Humberto expected to pull developing tropical storm away from the U.S. East Coast

Rainfall totaling 4-8 inches is forecast across coastal areas of the Carolinas through Wednesday.
> Humberto and the emerging storm will likely produce rough surf and dangerous rip currents at beaches from South Florida to the mid-Atlantic through the week and into next weekend.
AccuWeather® Global Weather Center – Sept. 26, 2025 – AccuWeather® hurricane experts say Hurricane Humberto is expected to tug a developing storm out to sea and away from the Southeast early this week, reducing the tropical rain and wind impacts in the United States. The next name on the list of Atlantic storms is Imelda.
“The size and strength of Hurricane Humberto will exert more influence on this developing storm and cause it to be pulled out to sea and away from the East Coast. This expected interaction between the two storms should spare the Southeast from a landfall,” AccuWeather® Senior Meteorologist Renee Duff said. “The storm’s proximity to the east coast of Florida, Georgia and the Carolinas will cause heavy rainfall in some areas with a potential for flash flooding. Rain totaling 4-8 inches can fall from just north of Charleston, South Carolina, to Wilmington, North Carolina. Rough surf, rip currents, beach erosion and coastal flooding created by both storms will remain a concern throughout the week from South Florida through the mid-Atlantic, even as both storms move out to sea.
The developing storm near the Bahamas is forecast to intensify into a tropical storm as it moves north, bringing heavy rain, gusty winds and some storm surge to the islands. It may intensify into a hurricane off the Southeast U.S. coast early this week.
AccuWeather® hurricane experts say a swath of 1-2 inches of rain is expected from far eastern Florida to North Carolina. There can be 4-8 inches of rain from far eastern South Carolina through southeastern portions of North Carolina, with an AccuWeather Local StormMax™ of 18 inches, most likely across the northern Bahamas.
“Periods of heavy rainfall can trigger dangerous flash flooding. Do not try to drive down flooded roads,” Duff said. “Much of this rainfall will be beneficial in areas that are dealing with abnormally dry or drought conditions, which have expanded across Georgia and the Carolinas.”
The wind field from this storm is expected to grow in size as it moves northward to the Southeast U.S. This can bring a wide swath of 40- to 60-mph wind gusts along the east coast of central Florida and from far eastern Georgia to North Carolina, with an AccuWeather Local StormMax™ of 80 mph. Gusty winds can be strong enough to down trees and cause localized power outages.
Storm surge of 1-3 feet can occur along parts of the Southeast U.S. into Tuesday night. Some coastal inundation and minor beach erosion are also possible.
Due to flooding rain, damaging winds and dangerous seas, Tropical Depression 9 is a 1 on the AccuWeather RealImpact™ Scale for Hurricanes in the Bahamas, the Caribbean and the United States.
A 1 on the AccuWeather RealImpact™ Scale for Hurricanes warns of localized flooding, damage to unanchored mobile homes, vegetation and signs. Localized power outages and coastal inundation resulting in some property damage is also possible.
Humberto strengthened into a monster Category 5 hurricane over the weekend in the Atlantic, becoming the second storm to reach Category 5 strength this season. Humberto is forecast to pass between Bermuda and the U.S. East Coast early this week, bringing gusty winds and rain to the islands between Tuesday and Wednesday.
Bermuda may again receive tropical impacts from Wednesday night through Thursday night, this time from future Imelda as the storm makes its closest approach and brings another round of rain and wind.
