The area of low pressure off the African coast has become tropical depression 4. Maximum sustained winds associated with it are 35 miles per hour and it will continue to the west-northwest at 20 miles per hour. The 5 AM forecast has the depression crossing the Atlantic and may strengthen to become a tropical storm during the overnight hours. By Monday, it should be just east of Puerto Rico. There is still some uncertainty whether it will be able to maintain tropical storm strength that far out, because it will be passing through an area of dry air in the Atlantic. That dry air would attempt to tear apart the storm.
The rest of the Atlantic Basin is not expected to experience tropical development within the next 48 hours.
