Invest 94-L, a weather system in the Atlantic, has the potential to develop into Tropical Storm Tammy, according to meteorologists. The system is currently moving westward and could impact the Windward/Leeward Islands in the next 7+ days. Forecast uncertainty remains, but Caribbean islands are advised to closely monitor the situation. The National Hurricane Center has given 94-L an 80% chance of tropical development. The next named storm will be Tammy. The system's organization and potential for tropical storm watches for the Leeward Islands are being closely watched by meteorologists.
Invest #94L is becoming better organized, with the wave cusp now rolling into what may be a closed circulation, if a bit elongated. 94L could become a tropical storm at any time, and @NHC_Atlantic may issue Tropical Storm Watches soon for the Leeward Islands, as a… https://t.co/nviX8cF5lp https://t.co/NaPostO4uZ

#94L continues to be a forecast enigma. Huge discrepancy between GFS and ECMWF suites on whether we have a TC near/east of the Lesser Antilles this weekend. The system has gotten a little better organized since yesterday, but it's not clear if that's reflected at the surface. https://t.co/RAbxiEPCxk
#94L still struggling to maintain convection at the moment. Between this and the forecast trend towards more SW shear east of the islands, I think the intensity of this may be capped. Surprised at the overall lack of organized convection right now - might be dry air getting in. https://t.co/qd8r2AXsoB
While some of the overnight convection wanted, #94L is looking fairly organized this morning. Models continue to trend towards this developing into a TC in the coming days. Could be at least a close call for the Eastern Caribbean. Still lots to sort out with the forecast. https://t.co/12JMpW0pMF
Overnight trends were not great likely due to #94L getting significantly better organized. The 00z EPS agrees on the system becoming a robust storm east of the islands, with some signal for a strong hurricane in the area. Those in the Lesser Antilles should keep an eye on this. https://t.co/BneRELliyy
Tammy! Is that you? Chances of tropical development in the far eastern Atlantic continue to increase - a bit unusual for so late in the hurricane season. The developing system will continue to slowly move westward toward the Caribbean over the next 7 days. #SCwx @WMBFnews https://t.co/maAAq7zLKI
It’s not an area of the Atlantic we’d normally look to for tropical trouble, but if 2023 has taught us anything, it’s that hurricane season isn’t exactly following its traditional calendar. My latest discussion on Invest 94L 👇 https://t.co/AaPbDXtMce https://t.co/IOxs3VCnnf
Still a ton of forecast uncertainty with #94L - the 00z guidance showed more westerly shear near the islands compared to yesterday's scary 12z runs. Still a lot of questions too about where (and even whether) it forms. Still, Caribbean islands should keep a close eye on it. https://t.co/0GSsxq09m8
Definitely some favorable factors in #94L's environment next week. Solid mid-level moisture, although there is some dry air to the NW. The big thing that makes it concerning is the possibility of being between two upper troughs, leading to two outflow channels - rarely ends well. https://t.co/eGp0Pjcloi
#94L continues to move slowly west. Not in any hurry to move across the Atlantic this late in the season. Global models still suggest development to varying extent. Remains to be seen exactly how favorable the upper pattern is, and whether it makes it into the Caribbean. https://t.co/jrwlo7o5fj
We monitoring INVEST 94-L. Forecast tracks move this westerly and many computer models bump this into the Windward/Leeward Islands area in 7+ days. Tropical development is possible. Next named storm is Tammy. https://t.co/GfR1E9NU2K
