Humberto Strengthens as Imelda Threatens US East Coast

On September 26, 2025, while Hurricane Humberto continues to strengthen in the Atlantic Ocean and is forecast to become a major hurricane, the storm that poses the greatest threat to the US is not yet a named system. Forecasters are closely monitoring a tropical wave, currently designated as 94L, which is expected to develop into Tropical Storm Imelda over the next few days.

Although Humberto is predicted to remain out at sea, it could still influence the path of Imelda through a meteorological process known as the Fujiwhara effect. The interaction between the two storms and other weather systems in the region will determine the extent of the impact on the US East Coast, the Bahamas, and potentially Bermuda. The National Hurricane Center has warned of a significant risk of wind, rainfall, and storm surge impacts for a portion of the southeast US coast early next week.
