Timeline: Tracking Tuesday's severe storm, coastal flooding threat in Tampa Bay

In addition to strong to severe storms, expect some coastal flooding and high surf. Several sandbag sites are open across the area.

ST. PETERSBURG, Fla. — Strong to severe thunderstorms, including the threat of tornadoes, are possible Tuesday as Tampa Bay's roller coaster weather pattern continues this winter season.

A cold front associated with a strengthing low-pressure system is forecast to sweep through the area. At this point, the time frame of most concern will be during the afternoon and evening hours.

On land and sea, there are multiple threats: strong to severe storms with damaging winds, isolated tornadoes, large hail, heavy rainfall, coastal flooding and high surf. The area's Gulf beaches have suffered significant beach erosion from many storms, namely since Hurricane Idalia, and additional damage is possible due to the potential for a small surge.

Storm Prediction Center forecasters have highlighted the immediate Tampa Bay area under a slight risk of a threat of severe weather. That's a level two out of five, meaning that scattered severe storms are possible.

A greater risk of severe weather exists north and west of the immediate Tampa area, where the area is highlighted under an enhanced risk — a level three out of five. Numerous severe storms are possible there.

The primary threats continue to be damaging winds, isolated tornadoes and large hail.

Those storms are expected to roll in from the Gulf of Mexico during the afternoon and evening hours, first impacting Citrus and Hernando counties.

The storms will progress from the northwest to southeast, impacting the immediate Tampa Bay area from roughly 3-7 p.m. and then the southeastern portion of the viewing area after 5 p.m.

Everyone will need to stay weather-aware should some of the stronger storms turn severe.

Areas of coastal flooding are possible roughly from Tuesday afternoon through early Wednesday morning. A gale warning is in effect overnight Tuesday, and a coastal flood warning has been issued starting Tuesday.

  • Citrus County northward: 2-4 feet
  • Hernando, Pasco, Pinellas, Hillsborough, Manatee, Sarasota and Tampa Bay: 2-3 feet
  • South of Sarasota County: 1-2 feet

Before that, the Gulf will start to look angry, with waves building 6-8 feet. This high surf, combined with relentless wave action, could lead to some beach erosion.
