MIAMI (CBSMiami) – Tropical Storm Gaston expected to become a hurricane again over the weekend.

At 11:00 p.m. Thursday, the center of the system was about 1075 miles east-northeast of the Leeward Islands.

Gaston’s maximum sustained winds are hovering at 65 mph with higher gusts. Tropical-storm-force winds extend outward up to 115 miles from the center.

Gaston is moving toward the northwest near 17 mph, and this general motion is expected to continue through Friday.

A turn toward the west-northwest and a decrease in forward speed are expected by Saturday.

Little change in strength is expected Thursday night or Friday but restrengthening is anticipated to begin Friday night, and Gaston is forecast to become a hurricane again on Saturday.

Gaston was the third hurricane of this year’s season.

There are no coastal watches or warnings in effect.

Meanwhile, we are keeping our eyes on a tropical wave southeast of the Turks and Caicos Islands which is producing gale-force winds over water to the north of the Virgin Islands and Puerto Rico. Satellite images indicate that the shower activity remains disorganized, and the low continues to lack a well-defined center. Although upper-level winds are only marginally conducive for development, this system could still become a tropical cyclone during the next couple of days.

Because of the large uncertainties regarding this system’s development and future track, it is too early to speculate on what specific impacts it may have on South Florida and the Bahamas.
