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.

Tropical Storm Imelda got stronger on Monday morning and could become the season’s fourth hurricane on Tuesday, according to the hurricane center. Tropical storm warnings remained in effect for parts of the Bahamas on Monday.

As of Sept. 29, the National Weather Service in Miami was planning on replacing a tropical storm warning for Palm Beach County coastal waters with a small craft advisory through at least the night of Oct.

A strengthening storm brewing near the Bahamas could bring flooding rain, coastal surge, damaging winds and dangerous surf to the Southeast.

While Tropical Storm Imelda and Hurricane Humberto are expected to remain off the coast of Florida, indirect impacts can be expected.

Experts say that the complex interaction between the two storms have changed the initial forecasts, and that "the impacts could have been catastrophic.”

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.

A combination of weather factors and geography helped make it one of the most brutal storms in the modern history of hurricanes.
