Tropical Storm Nana is expected to become a Hurricane as it approaches Central America, while Tropical Storm Omar formed east of South Carolina the National Hurricane Center in Miami said Tuesday.
An Air Force Reserve Hurricane Hunter aircraft crew flew into Nana as it took shape south of Jamaica, recording maximum sustained winds of 50 mph (85 kmh) with higher gusts.
The hurricane center says Nana was centered about 425 miles east of Limon, Honduras, and was moving west at 18 mph on a path that could damage Belize, Honduras, Guatemala and southernmost Mexico. Strong winds, dangerous storm surges and flash flooding are becoming more likely.
Omar is not expected to deal as much damage. The storm is forecasted to have a brief lifespan as it moves further east into the Atlantic Ocean at 15 mph with maximum sustained winds of 40 mph.
Nana and Omar are the earliest 14th and 15th named storms on record, beating the 2005 arrivals of Nate on Sept. 6 and Ophelia on Sept. 7, according to Colorado State University professor Phil Klotzbach.
Omar is expected to degenerate into an area of low pressure by Thursday.
