TAMPA, Fla. — Tropical Storm Helene has formed in the northwestern Caribbean Sea. It's expected to move into the Gulf of Mexico over the next 48 hours.
The National Hurricane Center says hurricane and storm surge watches have been issued for parts of Florida's Gulf Coast, including the Tampa Bay area, ahead of potential impacts from the storm. It is expected to become the season's next hurricane by Wednesday.
Before forming, the NHC had been monitoring the system as Potential Tropical Cyclone 9, which allowed forecasters to begin tracking the storm before it became fully organized.
As of the latest advisory, Tropical Storm Helene is about 175 miles south of the western tip of Cuba. It's moving at 12 mph with maximum sustained winds at 45 mph.
Timing: Late Wednesday - early Friday
Late Wednesday is when the first rain bands arrive and severe weather is possible.
Thursday, the system will be parallel to Tampa Bay, passing our area and bringing us a surge. Thursday will be the day with the most severe impacts from the storm, with bands of rain and wind. The surge begins later in the day.
Early Friday, our winds shift out of the southwest as the system leaves our area. Flooding and surge will be the major concern. Conditions return to normal on Saturday with typically showers and heat.
Impacts:
Surge: Pinellas, Hillsborough, and Pasco counties could see 5-8 feet, while northern counties could see 6-10 feet of storm surge
Rain: 4-8 inches possible
Wind: 45-55+ mph sustained winds
Severe Weather: Isolated tornadoes possible, a level 1 risk
