Congratulations to our @amstropical.bsky.social award winners! @adamsobel.bsky.social received the Joanne Simpson Tropical Meteorology Research Award. @tcblers.bsky.social, Andrew Hazelton, Frank D. Marks, Ghassan J Alaka Jr, and Chunxi Zhang received the Banner I. Miller Award. #AMS2026

Category 5 Hurricane Melissa made landfall today near Black River, Jamaica with 185 mph winds and is currently re-emerging near Falmouth. If you have the means, I strongly encourage you to consider donating to a relief effort.

The western end of Jamaica where #Melissa is projected to make landfall has the least well-built structures of anyplace on the island. Graphic is from a 2021 paper, "Poverty and hurricane risk exposure in Jamaica": www.researchgate.net/publication/...

Thanks to some vigilant friends out there, I have a nearly-complete 87-hour radar loop of #Melissa 's approach to #Jamaica. The loop abruptly ends when the radar is lost (either loss of communication with it or loss of the actual structure).

NEW: Devastating imagery from Jamaica, before & after Category 5 Hurricane Melissa.

Black River — near total destruction.

Thanks for digging into this, Brian! I previously only focused on the peak intensification rate but even the difference in the period from cat-1 to cat-5 is less than 3 hr. This is a surprise but great to know!

Thanks to the hard work of the UAH staff, the press release was successfully synchronized and published live.

We’ve been waiting for this LES landfall paper for a while. Glad to work with @agitatedcu.bsky.social on this exciting publication, as it sets up the stage for our upcoming NSF WHIRLTC project.

Exciting to have @mikefischerwx.bsky.social to share his hurricane research at the UAH AES seminar and BLM class. Students showed high interests in the TC-RADAR dataset and future AI applications of aircraft observations. An extended Q&A session is the testament. Way to go, Professor :)

The Florida state snowfall record appears to have fallen.

Glad to see your TC talk again! Not sure if I see this correctly. Is the track reflection related to the transport of PV, generated by island convection, to the northern TC circulation?

Is this the one you were waiting for? Congratulations! What a holiday gift!

Are rapidly intensifying tropical cyclones associated with unique vortex and convective characteristics? Abstract The largest tropical cyclone (TC) intensity forecast errors are typically associated with episodes of rapid intensification (RI). Here, we explore whether TCs that undergo RI are associated w...

"Are rapidly intensifying tropical cyclones associated with unique vortex and convective characteristics?" Well, you can find out more here: doi.org/10.1175/MWR-...

I'll summarize in the thread below.

Thank you Professor :)

🌀Our TCBL lab🌀is admitting a M.S. (or Ph.D.) student to study boundary layer winds and tornadoes of landfalling hurricanes from Fall 2025. Students with a strong passion for hurricane science and a strong background of programming/physics are particularly encouraged to apply. Welcome to spread out!

This is why we love the tropical. #Miami
