At this exact minute in 2013, the immense and erratic El Reno tornado touched down. With winds of up to ~313 MPH in its sub-vortices, it produced some of the most extreme radar velocity imagery of all time.

UPDATE: Category 5 Super Typhoon Ragasa (NandoPH) has just hit a new peak intensity of 180 MPH sustained winds and a minimum central pressure of 905 MBAR. This intensity is approaching the upper limits of what Earth is capable of producing.

The amount of convective available potential energy over the Middle East on Thursday is enough for a textbook hatchery of supercell thunderstorms. Where this unstable mass of nearly 5,000 J/kg of CAPE intersects with the dip in the jet stream will determine the greatest threat area for desert tornadoes (most likely in the UAE, Qatar, and Saudi Arabia) and/or strong marine waterspouts over the Persian Gulf.

BREAKING: Category 5 Hurricane Melissa’s sustained winds are now roaring at 175 MPH, and the air pressure in her searing eye has sunk to 906 MBAR. The storm is starting to take the northern turn towards Jamaica, and if she intensifies any further, she will begin to approach the mathematical limits of how strong a storm can become in this part of the world.

At this time in 2024, the Philippines were in the midst of a 10-DAY span in which they were struck by FOUR consecutive Typhoons. Now this year, the country is reeling from the effects of Kalmaegi (TinoPH) and Fung-wong (UwanPH) both making landfall within the last 5 days.

What an intimidating sight Fung-wong (UwanPH) has become over the Philippine Sea as her winds creep up to 65 mph (100 kph). The sprawling size of this budding West Pacific beast is creating an interesting dichotomy. On the one hand, it’s causing Fung-wong to take longer to organize and thus delaying a potential round of rapid intensification (limiting how strong she can get before striking Luzon). But, on the other hand, her larger radius will affect more people in the Philippines and possibly generate a greater storm surge risk near the location of landfall. Even in this latter scenario, which seems to be increasingly more likely, Fung-wong could still explode to a high-end Category 4 Typhoon. Either way, it’s a serious situation we have developing here tonight.

BREAKING: Category 5 Hurricane Melissa has achieved a new peak intensity of 180 MPH sustained winds and a core pressure of 896 MBAR. She is officially the 5TH MOST INTENSE Atlantic Hurricane in history and is nearing the maximum theoretical strength a storm can reach in this part of the world. Landfall over Jamaica is just hours away.

JUST IN: Providence, Rhode Island has officially measured their most extreme snowstorm in recorded history, with 32.8 in of snowfall and climbing. The previous record was 28.6 in, set during the Blizzard of 1978. Historic radar loop.

The eye of Fung-wong (UwanPH) is really starting to melt through the icy shell of her CDO now. New, towering thunderstorms are rising up within the inner eyewall as well. On microwave imagery, the Typhoon’s cumbersome core structure is still yet to fully solidify. What we could see in the coming hours, especially after the Pacific sun evanesces below the horizon, is for this new burst of core thunderstorms to freeze the eyewall into a more complete and circular ring around the eye. That would likely jumpstart a true phase of rapid intensification right as Fung-wong enters her final approach to Luzon in the Philippines.

Hurricane Melissa, at the moment that she possibly became the strongest Atlantic Hurricane in recorded history, may have had the most extreme detonation of lightning activity ever observed in a storm in this part of the world. Nearly 700 flashes every 60 seconds. What on Earth.

Almost all Major Hurricanes undergo an eyewall replacement cycle. Melissa never did. She sustained CATEGORY 5 status for 35 consecutive hours, the 8TH longest total duration of Cat 5 winds ever documented in an Atlantic Hurricane, and the longest since Hurricane Irma in 2017. Instead of initiating replacement cycles, Melissa underwent eyewall mergers, which caused only short-lived pauses in her intensification and allowed her to incrementally climb to an extreme strength as she slowly writhed towards Jamaica. It is exceptionally rare to see a high-level Hurricane eye remain so perfectly circular and clear for so many days on end.

