DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Storm Francine was located near latitude 24.4 North, longitude 96.2 West. Francine is moving toward the north-northwest near 5 mph (7 km/h). A slow north-northwest motion is expected through this morning, followed by a turn to the northeast with an increase in forward speed. On the forecast track, Francine is anticipated to be just offshore of the coasts of northeastern Mexico and southern Texas through today, and make landfall in Louisiana on Wednesday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Francine will likely become a hurricane today, with significant strengthening expected before it reaches the coast. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 992 mb (29.30 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. Hurricane conditions are possible in the hurricane watch area on Wednesday, with tropical storm conditions expected by Wednesday morning within the warning areas. Tropical storm conditions are expected in the warning area in Mexico and south Texas through this afternoon. Tropical storm conditions are possible within the watch area along the northeastern coast of Mexico for the next several hours. 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 in eastern Louisiana on Wednesday. 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... Cameron, 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 High Island, TX to Cameron, LA...3-5 ft Mouth of the Mississippi River, LA to MS/AL Border...2-4 ft Lake Pontchartrain and Lake Maurepas...2-4 ft Mouth of the Rio Grande, TX to High Island, TX...1-3 ft Galveston Bay...1-3 ft MS/AL Border to AL/FL Border...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. 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. 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. Please consult products from your local weather office.
