As of 900PM Central Time, Hurricane Nate has generated a widespread 2-4 ft storm surge along the Gulf Coast. Peak surge levels have now exceeded 4 ft at Shell Beach, Louisiana, and continue to rise in this location.
Expect maximum storm surge levels to reach 4-7 ft east of the Mississippi River in SE Louisiana, as well as the Mississippi Coast.
These storm surge levels do NOT include normal astronomical tides, which are peaking this weekend in the region due to the full moon. These king tides are among the highest tides of the year, and are not included in these storm surge observations.
Therefore, give a buffer for additional flooding because tides would normally be unusually high even if there wasn't a hurricane in the Gulf.
