Atlantic: Tropical Storm Andrea (01L)

Invest 90L has managed to beat the odds and become a tropical storm - Tropical Storm Andrea, the first named storm of the 2025 Atlantic hurricane season. However, Andrea will soon be gone as environmental conditions - which are already hostile - will become even more hostile as the storm accelerates northeastward over the open Atlantic. The little bit of convection it has will evaporate quickly as shear increases and sea surface temperatures drop below 24°C, and Andrea should become a post-tropical remnant low pressure area by this evening.

So why name it at all? Observations suggest that Andrea has probably been a tropical cyclone for at least a day, and so it appears likely that when the National Hurricane Center does its post-season analysis on the storm, they will find that it actually formed earlier and adjust its best track accordingly. This happens from time to time, and sometimes storms like this even go unnamed, such as an extremely unusual subtropical storm that formed off the U.S. East Coast in January 2023, becoming the first subtropical or tropical cyclone to form in the month of January since Hurricane Alex in 2016.
