| Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 805pm EDT Sat July 18 2026 Issued at 805pm EDT Sat July 18 2026 Invest 91L is forecast to continue drifting northwest away from the region during the next couple of days, but the unsettled weather will persist as plenty of moisture remains across the area. For tonight we'll continue to see isolated showers and thunderstorms moving north across the area, then late tonight into early Sunday morning expect more numerous convection to develop over the eastern gulf affecting the coastal counties from Tampa Bay south. Scattered showers and thunderstorms are then expected to continue drifting north and inland across the region during the rest of Sunday. The threat of heavy rainfall near the coast remains a possibility, but the overall threat is low as the system drifts northwest away from the region. Current forecast looks on track with no adjustments needed at this time. Issued at 139pm EDT Sat July 18 2026 Unsettled weather continues as the mid level area of low pressure continues to rotate in the eastern Gulf. The Hurricane Center will continue to monitor the disturbance which currently has a 30 percent chance of development over the next 2 days and 40 percent chance over the next 7 days. Today has consisted of mostly rain showers with very lightning and only occasional gusts of more than 25 mph. Showers will continue to move onshore from the south as the afternoon continues. Some areas today have already received multiple rounds of showers, which will continue into the evening. Be cautious when out and about as the localized rainfall could lead to ponding on roads. Tomorrow is currently forecasted to be very similar to today with showers and storms off the coast moving onshore early morning. Though inland coverage will likely be less compared to the past couple of days. As the disturbance continues to slowly drift NNW over the next few days rain chances will transition further north in the CWA. A bit of uncertainty still exists in the overall forecast as we transition into next week. Much still depends on where the system in the Gulf moves and how long it takes it to do so. However, by midweek, the forecast transitions to a more typical summertime pattern as the Gulf disturbance moves far enough away to have less influence here. Marine Issued at 139pm EDT Sat July 18 2026 Less than ideal marine conditions continue as the disturbance continues to rotate in the Gulf. Periods of showers and storms likely with winds and seas increasing near storms. Winds begin to increase Sunday afternoon likely reaching cautionary to advisory levels. Elevated winds continue into early next week. Fire Weather Issued at 139pm EDT Sat July 18 2026 Fire weather concerns remain minimal as plenty of moisture remains over the area Sea Breeze Thunderstorm Regime For Sunday: 7 Sea Breeze Thunderstorm Regime For Monday: 7 For additional information on sea breeze regimes, go to: https://www.weather.gov/tbw/ThunderstormClimatology NOAA Tampa FL Office: Watches - Warnings - Advisories FL...None.
