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. 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 during the next 48 hours.

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 Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

HAZARDS AFFECTING LAND:

WIND: Hurricane conditions are expected within the hurricane warning area on Wednesday. with tropical storm conditions arriving in the warning area by early Wednesday.

Tropical storm conditions are expected in the warning area in Mexico and south Texas for the next several hours. Tropical storm conditions are possible within the watch area along the northeastern coast of Mexico for the next few hours. Tropical Storm conditions are expected in the warning area along the Louisiana and Mississippi coasts Wednesday and Wednesday night. Tropical storm conditions are also possible along portions of the Texas coast in the watch area today and tonight, and are possible in the watch area on the Alabama coast on Wednesday and Wednesday night.

RAINFALL: Francine is expected to bring storm total rainfall of 4 to 8 inches, with local amounts to 12 inches across much of Louisiana and Mississippi through Friday morning. This rainfall could lead to considerable flash and urban flooding.

For a complete depiction of forecast rainfall associated with Francine, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at1.shtml? Rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at1.shtml? Ero.

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…

Rockefeller Wildlife Refuge, LA to Port Fourchon, LA…5-10 ft Vermilion Bay…5-10 ft Port Fourchon, LA to Mouth of the Mississippi River, LA…4-7 ft Sabine Pass, TX to Rockefeller Wildlife Refuge, LA…3-5 ft Pointe a la Hache, LA to MS/AL Border…3-5 ft Lake Pontchartrain…3-5 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. Storm surge is not expected to pose a threat to the risk reduction system levees. However, there may be some overtopping of local levees.

Minor coastal flooding is possible along the coast of Mexico in areas of onshore winds.

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.

TORNADOES: A few tornadoes are possible Wednesday morning through Wednesday night over near-coastal areas of Louisiana, Mississippi, Alabama, and the Florida Panhandle.

SURF: Swells generated by Francine are affecting portions of the coast of northeastern Mexico and southern Texas. These swells are expected to spread across the northwestern and northern Gulf of Mexico coastline during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions.
