Tropical Storm Dexter, the fourth named system of the 2025 Atlantic hurricane season, formed late Sunday night well east of North Carolina. The system is now moving away from the U.S. East Coast, posing no land threat, but it signals a shift toward more frequent tropical development in the Atlantic.

As we enter August, the Atlantic Hurricane Season really begins to ramp up. The National Hurricane Center says on average, 86% of named storms happen after August 2.

Hurricane forecasters were tracking three disturbances in the Atlantic Ocean Sunday afternoon, one of which is expected to briefly become the season's fourth named storm as it moves away from the U.S. UPDATE: Tropical Storm Dexter forms in Atlantic as forecasters track two other disturbances
