A tropical depression has formed in the eastern Atlantic, about 1,665 miles east of the Windward Islands, and forecasters say it will become a tropical storm soon and a hurricane later this week.
Tropical Depression Four is expected to become Tropical Storm Danny later today and then develop into a hurricane by late Thursday or Friday.
The system is carrying maximum sustained winds of about 35 miles per hour, and is moving west at about 13 miles per hour, according to the advisory issued at 11 a. m. by the National Hurricane Centre in Miami.
It is expected to move slowly to the west-northwest later tonight or tomorrow and computer model forecasts indicate it may reach near the Caribbean Sea in a week.
Tropical Storm Danny would be the fourth storm of the 2015 Atlantic hurricane season but the only one to threaten the Caribbean. Previous tropical storms – Ana, Bill and Claudette – took aim at the United States coast.
The hurricane season has so far been slow and is expected to stay that way as a result of a strong El Niño and cooler temperatures in the Atlantic, among other factors.
Earlier this month, the National Oceanic and Atmospheric Administration Climate Prediction Center issued an updated outlook for this year’s hurricane season which indicated the probability of a fairly quiet season is now 90 per cent. It said there might only be one major hurricane even though the season could produce as many as 10 named storms.
