TAMPA, Fla. – Scattered thunderstorms could develop across the Tampa Bay area Tuesday afternoon, bringing heavy rain, lightning, and brief flooding to already steamy conditions. Afternoon highs near 94 degrees will feel closer to 105, pushing heat dangers alongside storm risks.

According to the National Weather Service in Ruskin, storms are most likely after 2 p.m. Tuesday with rainfall totals ranging from a tenth of an inch to half an inch, though higher amounts are possible in slow-moving cells. Winds will remain light, but storm outflows may cause sudden gusts and localized hazards.

Hillsborough, Pinellas, and Pasco counties should prepare for typical summer storm impacts, including slick roads on I-275, U.S. 19, and the Howard Frankland Bridge during the evening commute. Lightning will be a major concern for outdoor workers and anyone planning beach or boating activities.

The midweek pattern continues with hot, sunny mornings followed by scattered storms each afternoon through Friday. Heat index values above 100°F will remain a daily threat, particularly for vulnerable residents without reliable cooling. Officials advise limiting outdoor activity during peak heat, drinking plenty of water, and having alternate shelter ready if storms strike.

Storm chances increase toward the weekend with showers likely Saturday and Sunday. Additional advisories could be issued as rainfall totals climb.
