There is an increasing risk of dangerous wind and storm surge impacts along portions of the northern Gulf Coast. Watches could be required on Wednesday. Residents from Louisiana to the Florida Panhandle should closely monitor the latest forecast updates and ensure they have a hurricane plan in place
National Hurricane Center forecast cone for Tropical Depression Nine, issued Tuesday, October 6, 2026. The depression is located over the southwestern Gulf of Mexico with maximum sustained winds of 35 mph. The forecast track takes the system northeast across the Gulf, with strengthening to a hurricane possible before reaching the northern Gulf Coast near the Florida Panhandle Friday. The system is then forecast to move inland through the Southeast and toward the Ohio Valley over the weekend. The cone represents the probable path of the storm’s center and does not show the storm’s size.Preliminary probability forecast for tropical-storm-force winds from Tropical Depression Nine through Sunday, October 11. The highest probabilities extend from the central Gulf of Mexico northeast toward the northern Gulf Coast, with the greatest chances offshore south of Alabama and the Florida Panhandle. Lower probabilities extend into coastal Louisiana, Mississippi, Alabama and the Florida Panhandle.

NEW: In March the White House released an FY27 budget request that zeroed out the National Science Foundation's directorate of Social, Behavioral and Economic Sciences (SBE). For months it was unclear what would happen. Now, with FY26 over, the damage to SBE is coming to light. My reporting:

Scoop: For nearly a year, NSF has struggled to make new grants. Now we know that it will not catch up. In fact, NSF will award just 6,100 new grants—a 30% y/o/y decline, itself down from a previous avg. of 11,000+. In fact, the last time NSF awarded so few grants was in the early '80s.

NIH grants have been under political scrutiny since early 2025. But what does the screening process actually look like? What is being flagged? I spent a month digging into leaked docs and emails. We've published the 235-word list that are being flagged by an internal AI tool. And so much more. 🧵

Hi everyone! With the abstract submission deadlines for the 2026 AMS Madison Joint Summit coming up, wanted to advertise these student award and travel opportunities available via the AMS WAF/NWP conferences. Feel free to spread the word to any interested students!
Weather Analysis and Forecasting / Numerical Weather Prediction Conference Student Travel Grant Awards

Student presentations selected as part of the 34WAF/30NWP conferences have the option of being judged, with a $50 award going to the top 3 oral and poster presentations in each conference (12 awards total). 

Also, once abstracts have been submitted, the WAF/NWP committee will offer three $375 travel grants to students whose abstracts have been accepted. 

Students who wish to be considered for a travel grant must send the following documents to the program chairs (austin.coleman@noaa.gov, john.lind@noaa.gov, jbravo2@stevens.edu, and tomer@windbornesystems.com) no later than Friday, April 3rd, 2026:
Statement of why they wish to attend the WAF/NWP conferences
- Statement of commitment to attend if they receive the travel grant
- Letter of support from their advisor
- Ensure that you have submitted an abstract to the WAF or NWP conferences before the abstract submission deadline
