The\npost-tropical cyclone is moving toward the north near 14 mph (22\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 35 mph (55 km/h) \nwith higher gusts. Slow weakening is forecast today, and Isaias is \nforecast to dissipate on Sunday.\n\nThe estimated minimum central pressure is 1002 mb (29.59 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 \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 this morning through \nthis afternoon across parts of the eastern Florida Panhandle, \nGeorgia, and the Carolinas.\n\nSTORM SURGE: Water levels will continue to recede along the Florida\nGulf Coast throughout the day.\n \nSURF: Swells from Isaias will continue to affect much of the \nGulf coasts of the United States, Mexico, and western Cuba this \nweekend. These swells are likely to cause life-threatening surf and \nrip current conditions. Please consult products from your local \nweather 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-------------\nThis is the last public advisory issued by the National Hurricane\nCenter on this system.
