AccuWeather® Global Weather Center – Sept. 29, 2025 – AccuWeather® hurricane experts say the influence from a larger and stronger Hurricane Humberto will pull Imelda out to sea starting late Monday into Tuesday, reducing tropical rain and wind impacts along coastal areas of the southeast United States.  

“The rare Fujiwhara Effect between Humberto and Imedla is expected to help spare the southeast U.S. from widespread flooding rainfall. The influence from the much stronger and larger Humberto will tug at Imelda and help pull the storm away from the U.S. and out to sea,” AccuWeather® Lead Hurricane Expert Alex DaSilva explained. “Humberto and Imelda will be less than 700 miles apart at their closest pass this week. It’s quite rare to see the Fujiwhara Effect in the Atlantic basin. The interaction between the two storms should prevent Imelda from making landfall or stalling near the coast, which could have led to days of torrential rainfall and widespread flooding. The impacts could have been catastrophic.” 
 

Imelda brought heavy rainfall and gusty winds to the Bahamas over the weekend as it developed into a tropical storm.  

Imelda is expected to track roughly parallel to the east coast of Florida Monday before curving northeastward and being pulled out to sea later Monday night into Tuesday morning. Imelda is expected to gain wind intensity and become a hurricane by Tuesday. 

A wide swath of 1-2 inches of rain is expected from far eastern Florida through coastal North Carolina. There can be 2-4 inches of rain from far eastern South Carolina through southeastern portions of North Carolina, with an AccuWeather Local StormMax™ of 8 inches.  

“Heavy tropical downpours could trigger some localized flash flooding,” DaSilva said. “Imelda will bring some beneficial rainfall to areas of the Southeast that are abnormally dry or dealing with drought conditions.”  
 

The wind field will grow over the next few days, which can bring a narrow swath of 40- to 60-mph wind gusts just along the east coast of central Florida and the coastline from far northeastern Georgia through North Carolina, with an AccuWeather Local StormMax™ of 80 mph. These winds can be strong enough to down trees and cause power outages. 

Storm surge of 1-3 feet can occur from the coast of northeastern Florida to southeastern Virginia through Tuesday. A few coastal waterspouts or tornadoes are possible. 

Rain, wind and storm surge impacts along the Southeast should ease by Wednesday morning. Coastal flooding could continue along parts of the East Coast through Wednesday. 

AccuWeather® hurricane experts say Imelda and Humberto are producing rough surf and rip currents that may impact beaches from South Florida to southern New Jersey through the week and into the weekend.  
 

As Imelda soaks parts of the Southeast, Hurricane Humberto is expected to pass between Bermuda and the U.S. East Coast early this week.  

Bermuda will likely be impacted by two rounds of rain and wind when Humberto passes west of the islands late Monday through Wednesday.  

 
The second round of rain and wind from Imelda is expected to impact Bermuda between Wednesday night and Thursday night.

Due to the impacts from rain, wind and storm surge, Tropical Storm Imelda is a 1 on the AccuWeather RealImpact™ Scale for Hurricanes for the United States, Bermuda and the Bahamas. 

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.   

AccuWeather® hurricane experts are now monitoring two areas at low risk of tropical development potential in the Atlantic basin.  

One area is in the Bay of Campeche this week. People in eastern Mexico should monitor AccuWeather forecast updates for potential impacts later this week.  


The other area is west of the Cabo Verde Islands in the Atlantic main development region. People in the eastern Caribbean should monitor AccuWeather® forecast updates for potential impacts during the second week of October.
