The Cayman Islands are under a tropical storm warning and a hurricane watch, as a new tropical depression is taking shape in the northwest Caribbean Sea.

The U.S. National Hurricane Center says the system could strengthen into Tropical Storm Wilma later Sunday. Wilma would be the 21st named storm of the Atlantic hurricane season, tying a record set in 1933.

Long-range forecasts show the storm possibly moving into the Gulf of Mexico next week. Several U.S. cities along the Gulf coast are still reeling from Hurricane Katrina.