🧵 33 years ago this morning, NWS Miami captured one of the most terrifying radar loops in U.S. History: the eyewall of a Category 5 Hurricane, slicing into a major city while leveling everything in its path. This is the story of Hurricane Andrew.

🚨LANDFALL: Category 5 Hurricane Melissa has struck Jamaica as the MOST INTENSE LANDFALLING ATLANTIC HURRICANE in recorded history, tying the 1935 Labor Day Hurricane with an Earth-shattering minimum pressure of 892 MBAR. Areas in Jamaica that are impacted by Melissa’s 185 MPH eyewall will likely be left unrecognizable in the aftermath of this storm’s extremely violent passage.

The previously unnamed Tropical Storm in the shallow Malacca Strait has since been given the name Senyar. The system made landfall over the city of Langsa in Aceh, Indonesia at a 50 mph (80 kph), 996 mbar peak intensity. But Senyar isn’t done. The storm has now RE-EMERGED into the Malacca Strait and is forecast to soon make a second landfall, this one in Malaysia. While Senyar won’t be very strong (potentially only ~40 mph), a Malaysian landfall by a bonafide tropical cyclone is historically rare, as few storms on record have formed this close to the equator (due to the weakness of the Coriolis Effect here).

Make no mistake, this is a monstrous Category 5 Super Typhoon that is reaching the upper echelons of plausible cyclonic intensity. Landfalling storms do not get much stronger than this. We are about to go LIVE on X and YouTube with breaking news coverage of Ragasa (NandoPH).

Super Typhoon Sinlaku’s 185 MPH peak strength a few hours ago was very close to her Maximum Potential Intensity. In other words, Sinlaku generated the highest possible sustained wind speeds that a storm could theoretically produce over these specific water temperatures and atmospheric conditions in the West Pacific. Historically speaking, this is extremely rare, and similar to what we saw with Hurricane Melissa last year in the Caribbean Sea.

The Philippines can’t catch a break in the wake of Typhoon Kalmaegi (TinoPH), because just as that system heads deeper into the Vietnamese jungle, a new leviathan has emerged from the depths of the Pacific. On the right side of this satellite loop is Tropical Storm Fung-wong, a sprawling embryonic cyclone in the Philippine Sea. She may be weak and disorganized now, but the environment ahead is going to be favorable for rapid intensification. The island of Luzon is her most likely target for landfall. Watch this one closely.

Definitely getting concerned about the storm surge threat in Baler Bay. Huge waves from Typhoon Fung-wong (UwanPH) are already crashing into the Aurora coastline of Luzon, and if the storm makes landfall just south of the bay, it could push a dangerous flow of seawater directly into Baler. Widespread reports are also indicating that substantial freshwater flash flooding is ongoing in multiple locations. Conditions across the northern Philippines will only continue to get worse from here on out.

Hurricane Melissa has shattered the global record for the DRIEST storm eye ever observed, surpassing Super Typhoon Meranti (2016). The NHC is now warning that the eyewall’s destructive winds may cause “total structural failure, particularly in higher elevations, leading to widespread infrastructural damage, prolonged power and communications outages, and isolated communities” in Jamaica. The immense detonations of lightning throughout Melissa’s 175 MPH eyewall indicate that intensification is STILL somehow ongoing. The next recon flight into this CATEGORY 5 sawblade could be historic.

UPDATE: With only a few hours left before landfall in Luzon, colossal Typhoon Fung-wong (UwanPH) has hit a new peak intensity. Her sustained winds are now at 130 MPH (210 kph), and the sea-level pressure in her giant eye has fallen to 943 mbar, making her a CATEGORY 4 storm. This will be the strongest Typhoon to hit the Philippines since Man-yi (Pepito) in November of last year, and is coming just 5 days after Kalmaegi (Tino) ravaged Cebu Island.
