Sept. 13, 12:15 p.m.
- A Tropical Storm Warning remains in effect for coastal northwest Florida.
- A Flash Flood Watch remains in effect for the western Florida panhandle through Thursday.
- Tropical Storm Sally will continue to move west northwest through Monday, before turning north on Monday night into Tuesday.
- Strengthening is forecast and the system is forecast to become a hurricane on Monday.
- A hurricane is forecast to make landfall early Tuesday somewhere across southeast Louisiana to coastal Mississippi.
- The system will slow significantly as it approaches the coast and this will likely be a prolonged event especially in regard to heavy rainfall, potential surge, and dangerous surf.
- This has the potential to be an extensive rainfall and flooding event even with the storm making landfall to the west of the local area.
- Be ready for short-fused changes to the track and intensity forecast. An eastward shift in the track still cannot be ruled out.
- The next full update will be at approximately 6 p.m. today.
Tropical Storm Wind Speed Probabilities
- Mainly tropical storm force gusts possible along the immediate coast with rain bands moving in Monday into Tuesday morning.
Storm Sure Watch/Warning
- Based on the latest track, storm surge values of one to three feet in northwest Florida. This level does NOT trigger any evacuations.
- The highest water levels will likely be on Tuesday morning around the time of high tide.
- Surf heights will build to 8 to 12 feet along all gulf beaches in the western Florida panhandle beginning late tonight.
- Although no evacuations are anticipated at this time, you should ALWAYS KNOW YOUR ZONE. Visit Santa Rosa County's Know Your Zone app for evacuation zone information.
Forecast Storm Total Rainfall/Flooding Potential
- Expect that roads which typically flood will flood. Turn around, don't drown. It is not possible to determine if a flooded roadway is covering a potentially deadly washout.
- Public works crews will be monitoring for flooding. Do not drive around or move any barricades.
- View closed roads here.
- This system has the potential to bring riverine flooding later this week. If you live on the river, be prepared for the possibility Wed. into Thurs. or Fri.
- Given the expected slow movement of the system, heavy rainfall appears likely and extensive flooding will be possible.
- Rainfall totals of 6-12” with localized amounts of 20” are possible across coastal northwest with 3-6” of rain with locally higher amounts possible further inland.
