Sally's Track Shifts East Again, Southeast LA & South MS Remain At Risk


The National Hurricane Center shifted Sally's track east again Sunday night, which could see the center of the storm moving further inland closer to the Louisiana/Mississippi state line.

Part of the change was driven by the center of Sally being established to the north and east of the previous advisory.

Shifts to Sally's track are critical to determining what areas will see the largest impacts from the storm, which are expected to be near and east of Sally's center, including storm surge and heavy rainfall.

"The new NHC track forecast is slower and east of the previous one based on the initial position/motion and the latest models. However, the official forecast still lies west of the latest consensus aids, so further adjustments may be necessary overnight. While the current forecast shows landfall along the northern Gulf coast in 36 to 48 hours, the bottom line is that Sally is expected to be a slow- moving tropical cyclone near and over the northern Gulf Coast during the next few days," said a NHC forecaster.
