Aircraft reconnaissance data from the @53rdWRS hurricane hunters shows that Tropical Storm Jerry has max winds of around 65 mph, with the strongest winds confined north and east of the storm center. Jerry remains significantly sheared/tilted and is likely to struggle to intensify…

Tropical Storm #Jerry appears to already be vertically misaligned due to westerly shear, with the low level circulation partially exposed west of the main convective mass. This structure may delay intensification into a hurricane until/if the vortex becomes less tilted.


🌀 Tropical Storm #Jerry has formed east of the Caribbean Sea, and will pass close to the Leeward Islands on Thursday night and Friday morning. 🌀 Jerry does not yet have a well-organized inner core, but is now producing max winds of 45 mph and is forecast to intensify over the…

Hurricane #Imelda has strengthened, with aerial reconnaissance data from @53rdWRS indicating max winds are around 100 mph. Imelda is accelerating east-northeastward toward #Bermuda, where a hurricane warning is in place. Imelda is expected to pass near or over the island tonight.…

Tropical Storm #Imelda is intensifying steadily this morning as an inner convective core consolidates and becomes more compact, despite some southerly shear which continues to tilt the vortex slightly. Aircraft data from the @53rdWRS indicates max winds have increased to about 60…

#TD9 has strengthened into a tropical storm and is now officially named #Imelda. Aircraft reconnaissance data from @NOAA_HurrHunter shows a better defined core wind field, but the inner max wind ring remains asymmetric and rather wide at 50-80 NM radius, indicating that Imelda's…

Tropical Depression Nine (#TD9) continues to gradually organize north of Cuba, and may strengthen into Tropical Storm #Imelda later today. The slow motion northward into the #Bahamas has resulted in a further shift southeastward in the track forecast, with the eastward turn…

Still no development of a compact inner core wind ring with #TD9 in aerial reconnaissance data from @NOAA_HurrHunter, so the trend of gradual—not rapid—organization continues tonight.

🌀 Saturday video update on newly-formed Tropical Depression Nine (#TD9; likely to be named #Imelda later) and Major Hurricane #Humberto 🌀 TD9 is expected to bring hazardous weather to the #Bahamas and possibly eastern #Florida, #Georgia, #SouthCarolina, and #NorthCarolina.…


Some good news so far today: The GFS and ECMWF have trended farther south (closer to Cuba) with #TD9's position over the last 24-36 hours (see animations below), resulting in slower tracks northward, leading both models to flip to the "no US landfall" scenario, and rather turn…

The @NHC_Atlantic has initiated advisories on Invest #94L as "Potential Tropical Cyclone Nine (#PTC9)". This means 94L is not yet a tropical cyclone, but is expected to become one soon and threaten land areas. If/when 94L becomes a tropical storm, it would be named #Imelda.…

🌀 Friday (long!) video update on Hurricane #Humberto and Invest #94L (likely to develop and be named #Imelda) 🌀 While uncertainty in this complex forecast remains elevated, risk of life-threatening impacts to the southeastern US continues to increase. Follow your local @NWS


🌀 Thursday video update on Tropical Storm #Humberto and Invest #94L (would be named #Imelda if it develops). 🌀 These two storms are raising risks to the #TurksAndCaicos, #Bahamas, southeastern US, and #Bermuda this weekend and next week, though uncertainty remains high. Have a…


🌀 Wednesday video update on two tropical systems expected to develop and bring impacts to the southwestern Atlantic region this week and next week:


🌀 A pair of tropical waves (#93L and #94L) in the central Atlantic have a chance to develop into tropical cyclones this week as they travel north of the Caribbean. 🌀 Environmental conditions may be suboptimal for the eastern wave (93L) late week as it interacts with an…
