From the National Weather Service:
Good morning,
The latest weather briefing concerning multiple weather hazards associated with the passage of a warm front, then developing non-tropical low pressure over the Gulf of Mexico, is attached. This briefing will also post shortly to https://www.weather.gov/media/key/DSS/dssbrief_land.pdf
Bottom Line:
A multi-hazard weather event is beginning to develop across the eastern Gulf of Mexico and Florida region. Due the extended duration of potential impacts and varying degrees of confidence, this brief will be segmented into:
- A relatively high confidence for heavy, potentially flooding rainfall developing Thursday and continuing through Saturday night. Strong northeast to east winds sustained 25 to 30 mph with frequent gusts 35 to 40 mph, especially Thursday night and Saturday. Localized coastal flooding is possible Thursday night and Friday in the Card Sound/Barnes Sound area.
- A continuing high confidence for heavy rainfall and flooding potential, and a lower confidence for severe thunderstorm wind gust and tornado potential Friday night and Saturday.
- A lower confidence potential for coastal flooding Gulfside and Bayside due to increasing westerly winds developing Sunday and continuing into Monday.
Details on the level of the weather threats and timing are contained in the attached briefing. The next briefing is scheduled for release around 11:00 am Thursday.
