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 unscathedshow more

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 point (sort of like a fulcrum on a seesaw), it happens to be near where the sinking/ driest air is. If conditions are right we may see them pivot, or if one’s stronger (Bermuda hurricane) its force will sling shot the weaker one around it. Still not clear to what degree the Fujiwhara effect will be in effect, but it ought to be interesting! BTW Sakuhei Fujiwhara was the Japanese meteorologist who first observed the phenomenon. #hurricane WFLA NEWS #Humberto #Imeldashow more

I zoomed in and slowed down the actual confrontation... on this video down x4, and also messed with the contrast and lighting to try and clear it up. The original whole clip of this slowed version is just under :07 seconds. It’s clear he was not getting jumped, and as soon as Austin touched him Karmelo stabbed him almost simultaneously.show more
