Central Gulf Coast faces major flooding threat, no threat in Acadiana

Posted at 4:23 AM, Sep 15, 2020

While Acadiana isn't faced with many impacts, the central Gulf Coast is looking at a strong hurricane sitting just offshore for the better part of the day, as a strengthening Sally starts to stall off the Alabama coastline.

Sally's intensity jumped up Monday afternoon making it a strong Category 1 hurricane, and although the storm may have leveled off based on the 4:00 a.m. advisory this still remains a strong and dangerous storm.

Almost all forward movement has stopped, and landfall may not take place until early Wednesday morning, which means that flooding will be the main, serious issue with this storm with rain totals in some areas pushing beyond 20" with isolated amounts that could top 30".

This is a significant amount of rainfall and the flash flooding threat is the most immediate threat posed by this storm with widespread flooding possible from Mississippi to the western Florida panhandle.

Flooding will continue as Sally moves northward bringing a possible foot of rain to south Mississippi, central Alabama, and even north Georgia, flooding rains may spread as far north as the Carolinas through the week.

A slow moving storm such as Sally can also produce a large, prolonged storm surge and this seems to be the biggest issue that Louisiana is facing, with a surge along the eastern coast around 4-6 feet.

While Acadiana is going to be just outside of the cloud deck, mixed in with the sunshine will be some fast moving clouds and winds that will be out of the north around 10-15 mph, gusts pushing 20-30 mph through the afternoon.

This has been an extremely active tropical season and with more waves developing its worth the reminder that we still have about four weeks left in the peak of the season so we can't let our guard down yet.
