That's an unlikely outcome, said CBS News meteorologist Nikki Nolan. But if such a collision does occur, it could produce what's called the Fujiwhara effect, a rare phenomenon in which two different storms merge and become entangled around a newly formed, common center.

The National Hurricane Center's 11 p.m. Monday update reported that Category 4 Hurricane Humberto is in the Atlantic Ocean, 295 miles southwest of Bermuda. Packing maximum sustained winds of 140 mph, the hurricane is tracking north-northwest at 13 mph.

Homeowners in the Southeast U.S., the Bahamas, and Bermuda should prepare for two major storms in the coming days

Tropical Storm Imelda’s radical right turn away from Florida and a U.S. landfall added to an already oddball hurricane season that has included an unprecedented primetime nap, three high-octane hurricanes and a brush with the rare Fujiwhara Effect.

Hurricane Humberto has strengthened into a Category 4 hurricane, forecasters warning of dangerous surf and rip currents in parts of the northeastern Caribbean and Bermuda.

Hurricane Humberto will kick up the surf and potentially trigger rip currents at Rhode Island beaches later this week.

The 2025 Atlantic hurricane season is heating up but so far storms seem to be avoiding Florida. Why? Has it happened before?

One man has died in a landslide in Cuba as Imelda continues to move through the Caribbean Monday, according to a report from the Associated Press. The death came as schools closed in the Bahamas amid heavy rains across the region, which were expected to produce both flash and urban flooding, according to the National Hurricane Center (NHC).
