HAZARDS AFFECTING LAND
STORM SURGE: 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…
Intracoastal City to Shell Beach…3 to 6 ft
Shell Beach to Biloxi MS…3 to 5 ft
Lake Pontchartrain…3 to 5 ft
Biloxi MS to the Mississippi/Alabama border…1 to 3 ft
Lake Maurepas…1 to 3 ft
Surge-related flooding depends on the relative timing of the surge and the tidal cycle and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.
RAINFALL: Barry is expected to produce total rain accumulations of 10 to 20 inches over south-central Louisiana and southwest Mississippi, with isolated maximum amounts of 25 inches. Across the remainder of the Lower Mississippi Valley, total rain accumulations of 4 to 8 inches are expected, with isolated maximum amounts of 12 inches. This rainfall is expected to lead to dangerous, life-threatening flooding.
WIND: Tropical storm conditions are occurring across portions of the Tropical Storm Warning area, and these conditions should persist through Sunday morning. Wind gusts to tropical-storm force in squalls are possible along portions of the coasts of Mississippi, Alabama, and the western Florida Panhandle through tonight.
TORNADOES: Isolated tornadoes will be possible through tonight cross southwest Alabama, southern Mississippi, and southeast Louisiana.
