Hurricane Humberto showed rapid intensification and became a Category 5 storm at the 5 p.m. Saturday advisory from the National Hurricane Center. Humberto is now a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Two people have died and at least five homes have collapsed as a result of the twin storms that are fewer than 500 miles apart in the Atlantic Ocean.

ORLANDO, Fla. – Hurricane Imelda on Wednesday morning continued to strengthen and become better organized, with satellite imagery showing a more defined eye and a symmetric structure. Winds have increased to around 90 mph, and further strengthening is expected as it accelerates east-northeast toward Bermuda.

Predictions on how Humberto could affect Florida and the U.S. are difficult due to the Fujiwhara effect. Humberto strengthened rapidly on Sept. 26 and is now a major Category 3 hurricane, according to the latest advisory from the National Hurricane Center.

If Humberto becomes a major hurricane as expected, it will be the first time since 1935 when a season's first three storms were Category 3 or higher.

Meanwhile, Tropical Storm Humberto is chugging along in the open Atlantic, where it’s expected to become a hurricane over the weekend and potentially a major hurricane early next week.

Hurricane Humberto is now a Category 5 storm, and Tropical Depression Nine is expected to strengthen into a hurricane by Tuesday, according to forecasts.
