Tropical Storm Humberto forms in Atlantic. Maps show its forecast path.

Tropical Storm Humberto formed Wednesday in the central tropical Atlantic, and it is anticipated to move northwestward through the next several days, according to the National Hurricane Center.

The storm is one of two systems swirling over the western Atlantic that could potentially bring some downstream impacts to parts of the Southeast U.S. coast from Florida up to North Carolina, director of the Miami-based hurricane center, Dr. Michael Brennan, said.

Currently, there are no coastal watches or warnings in effect. 

Tropical Storm Humberto forecast and path

As of the NHC’s Wednesday evening update, Humberto is located about 505 miles northeast of the Leeward Islands. It is moving west-northwest at about 12 mph with maximum sustained winds of 45 mph.

“Steady strengthening is forecast during the next several days,” the hurricane center said.

Tropical-storm-force winds extend outward up to 45 miles from the center of Humberto.

Due to warm sea surface temperatures and mid-level relative humidity, Humberto is “within a favorable environment for strengthening,” the NHC said.

It is the eighth named storm of the 2025 Atlantic hurricane season. The tropical storm comes on the heels of Hurricane Gabrielle, which is not impacting land and is forecast to head farther out into the Atlantic.

Another storm system brews over the Caribbean

The hurricane center said it is also closely monitoring a second storm system over the northeast Caribbean in the Atlantic near Humberto.

The system is likely to become a tropical depression late this week, forecasters said.

It is likely to bring heavy rains near Puerto Rico and the Dominican Republic through Wednesday before strengthening near the Bahamas, according to the NHC.
