Hurricane Gaston expected to weaken; next storm could organize Thursday

MIAMI, Aug. 25 (UPI) — The U.S. National Hurricane Center said Hurricane Gaston should weaken back into a tropical storm on Thursday while another disorganized storm system remains a threat.

Hurricane Gaston has maximum sustained winds of 75 mph and is about 1,200 miles east of the Leeward Islands.

“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 is forecast Friday night,” the National Hurricane Center said in a statement. “Hurricane-force winds extend outward up to 25 miles from the center, and tropical-storm-force winds extend outward up to 90 miles.”

If weakened back to a tropical storm, Gaston is expected to re-strengthen on Saturday and beyond but it is not forecast how much it will re-intensify.

Meanwhile, tropical weather system Invest 99L could become a tropical storm on Thursday or Friday as it heads toward the Bahamas. If the weather system becomes a storm, it will be called Tropical Storm Hermine.

Invest 99L has not formed a well-defined circulation center, making forecasting on the system unclear. The tropical wave composed of disorganized thunderstorms could reach South Florida by late Sunday. It has a potential of becoming a hurricane.

More calculated forecasts and tracking models related to Invest 99L are expected later on Thursday when the storm system is expected to organize into a tropical storm.
