The U.S. National Weather Service has upgraded a tropical depression in the Caribbean Sea to a tropical storm - named Wilma.
The 21st named storm of the Atlantic hurricane season ties the record set back in 1933. The hurricane season does not officially end until November 30.
Tropical Storm Wilma is 280 kilometers southeast of Grand Cayman Island with winds of 65 kilometers an hour, and is slowly moving southwest.
A tropical storm warning and hurricane watch have been issued for the Cayman Islands. Forecasters say Wilma will probably dump heavy rains there and on Jamaica.
Long-range forecasts show the storm possibly moving into the Gulf of Mexico later this week, potentially developing into a significant hurricane.
