A chance of showers will be possible this morning in the vicinity of a cold front moving across the region. The cold front will push southeast of Florida by this evening and strong high pressure builds into the area from the northwest in the wake of this front. This will produce gusty northerly winds reaching Small Craft Advisory level by this afternoon and continuing through Saturday morning. This has warranted the issuance of a Small Craft Advisory for all the eastern Gulf waters including Tampa Bay and Charlotte Harbor. Decreasing winds to around 10-15 knots expected on Sunday and into next week. The next cold front brings showers for next Tuesday, but winds and seas should remain below headline criteria. && $$ GMZ830-271930- Tampa Bay waters- 136 AM EST Thu Nov 27 2025 ...SMALL CRAFT ADVISORY IN EFFECT FROM 1 PM EST THIS AFTERNOON THROUGH SATURDAY MORNING... .TODAY...North winds 5 to 10 knots, increasing to around 20 knots by the afternoon.
