Tropical Storm Gabrielle (2025)

Storm Active: September 17-

A tropical wave entered the Atlantic ocean around September 12 and moved slowly westward over the next several days. It produced a significant amount of thunderstorm activity but remained quite disorganized. The system was eventually designated Tropical Depression Seven on September 17. At the time, it was a little past halfway from Africa to the Windward Islands. Despite achieving tropical depression status, the cyclone was still a mess, with almost all convection displaced east of the center. Furthermore, the center itself was a warring group of vorticies rotating around one another. Later that day, the center reformed further north, coaxed poleward by an upper-level low over the subtropics. The storm's winds also increased enough that it was upgraded to Tropical Storm Gabrielle.

Gabrielle evened out to a more steady west-northwest heading on the 18th and consolidated its circulation, but struggled to produce thunderstorm activity. For most of the day, it was little more than a naked swirl. That evening, it began to put up a better fight against westerly wind shear and storm activity blossomed in the eastern semicircle. Nevertheless, atmospheric conditions remained hostile through the next day.

As of 5:00pm EDT on September 18, 2025, Tropical Storm Gabrielle had maximum sustained winds of 50 mph, a minimum central pressure of 1004 mb, and was moving west-northwest at 13 mph.
