9/14 – Rob Knight’s “HURRICANE SALLY” Update/Forecast
All eyes continue to be on Tropical Storm Sally about 100 miles east-southeast of the mouth of the Mississippi River. Still quite a bit of uncertainty regarding landfall, as it will be highly dependent on exactly when Sally begins a northward turn, which hasn’t occurred yet. In addition, the system is going to be moving very slowly over the next couple of days.
Significant storm surge, wind and rainfall/flooding threats are expected with Sally. Rainfall totals of 8 to 16 inches, with isolated amounts to 24 inches are possible to the right of the track of Sally. The current track would put the heaviest rainfall on the Mississippi coast. Again, this is highly dependent on the exact track. These amounts would certainly lead to flash flooding, potentially life-threatening, as well as river flooding. Current expectations are for landfall to occur Tuesday afternoon or Tuesday night, moving north of the area by Wednesday afternoon.
