Y'all see this swirl over the Mediterranean passing south of Benghazi? That's not a hurricane – it's a Medicane. Yes, that's a real term. The word is a portmanteau combining "Mediterranean" and "hurricane." The Mediterranean is too small to support barotropic (tropical cyclones) the scale of conventional hurricanes AND is too far north to support a truly tropical cyclone anyway. Moreover, water temperatures are too cool. (Most tropical cyclones exist over sea surface temperatures of 78 degrees or warmer; the current water temperature off the coast of Libya is about 63 degrees.) Medicanes can and occasionally do reach hurricane strength. The strongest on record was Medicane Ianos, which impacted Greece between September 17-18, 2020. It briefly became the equivalent of a tiny Category 2 hurricane with winds of 95 mph. On rare occasions, a nontropical low can meander over the Mediterranean, and a storm can form that takes on some tropical characteristics. Unlike nontropical cyclones, which are common at the mid-latitudes, medicanes feature a warm core. That requires warm sea surface temperatures. A 2016 study found that medicanes are likely to become significantly stronger by the end of the century in response to warming sea surface temperatures. Tthe researchers found a likelihood for "a higher number of moderate and violent medicanes.” Since 1980, Mediterranean sea surface temperatures have increased between 1 and 2 degrees.

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

On May 20, 2013, 13 years ago, this incredibly sobering audio was being blast across TV and radio stations across McClain, Oklahoma and Cleveland Counties, Oklahoma. This was the dire tornado emergency issued for Moore as an EF5 bore down on the same place the tornado emergency was invented in 1999.

LOOK AT THESE! You've probably never heard of "mesovortices," but the eyes of major/intensifying hurricanes, like Category 5 Melissa, actually contain addition, smaller whirls a few miles across. Mesovortices are a few miles across; they form as a way to balance an extreme discontinuity in angular momentum. In the buzzsaw-like eyewall – that ring of winds spiraling around the eye – there's an incredible amount of extreme wind and "angular momentum." But in the eye, there's hardly any – the air is calm. That means the eyewall "chafes" against the calm eye. Since the atmosphere is a fluid, that chafing pinches off into eddies and vortices. Think about when you're kayaking or canoeing through a pond. You might notice a few whirlpools shedding off your oar as the moving oar sweeps through the stationary water. A similar premise exists here. In this case, the atmosphere handles the transition from the eyewall to the eye by having some of the fluid "curl back" on itself, forming 4, 5 to 6 smaller "mesovortices." This eye exhibited a "wavenumber 5" pattern, meaning there were five mesovortices. The mesovortices often contort the inner edge of the eyewall into a wonky "sawtooth" pattern. That means that, if you stand right near the interface, you'd have about 5 minutes of "in... out... in... out" where, despite being basically in the eye, ebbs of the eyewall could still swing through and bring you a sudden, extreme gust. Welcome to the magic of fluid dynamics in the atmosphere.

A few could be rotating supercells. يقع مركز الضغط المنخفض بالقرب من الأردن؛ وفي الجهة الشرقية، يُسهم تدفقٌ جنوبيٌ رطب في تشكّل العواصف فوق شبه الجزيرة العربية، وقد يكون بعضها عبارة عن خلايا عاصفية فائقة ودوارة.

Where have all the EF-5 tornadoes gone? It been nearly 12 years since the last EF-5 touched down in Moore, Oklahoma. Plenty of devastating tornadoes have struck since, but none have received the highest-possible rating. What makes EF-5s so elusive? Weatherman Will explains.🌪️

BREAKING: Kīlauea’s is erupting RIGHT NOW! This is the 34th eruption from the Halemaʻumaʻu crater; lava fountains are reaching 330 feet high – taller than a football field! The activity began with smaller gas-driven spurts around 12:53 a.m. HST, but has since intensified. The lava fountains are now leaning northeast. All activity is contained in the park. Northeast winds are pushing volcanic gas and material, like ash and Pele's hair (stands of volcanic gas) up to 20 miles to the southwest. That could affect communities like Pahala and Nāʻālehu; don't turn your windshield wipers on, as small glass filaments scraped against your glass windshield could cause damage. The small glass particulates and ash could cause skin and eye irritation too. The volcano is also pumping out up to 50,000 tons of sulfur dioxide a day. That could create vog (volcanic smog) and result in additional respiratory issues downwind. We don't expect lava flows to be an issue, and lava should remain in the caldera. The December 2024 eruption was a short one, lasting about a day.
