Tampa Bay could face its rainiest day of the week Thursday as a slow-moving front and unusually high atmospheric moisture bring waves of showers and thunderstorms into the region.
Man it is really going to torrentially pour in central Florida at times Thursday late morning through the afternoon. A front draped across the I-4 corridor. I would fully expect somewhere to get nailed with rain. Some models show somewhere getting 5"+ rain tomorrow.

Why it matters: Storms may produce torrential rainfall rates capable of overwhelming roads and drainage systems in a short period. Some forecast models indicate isolated locations could receive more than 5 inches of rain.
The latest:
- Rain could begin moving inland from the Gulf around 4 to 6 a.m.
- Coverage is expected to increase between 7 and 10 a.m.
- Periods of heavy rain and thunderstorms may continue from late morning through the afternoon.
- The front is expected to settle near the Interstate 4 corridor, placing much of Tampa Bay and central Florida in an unsettled weather pattern.
- Rain chances could reach 60% to 80% across parts of the region.
Main threats:
- Torrential downpours.
- Localized street and poor-drainage flooding.
- Frequent and vivid lightning.
- Strong wind gusts.
- Slow-moving storms that repeatedly pass over the same communities.
- Isolated severe weather, including winds near 60 mph or hail around 1 inch in diameter.
Tampa Bay timing:
Morning commuters could encounter heavy rain, standing water and reduced visibility. Storms are expected to gradually spread from north to south, placing areas near Tampa, St. Petersburg, Clearwater, Bradenton and Sarasota at risk through the afternoon.
Flood safety:
- Never drive through a flooded roadway.
- Slow down and increase following distance during heavy rain.
- Avoid low-lying streets and known flood-prone intersections.
- Move indoors when thunder is heard.
- Keep phones charged and weather alerts enabled.
- Secure loose outdoor items before stronger storms arrive.
What follows:
The front is expected to slow as it moves south Friday, keeping clouds and scattered storms in the forecast. Rain may become less widespread, but additional downpours remain possible, especially during the afternoon.
Bottom line: Thursday is not expected to bring steady rain every minute, but several hours of intense downpours could create dangerous travel and flooding conditions across Tampa Bay. Be ready for rapidly changing weather from the morning commute through the afternoon.
