by the end of September and 25 or more by the end of the year
There was a hurricane in texas one time that made landfall, weaken, and then restrengthened when it was miles in land. I was classified as that years later.
I'm going to need a bigger umbrella.
nice vids bro
