DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the center of Tropical Storm Francine was located near latitude 25.3 North, longitude 95.2 West. Francine is moving toward the northeast near 9 mph (14 km/h). A continued northeastward motion and a faster forward speed are expected later this afternoon and tonight. On the forecast track, Francine is anticipated to move away from the coast of northeastern Mexico and south Texas this afternoon, move across the northwestern Gulf of Mexico tonight, and then make landfall in Louisiana on Wednesday. After landfall, the center is expected to move into Mississippi on Wednesday night or Thursday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Strengthening is expected through Wednesday morning, and Francine will likely become a hurricane later today or tonight. Francine is expected to weaken quickly after landfall. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Francine can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header WTNT41 KNHC. 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 along the coasts of Texas, Louisiana, and Mississippi Wednesday and Wednesday night. Tropical storm conditions are possible in the watch area along the Texas coast tonight and Wednesday, and they are also possible in the watch area on the Alabama coast on Wednesday and Wednesday night. Wind gusts to tropical-storm force could occur along portions of the coasts of South Texas and northeastern Mexico this afternoon. 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. 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. 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. Please consult products from your local weather office.
