Hurricane Humberto forms in the Atlantic

Humberto was upgraded to a category one hurricane at 5 a.m. Wednesday.

MIAMI (WACH/AP) -- Humberto has strengthened to a Category 1 hurricane far out in the Atlantic, becoming the first hurricane of the Atlantic season.

Humberto's maximum sustained winds early Wednesday are near 75 mph at 5 a.m. Wednesday. The U.S. National Hurricane Center says the hurricane could gain more strength before a weakening trend likely starts on Thursday.

Humberto is centered about 310 miles west-northwest of the southernmost Cape Verde Islands and is moving north-northwest near 8 mph.

It just missed the record for the latest formation of a hurricane by a few hours. That record belongs to Hurricane Gustav which formed just before 8 a.m. on September 11, 2002.

Meanwhile, Tropical Storm Gabrielle is passing west-southwest of Bermuda, hitting the wealthy British territory with wind, rain and rough surf. Gabrielle has maximum sustained winds near 60 mph.
