The U.S. National Hurricane Center in Miami said Thursday that the depression was still nearly 1,200 miles (1930 kilometers) east of the Windward Islands. It had maximum sustained winds of 35 mph (56 kph) and was moving west at 20 mph (32 kph).
It's expected to strengthen into Tropical Storm Leslie later in the day, once its winds reach at least 39 mph (63 kph).
The depression currently poses no threat to land and is expected to gradually start moving to the northwest, well off the U.S. coast.
