The storm was about 1,600 miles (2,600 km) east of the Caribbean's Windward Islands, with maximum sustained winds of 40 miles per hour (65 kph), the Miami-based weather forecaster said.
The storm is moving west at nearly 12 miles per hour (19 kph).
Danny is expected to become a hurricane by Thursday, the NHC added.
