DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Storm Gordon was located near latitude 30.8 North, longitude 88.8 West. Gordon is moving toward the northwest near 14 mph (22 km/h). A northwestward motion with some decrease in forward speed is expected over the next couple of days. On the forecast track, the center of Gordon will move across the lower Mississippi Valley through Wednesday. A turn toward the north-northwest and north is forecast to occur on Friday. Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Continued rapid weakening is expected while the system moves over land, and Gordon is forecast to become a tropical depression later this morning. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. A wind gust to 43 mph (69 km/h) was recently reported at Mobile Airport. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- 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... Mouth of the Mississippi River to Pascagoula...1 to 3 ft. Pascagoula to the Alabama/Florida Border including Mobile Bay...2 to 4 ft. Alabama/Florida Border to Navarre, Florida...1 to 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 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. RAINFALL: Gordon is expected to produce total rain accumulations of 4 to 8 inches over the western Florida Panhandle, southwest Alabama, southern and central Mississippi, northeastern Louisiana, and southern Arkansas, with isolated maximum amounts of 12 inches through late Thursday. This rainfall will cause flash flooding across portions of these areas. WIND: Tropical storm conditions will continue during the next few hours within portions of the warning area. TORNADOES: A couple of tornadoes are possible near the coasts of Alabama and the western Florida Panhandle. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Pasch
