Tropical Storm Gaston getting stronger in the Atlantic

Tropical Storm Gaston is strengthening as it moves over the far eastern Atlantic.

The storm's maximum sustained winds had increased Tuesday to 65 mph (100 kph). The U.S. National Hurricane Center says Gaston is expected to become a hurricane by Wednesday.

Gaston is centered about 765 miles (1,230 kilometers) west of the southernmost Cabo Verde Islands and is moving west-northwest at 18 mph (30 kph).

The storm is expected to turn toward the northwest and decrease in forward speed in the next couple of days.

Elsewhere, Fiona broke apart in the Atlantic and Kay became a remnant low in the Pacific.

Forecasters continue to watch a tropical wave situated over the Lesser Antilles, which could bring heavy rain to parts of Florida for the weekend.   Stay tuned to FOX 35 each day this week for updates.  You can also track the storm at
