Fujiwhara?? When two hurricanes interact, they can sometimes pivot around one another. Next week there will likely be 2 tropical cyclones (perhaps 2 hurricanes) offshore. If they are strong enough, and are close enough, a #Fujiwhara may happen. Here’s how it works. Between the 2 storms is a pivot...

An incredibly rare situation as Imelda and Humberto *merge* in the Northwest Atlantic – two active hurricanes combining into one larger, more powerful hurricane! On Tuesday morning, Humberto and Imelda were separated by just 476.4 miles – second place to the record for closest Atlantic hurricanes. (Two hurricanes in 1853 made it to within 428 miles of one another). When hurricanes pass within 800 or 900 miles of each other, they interact in a rare dance called the "Fujiwhara." Basically, they dance around each other. Humberto was initially a much stronger hurricane. Over the weekend, it yanked Imelda eastward. That technically means that a hurricane helped spare the U.S. a strike from another hurricane! How ironic and bizarre is that!? But now Imelda is the stronger hurricane. It has winds of 90 mph, and Humberto's winds are at 80 mph. In the next couple days, Imelda will ingest Humberto's vorticity, or spin, and the two low pressure systems will fold into one larger, more powerful low over the northwest Atlantic. It will probably retain hurricane-strength winds, and it's likely the Hurricane Center will allow Imelda to keep its name! The Fujiwhara effect has happened before – iconic examples of the Fujiwhara dance were observed with Odette and Seroja in the Indian Ocean in 2021, or Hilary and Irwin in the eastern Pacific in 2017. The Fujiwhara effect happens with atmospheric vortices of all scales. For nontropical (midlatitude) cyclones to be influenced by each other’s presence and interact, they need to be within about 1,500 to 2,000 miles. Their interaction becomes more intense once they’re within about 1,200 miles. Hurricanes are smaller, so that threshold is smaller. But even tornadoes orbit one another in Fujiwhara-like interactions! When a storm spawns multiple tornadoes simultaneously, the twisters tend to swirl around each other in a counterclockwise fashion. In fact, that happens regularly with what’s called cyclical tornadogenesis, or the process by which rotating supercells produce successive tornadoes. A dying twister is tugged ahead of its successor, then swirled left (north) into the rain and hail where it’s stretched into oblivion. As its predecessor dissipates, the new, stout tornado matures and begins tracing its large counterclockwise path. These handoffs can happen every 15 or 20 minutes in powerhouse thunderstorms. The Fujiwhara effect can even manifest within individual tornadoes. Most tornadoes contain smaller whirlwinds called subvortices. They last a few seconds each, and whip around the parent funnel. Individual subvortices can locally enhance the parent tornado’s wind field, leading to narrow swaths of extreme destruction. That’s why one home might be obliterated while a neighboring structure escapes unscathed

Complete satellite loop of the closest Fujiwhara Effect between two Atlantic Hurricanes ever recorded in the satellite era. The only other known Hurricane couple that was closer than Humberto and Imelda this year was a pair of storms in 1853.

Some rare and remarkable processes are taking place this week, that we are not likely to observe for a long time! These 2 Atlantic hurricanes are closer than any since at least the 1960s. They are now connected - in each other’s orbit, pivoting. Stop 1. Notice the calm area at the pivot point between the two storms caused by sinking air. Stop 2. #Humberto dissipates and #Imelda cannibalizes its moisture and energy, passes over #Bermuda, grows, then heads out to sea. (2 hurricanes can NOT merge both as hurricanes. One must die or transition extra tropical first) Stop 3. Imelda meets a frontal boundary where it scales the front and is accelerated NE.

This is arguably one of the most complex steering scenarios in recent memory!! Two hurricanes(?), a stalled cut-off upper low, and a deep Greenland cold pool diving south. How all these factors interact with each other is driving the models (and meteorologists lol) up the wall!! Will soon to be #Imelda be pulled into the Carolina coast by the cut-off low as many solutions show? Or will #Hurricane #Humberto drag Imelda gradually out to sea, as Humberto gets dragged north by the large Greenland jet stream trough? Only time will tell, but folks from FL’s northeast coast to the Carolina’s especially should stay weather aware. More obviously Imelda will impact the Bahamas this weekend-early next week and Bermuda needs to watch #Humberto. In all this, a #Fujiwhara pivot is possible! WFLA NEWS

