Expected impacts from this weekend's major SoCal storm--which now appears likely to feature widespread flood risk and also a few severe thunderstorms--continue to increase. I will have a blog post and YouTube livestream at a TBD time later today to discuss. #CAwx

Jamaicans take stock after Hurricane Melissa causes damage, flooding and power cuts

With communication networks in Jamaica crippled, the true scale of the disaster remains unknown.

The satellite derived wind field really puts the scale into prospective. Around half the Jamaica will see hurricane force winds from Melissa, but several parishes (Westmoreland, Saint Elizabeth, Manchester, Saint James, Trelawny) will see extreme winds over 95kts/110 mph. Higher in the mountains.

#Melissa unfortunately is still intensifying. A 9am EDT Tropical Cyclone Update indicates that winds are up to 180 mph, with an estimated minimum pressure of 896 mb. You can see how GLM lightning has 📈 in the past hour, encircling the eye, with eye WV temp still increasing!

Waiting on a dropsonde to confirm, but Melissa is most certainly below 900 hPa right now. Tragically we are about to witness the 2nd or 1st deepest Atlantic hurricane landfall by min MSLP on record in Jamaica.

What we're witnessing with #Melissa is ultra rare in the history of known hurricanes in the Atlantic. This level of sustained intensity and feasting on every joule of ocean heat content without any real disruption is incredible. Not hyperbole: Jamaica is facing a generational catastrophic event.

Melissa has rapidly intensified into a category 4 major hurricane according to preliminary NHC estimates: - from 60 to 120 kt in 24 hours (⬆️ 60 kt) - from 90 to 110 kt in just 6 hours (⬆️ 20 kt) This slow-moving storm will not only deliver damaging winds & storm surge but also catastrophic rainfall.

Recon is finding #Melissa notably stronger, at about 85kt with pressure having dropped all the way to 971mb. The wind field is much more coherent and symmetric, and there are double hot towers trying to surround the eye. Could see some impressive intensification rates from recon this evening

Jamaica, in particular, will likely suffer catastrophic impacts from now rapidly-intensifying (but slow-moving) Hurricane #Melissa. A *Category 5* landfall now appears to be the most likely outcome, & 30-40+ inches of *additional* rain in mountains will lead to extreme flooding.

With the GFS coming more in-line with the rest of the model guidence this afternoon, it confirms that Tropical Storm Melissa will produce near-historic amounts of rainfall and flooding for Jamaica, Hispanola, and eastern Cuba when it makes landfall as a major hurricane.

Half-baked notion, so caveats. But if LLMs are basically trained on our collective work without permission or consent and then used to routinize much of that work, a large share of the capital gains should go to a national fund dividend, analogous to the Alaska Fund, that pays us all.

The elevated precipitable water over Florida this week will certainly increase the flash flood threat. Though tropical development may still be lacking until after the disturbance crosses over the state, it's going to be the area to watch over the next few days.
