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 Hurricane Warning means that hurricane conditions are expected\nsomewhere within the warning area. \n \nA Tropical Storm Warning means that tropical storm conditions are\nexpected somewhere within the warning area.\n \nA Storm Surge Watch means there is a possibility of life-\nthreatening inundation, from rising water moving inland from the\ncoastline.

Isaias is moving\ntoward the north near 17 mph (28 km/h), and this general motion is \nexpected to continue through Saturday. A north-northeastward to \nnortheastward motion is forecast on Sunday. On the forecast track, \nIsaias is expected to make landfall along the coast of the western \nFlorida Panhandle this evening. The center is then expected to move \nacross Alabama and into the Tennessee Valley Saturday and Sunday.\n \nMaximum sustained winds are near 115 mph (185 km/h) with higher\ngusts.  Isaias is a category 3 hurricane on the Saffir-Simpson\nHurricane Wind Scale.  Little change in strength is expected before \nIsaias makes landfall this evening. Weakening is expected to begin \ntonight after landfall, and Isaias is forecast to become \npost-tropical on Saturday.\n \nHurricane-force winds extend outward up to 35 miles (55 km) from the\ncenter and tropical-storm-force winds extend outward up to 205 miles\n(335 km). A sustained wind of 46 mph (74 km/h) with a gust to 58 \nmph (93 km/h) was recently measured at Fair Point Light 2 near Gulf \nBreeze, Florida. A wind gust to 56 mph (90 km/h) was reported at \nthe Pensacola Naval Air Station.\n \nThe estimated minimum central pressure is 959 mb (28.32 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 \nAL/FL Border to Grayton Beach, FL...6-9 ft\nGrayton Beach, FL to Indian Pass, FL...4-7 ft\nIndian Pass, FL to Steinhatchee River, FL...4-6 ft\nDauphin Island, AL to AL/FL Border...4-6 ft\nSteinhatchee River, FL to Suwannee River, FL...3-5 ft\nMouth of the Mississippi River, LA to Dauphin Island, AL...3-5 ft\nLower Mobile Bay...3-5 ft\nSuwannee River, FL to Yankeetown, FL...2-4 ft\nUpper Mobile Bay...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: Within the Hurricane Warning area, tropical storm conditions\nare now occurring, and hurricane conditions are expected this\nevening into early Saturday. Hurricane-force winds are expected to\nspread inland as far as 100 miles from the coast into southern\nAlabama. Tropical storm conditions are also occurring in the\ntropical storm warning areas.\n \nRAINFALL:  From Friday through the weekend, Isaias is expected to \nproduce rainfall amounts of 4 to 8 inches across southern Alabama, \nthe Florida 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: The risk for tornadoes this afternoon in the Florida \nPanhandle will continue into this evening and tonight across the \nFlorida Panhandle, southeast Alabama, and southern Georgia. The \ntornado threat will continue Saturday across parts of eastern \nAlabama, the Florida Panhandle, 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 intermediate advisory at 700 PM CDT.\nNext complete advisory at 1000 PM CDT.\n \n"}
