Sure, why not! A trio of waterspouts from some towering cumulus barely producing precipitation off of Santa Monica. 👀

Sounds more like the Florida Keys...but I guess that's what local ocean temperatures 5-6F warmer that average can achieve... #CAwx

This isn’t your typical view of the Hudson River across from Manhattan — widespread ice coverage across the river this morning.

The govt lying about the killing of a U.S. citizen at the hands of the state, is by itself, a front page a story, worthy of drumbeat coverage, resignations, and impeachments.

After the US admin cancelled the $B Climate + Weather Disaster dataset, @climatecentral.org hired the scientists who ran it and set it back up.

Now the 2025 numbers are in: it's 3rd highest year on record and highest year w/o land-falling hurricanes.

Oh my…

There aren't a lot of resources for what people can do to prevent the destruction of NCAR, so I made this:

Here is the latest update from WPC on the California atmospheric river event where a moderate to high risk of flash flooding is anticipated for southern California on Wednesday Christmas Eve. Please stay safe through the upcoming Christmas holiday.
www.wpc.ncep.noaa.gov/key_messages...

Screenshot of afternoon forecast discussion from National Weather Service in the SF Bay Area. The text begins: "The biggest threat late Wednesday through Friday will be the potential for severe weather, including the risk of weak tornadoes and waterspouts. The SPC has issued a marginal risk of severe thunderstorms and a 2% chance of tornadoes/waterspouts along our entire coastline. The highest risk for a weak tornado/waterspouts will be from embedded thunderstorms within the main rain band as the cold front passes through our CWA. That being said, guidance shows the potential for isolated cells to develop in the wake of cold frontal passage which also display potential for severe thunderstorm development and rotation. This system looks even more favorable than the first system with much more instability (higher MUCAPE values over a much larger area) and continued strong low level shear between 30 to 45 knots. A marginal risk of severe thunderstorms continues for the Big Sur coastline..

One thing that really stands out about this week's California storms is the highly unusual risk of severe thunderstorms, both overnight Tue Wed and then again late Wed into Thu. Multiple low-topped supercells may generate very strong wind gusts and even a few tornadoes. #CAwx

Save NCAR from being dismantled today! The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

AGU has a Congressional email and call script up on NCAR:

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

Great talk!

Melissa Records:
Strongest Atlantic Landfall (Tie)
3rd Strongest Atlantic Hurricane (Tie)
World Record Driest/ Clearest Eye
3rd 2025 Cat 5 (2nd most)
4th Extreme Rapid Intensification Episide of 2025 (tied for 1st place)
1/

#Melissa has made landfall in #Jamaica, and has preliminarily tied the record for the lowest pressure of any landfalling hurricane in Atlantic history: 892 mb. That was last observed 90 years ago with the 1935 Labor Day hurricane.
The storm does not look like it even notices Jamaica being there.

"The NOAA aircraft left the storm early after
experiencing severe turbulence in the southwestern eyewall."

These men and women are not being paid due to the US government shutdown. Not to mention that according to AOML's director emeritus Robert Atlas, they are down 40-50% staff. #Melissa

Melissa becomes third Category 5 hurricane of the extraordinary 2025 season Updates and summaries on tropical Atlantic activity... including easterly waves, tropical storms, subtropical storms, and hurricanes.

For only the second time in recorded history, an Atlantic season has produced three Category 5 hurricanes... the previous year was 2005. This puts 2025 in an elite class of hurricane seasons. It also means that nearly 7% of all known Category 5 hurricanes have occurred just in this year.
#Melissa

Thank you National Hurricane Center, NWS and flight crews working to warn us about #HurricaneMelissa even as the government remains shutdown

Official graphic depicting potential rainfall from Melissa in the Carribbean from the National Hurricane Center. Over 30-40 inches may locally fall in the mountains of Jamaica. Note that additional rainfall may fall, beyond indicated here, outside of the 4 day window mentioned.

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.

This is my nightmare hurricane. For years I said the two scariest kinds of hurricanes were Harvey (slow soaker that won’t move) and Michael (TS to Cat 5 in like 36 hours). This is BOTH and it’s about to hit Jamaica

[Melissa forecast analysis, Friday 10/24]

The forecast is looking increasingly dire for Jamaica. Model guidance has increasingly clustered on a direct hit - Jamaica has only had close calls from five category 4 hurricanes on record - with catastrophic flooding a major concern.

This means individuals in the following statuses at the time of application are eligible: Undergraduate in the final (senior) year of a bachelor’s degree program Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed) Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar) Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded. Not be a current NSF employee. Applications that do not meet eligibility requirements will be returned without review as being ineligible for a fellowship.

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.

NOAA cancels procurement of new phased array weather radar test article Further stalls important weather research program

Important weather science news tonight: NOAA has canceled procurement of the next phased array weather radar R&D instrument. Along with the obvious blow to PAR weather research, it is consistent with other moves by admin to push forward quickly with NOAA cuts. More: https://tinyurl.com/my8hx8j6
