Cuba is weathering strong winds and heavy rains from Tropical Storm Fay, which is expected to cross the island early Monday before heading toward Florida.

Forecasters at the National Hurricane Center in Miami say the storm could approach hurricane strength as it moves westward over Cuba and enters the Florida Straits. A hurricane watch is in effect for parts of Florida, including the Keys.

State officials have asked visitors to evacuate the Florida Keys. Several schools have also been closed because of the storm. At last report, Fay was centered 430 kilometers southeast of Key West and was packing 85-kilometer per hour winds.

The tropical storm caused at least 10 deaths as it moved across Haiti and the Dominican Republic.

Officials in Haiti said seven people had been killed and two were missing as a result of the storm. Floodwaters killed a woman and two children in the Dominican Republic.

A tropical storm watch is also in effect for Grand Cayman island. People in Florida and the northwestern Bahamas were advised to monitor the storm's progress.

Fay is the sixth tropical storm of the 2008 Atlantic hurricane season.
