A surge of tropical moisture could bring several days of heavy downpours, localized flooding and isolated severe storms to the Tampa Bay area, even if no named storm develops.

**Why it matters:** A slow-moving Gulf disturbance is expected to bring several days of heavy rain, localized flooding and gusty storms to the Tampa Bay area, even though tropical development remains unlikely.

**The latest:**

- National Hurricane Center forecasters give the system a **20% chance** of tropical development over the next seven days.
- Forecast models show the disturbance drifting slowly east across the northeastern Gulf and Florida through early next week.
- A flood advisory was issued for parts of Pinellas County Friday morning as storms moved through the region.

> TROPICS UPDATE: GRAF model shows the possible timing and movement of the Gulf low over the weekend. It could be a significant rain-maker for the Florida Gulf coast, as the models show very slow drifting towards the east. There is still a low chance (20%) of tropical development.

**What to expect:**

- Periods of heavy tropical downpours are expected from Friday through Monday.
- Localized flooding is possible in low-lying and poor-drainage areas.
- Wind gusts could reach **25 mph**, with isolated stronger thunderstorms.

**By the numbers:**

- Tampa Bay could receive **6 to 8 inches of rain** over the next seven days, with the heaviest rainfall expected Sunday.
- Tropical development chances remain at **20%** through next week.

**The bottom line:** Flooding rain, not a named storm, remains the biggest concern for Tampa Bay as an unsettled weather pattern lingers into early next week.
