Better news for New Orleans is worse news for the Mississippi Coast and Alabama with a track shift East as far as max winds are concerned but it’s all relative and bad impacts are still expected for much of the Central Gulf Coast.
SALLY LIKELY TO PRODUCE LIFE-THREATENING STORM SURGE, HURRICANE-FORCE WINDS, AND FLASH FLOODING ALONG PORTIONS OF THE NORTHERN GULF COAST STARTING LATE TODAY...
Landfall is expected on the SE tip of Louisiana and the Mississippi Coast Tuesday as a CAT 1 with maximum sustained winds of 90 MPH near the eye.
However, model guidance is not in good agreement on the path, causing a good deal of spread for a relatively short-range forecast so DO NOT focus on the exact track or land point and remember negative impacts can and do occur outside the “cone of uncertainty”.
The bottom line is Sally is expected to be a dangerous slow-moving hurricane near the coast of southeastern Louisiana, Mississippi and Alabama during the next 2-3 days. Regardless of the exact forecast track and intensity of Sally, the slow-moving storm is expected to cause a life-threatening storm surge and freshwater flooding event.
For Atlanta rain odds start going up Wednesday with heavy rain possible from Sally here Thursday into Friday with isolated severe weather possible, especially South side, before a taste of Fall moves in Sunday and Monday with low humidity and possible lows in the 50s.