RARE #FUJIWHARA EFFECT? 🌀⚠️ This is *on the table* as the latest #ECMWF suggests. Depending on the interaction between #Humberto and soon-to-be #Imelda, the latter could cause SIGNIFICANT impacts to the Carolinas, including a flood threat. News 5 Cleveland #StormHour Mike's Weather Page

Everyone's all hyped up Fujiwhara-ing tropical cyclones. Let's not forget that each day of tornadoes during the April 25-28, 2011 Superoutbreak was the result of a conga line of shortwaves Fujiwhara-ing around a massive longwave:

Wait for it. Major Hurricane Erin is intense, but soon it will be massive in size. As the storm moves north the wind field will expand, as is typical of hurricanes. Tropical storm force gusts will extend all the way from the beaches of the Eastern Seaboard to Bermuda around 700 miles, with hurricane gusts over 300 miles wide. #erin #hurricane #fyp #HurricaneErin

‼️🇺🇲🇮🇷 "Now is the time for Iran to join us on the path that will finish what we are doing. If they join us — that will be great. If they don't join us — that will also be great. But it will be a completely different path." "They can no longer pose a threat to the stability of the entire region. They must make a deal. If that does not happen, bad things will happen." - Donald Trump

Dear goodness. The cell northwest of Fort Worth is moving southeast. It has two areas of rotation, both of which may be producing tornadoes. It just whipped both circulations westward… a highly deviant motion… AND its mesocyclones MAY be Fujiwhara-ing. Graphic from MyRadar Weather.

A Russian Iskander targeted what Ukrainians claim is a humanitarian aid convoy in the Chernihiv region while the Russian MOD claimed they targeted a UAV launch position. It makes no sense for there to be a humanitarian aid convoy to be on a small dirt road in middle of a field in Chernihiv but it still could be one. It is not known if the people in photo are first responders or the people targeted. Will update if more information come out.

The tiger is a monk. It won't bother you, or be bothered by you. It tries to maintain its composure as much as it can. Even if you are around it, it will most likely be unfazed. And even when a tiger expresses its aggression, it is mock. It's a construct.

Hurricane season starts today. Here’s why we expect it to be a quieter than normal year in the Atlantic. The relatively hotter East Pacific due to a Super El Niño overpowers the near waters of the Atlantic. Rising air, thunderstorms and hurricanes in the East Pacific should subdue the Caribbean with sinking air, wind shear, and less storms. But less storms does not equal no storms. So be prepared as usual. #hurricaneseason #hurricane #science #stem #florida

🇺🇸🇮🇷 Trump: They have suffered a military defeat, and now we will open the Strait with or without them, but it will be open. We are going to open the Strait, as they call it, and I think it will happen fairly quickly, and if not, we will be able to finish it one way or another. Everything is going well. No nuclear weapon, number one. I think it has already been regime change—we never had that as a criteria. No nuclear weapon—that is 99% of it. We have other countries coming up to help with the Strait of Hormuz. We will have that open fairly soon.

Bomb Cyclone Fujiwhara 🌀🌀 Yes, those are real words. Another area of low pressure is rapidly deepening off the Pacific coast, this time spinning around the first “bomb cyclone” to the north to eventually become the stronger system of the two.

The steering forecast for #imelda is complex to say the least. A direct hit of a #hurricane in the Carolina’s remains a real possibilty early week. Thats because a weak upper level low stalls and attempts to capture (soon to be Imelda) as it moves out of the #Bahamas. The key here is speed and it’s what separates the different model solutions. The models that are faster with Imelda show a landfall. But the slower members are just slow enough to allow the influence of #Humberto, and by association, the deep trough/ jet stream over New England, to “tug” Imelda out to sea at the 11th hour. Lots of balls in the air and certainly some fascinating science. Florida appears to be shielded from Direct impacts, but the Bahamas will have a direct hit of a tropical storm or low-end hurricane. Be prepared!

No, your eyes are not deceiving you! Next week's cold blast is going to be “near” historic in #Florida for early November. The models are very aggressive and if they are right we may tie or break records set ~100 years ago. These are wind chills for Tuesday morning BUT it is not out of the question that North FL will see actual low temps near freezing next Tuesday and Wednesday mornings. Fire up the fireplaces! You don't have one? You have a week to get it :)
