CHARLESTON, SC (WCSC) - Danny has become the first hurricane of the Atlantic Season.
The National Hurricane Center upgraded Tropical Storm Danny to a Category 1 hurricane Thursday morning.
The storm is moving west-northwest at about 12 mph, and this general motion is expected to continue over the next few days, forecasters say.
At 10 a.m., the eye of the storm was located near latitude 12.5 north, longitude 44.8 west. That placed it about 1,090 miles east of the Winward Islands.
Meteorologist Justin Lock says very dry air in the middle levels of the atmosphere is likely to keep the storm from strengthening a great deal. The current forecast track takes it toward the eastern and northeastern Caribbean by Tuesday.
Maximum sustained winds are at 75 mph with higher gusts. Forecasters expect some strengthening over the next 48 hours, but say the storm is expected to weaken as it approaches the Leeward Islands.
Hurricane-force winds extend only up to 10 miles from the center, while tropical-storm-force winds extend up to 60 miles outward.
