The hurricane's maximum sustained winds Friday had increased to near 115 mph (185 kph). The U.S. National Hurricane Center says the hurricane is not expected to intensify, and a weakening trend is forecast to begin later Friday.
The hurricane is centered about 900 miles (1448 kilometers) east of the Leeward Islands.
Hurricane Danny doesn't currently pose a threat to land but the hurricane center says those in the Leeward Islands should monitor its progress.
