Environmental conditions appear conducive for some gradual development of this system, and a tropical depression could form during the latter part of the week while it moves generally north-northwestward, near the coast of southwestern Mexico and towards the Baja California Peninsula. Regardless of development, heavy rainfall is likely across coastal portions of southwestern and west-central Mexico during the next couple of days. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 7 days...medium...60 percent. $$ Forecaster Papin

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, in this case within 24 hours. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area, in this case within 24 hours.

DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Hurricane Francine was located near latitude 27.5 North, longitude 93.3 West. Francine is moving toward the northeast near 12 mph (19 km/h). A faster northeastward motion is expected today, and Francine is anticipated to make landfall in Louisiana within the warning area this afternoon or evening. After landfall, the center is expected to move northward across Mississippi on Thursday and Thursday night. Reports from Air Force Reserve and NOAA Hurricane Hunter aircraft indicate that maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Some additional strengthening is possible this morning. Francine is expected to weaken quickly after it moves inland. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 115 miles (185 km). The minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 976 mb (28.82 inches). An oil platform near the center recently reported a pressure of 977.7 mb (28.87 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Hurricane 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 this afternoon, with tropical storm conditions arriving in the warning area this morning. Hurricane conditions are possible in the hurricane watch area this afternoon and tonight. Tropical storm conditions are expected in the warning area along the coasts of Louisiana, Mississippi, and Alabama today and tonight. RAINFALL: Francine is expected to bring storm total rainfall of 4 to 8 inches, with local amounts to 12 inches across southeastern Louisiana, Mississippi, far southern Alabama, and the Florida Panhandle through Thursday night. 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... Intracoastal City, 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 Mouth of the Pearl River, LA to Ocean Springs, MS...4-6 ft Lake Pontchartrain...4-6 ft Ocean Springs, MS to MS/AL Border...3-5 ft Cameron, LA to Intracoastal City, LA...3-5 ft Lake Maurepas...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 today and tonight across parts of southeast Louisiana, southern Mississippi, southern Alabama, and the Florida Panhandle. SURF: Swells generated by Francine are affecting much of the northern and northwestern Gulf Coast, likely causing life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1000 AM CDT. $$ Forecaster Beven
