For\na depiction of areas at risk, please see the National Weather\nService Storm Surge Watch/Warning Graphic, available at\nhurricanes.gov. This is a life-threatening situation. Persons\nlocated within these areas should take all necessary actions to\nprotect life and property from rising water and the potential for\nother dangerous conditions. Promptly follow evacuation and other\ninstructions from local officials.\n \nA Tropical Storm Warning means that tropical storm conditions are\nexpected somewhere within the warning area.\n \nFor storm information specific to your area, including possible\ninland watches and warnings, please monitor products issued by your\nlocal National Weather Service forecast office.\n \n \nDISCUSSION AND OUTLOOK\n----------------------\nAt 100 AM CDT (0600 UTC), the center of Post-Tropical Cyclone Isaias\nwas located near latitude 31.5 North, longitude 86.5 West. The\npost-tropical cyclone is moving toward the north near 20 mph (31\nkm/h), and this general motion is expected today. A motion toward \nthe north-northeast or northeast is forecast on Sunday. On the \nforecast track, Isaias is expected to move across Alabama and into \nthe Tennessee Valley later today and Sunday.\n \nMaximum sustained winds have decreased to near 65 mph (100 km/h) \nwith higher gusts.  Continued weakening is expected, but Isaias is\nexpected to continue producing gusty winds well inland before \nweakening below gale force later today.\n \nTropical-storm-force winds extend outward up to 160 miles (260 km)\nfrom the center.\n \nThe estimated minimum central pressure is 1000 mb (29.53 inches).\n \n \nHAZARDS AFFECTING LAND\n----------------------\nKey messages for Isaias can be found in the Tropical Cyclone\nDiscussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.\n \nSTORM SURGE: The combination of a dangerous storm surge and the\ntide will cause normally dry areas near the coast to be flooded by\nrising waters moving inland from the shoreline. The water could\nreach the following heights above ground somewhere in the indicated\nareas if the peak surge occurs at the time of high tide...\n \nSanta Rosa/Okaloosa County Line, FL to Suwannee River, FL...2-4 ft\n \nThe deepest water will occur along the immediate coast in areas of\nonshore winds, where the surge will be accompanied by large and\ndangerous waves. Surge-related flooding depends on the relative\ntiming of the surge and the tidal cycle, and can vary greatly over\nshort distances. For information specific to your area, please see\nproducts issued by your local National Weather Service forecast\noffice.\n \nFor a complete depiction of areas at risk of storm surge inundation,\nplease see the National Weather Service Peak Storm Surge Graphic,\navailable at hurricanes.gov/graphics_at4.shtml?peakSurge.\n \nWIND: Tropical storm conditions are ongoing in the tropical storm \nwarning area for the next several hours.\n \nRAINFALL: Through the weekend, Isaias is expected to produce \nrainfall amounts of 4 to 8 inches across southern Alabama, the \nFlorida Panhandle and Big Bend, and southwest Georgia. Localized\ntotals up to 15 inches are possible, particularly within banding\nacross the Florida Panhandle and Big Bend.\n \nAcross much of the remainder of the Southeast, rainfall amounts of 2\nto 5 inches are expected.  Localized higher amounts up to 10 inches\nare possible, especially across the Southern Appalachians and\ncoastal Carolinas.\n \nFlash, urban, and river flooding is possible across the region, with\nconsiderable impacts likely across much of southern Alabama and the\nFlorida Panhandle into southwestern Georgia. Considerable flash\nflooding and landslides are also possible across the Southern\nAppalachians.\n \nFor a complete depiction of forecast rainfall associated with\nIsaias, please see the National Weather Service Storm Total Rainfall\nGraphic available at\nhurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk\ngraphic at hurricanes.gov/graphics_at4.shtml?ero.\n \nTORNADOES: A risk for tornadoes will persist overnight across the\nFlorida Panhandle and north Florida into southern Georgia. The\ntornado threat will continue today across parts of the Florida\nPanhandle, Georgia, and the Carolinas.\n \nSURF: Swells from Isaias are affecting much of the Gulf coasts of\nthe United States, Mexico, and western Cuba. These swells are\nlikely to cause life-threatening surf and rip current conditions.\nPlease consult products from your local weather office.\n \nA depiction of rip current risk for the United States can be found\nat: hurricanes.gov/graphics_at4.shtml?ripCurrents\n \n \nNEXT ADVISORY\n-------------\nNext complete advisory at 400 AM CDT.\n \n"}
