WIND: Tropical storm conditions are expected within the warning area during the next few hours. 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... Matagorda, TX to the Mouth of the Mississippi River, LA...1-3 ft The deepest water will occur along the immediate coast near and to the east of the landfall location, where the surge will be accompanied by large and dangerous waves. 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. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at1.shtml?peakSurge.

Please consult products from your local weather office. A depiction of rip current risk for the United States can be found at: hurricanes.gov/graphics_at1.shtml?ripCurrents TORNADO: A few tornadoes are possible late tonight across southeast Louisiana and southern Mississippi, and tomorrow into parts of Alabama, Georgia, and the Florida Panhandle.
