Some coastal flooding is likely as the storm surge is forecast to be 3+ feet in the St. Louis Bay, Pass Christian, Long Beach and Gulfport areas of Mississippi in addition to the heavy rains.
The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide:
- Shell Beach to Dauphin Island…3 to 5 ft.
- Navarre Florida to Dauphin Island, including Mobile Bay…2 to 4 ft.
- Shell Beach to the Mouth of Mississippi River…2 to 4 ft.
- Mouth of the Mississippi River to the Louisiana-Texas border…1 to 2 ft.
The National Weather Service has issued a storm surge warning from Shell Beach, Louisiana, to Dauphin Island. A storm surge watch has been issued from West of Shell Beach to the mouth of the Mississippi River and from East of Dauphin Island to Navarre.
A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials.
A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations.
Winds are expected to be strongest at the Mississippi – Alabama border where forecasts show a high probability of sustained winds reaching tropical storm force (up to 39 mph.) Areas along the Mississippi coast could see maximum sustained winds of up to 58 mph and guts higher than that.
