The depression was located 1,350 miles northwest of the Cape Verde Islands on Monday afternoon and had maximum sustained winds of 35 mph, the National Hurricane Center in Miami said. It was creeping northwest at 3 mph and was expected to continue in a northwesterly direction.
The depression could strengthen into a tropical storm by Tuesday. A weather disturbance is considered a tropical storm when its winds have strengthened to between 39 mph to 73 mph. Storms become hurricanes when their winds reach a minimum of 74 mph.
Also in the Atlantic, Tropical Storm Leslie was moving north-northwest over open ocean on a track that could take it closer to Bermuda by Saturday. The storm, carrying winds of close to 60 mph, was causing potentially dangerous surf in parts of the Leeward Islands, Puerto Rico and the Virgin Islands.
In the eastern Pacific on Monday, Tropical Storm John formed near the Mexican island of Socorro but far from the mainland, the Hurricane Center said. John, with winds of 40 mph, was expected to stay at sea and weaken overnight.
