Since that time, the radar structure of the storm has\ncontinued to degrade as strong vertical wind shear disrupts the\ncirculation. However, Eglin AFB (KEVX) radar data and surface\nobservations indicate damaging, gusty winds are persisting in the\nresidual northern eyewall and in a band wrapping around the western\nside of the circulation. Now that the system is farther inland and\nlosing organization, the initial intensity is lowered to 80 kt for\nthis advisory.\n \nIsaias is rapidly losing tropical characteristics, and it is \nforecast to become post-tropical within the next 12 h while it \ncontinues moving quickly northward through Alabama. Although the \nsustained surface winds associated with Isaias will quickly weaken \nnow that the storm is inland, damaging wind gusts associated with \nthe system are expected to extend well inland through Saturday, \nespecially in areas of higher terrain. Because of this, the gust \nfactors in the forecast have been slightly increased during the \nfirst 24 h. A turn toward the northeast is forecast later this \nweekend, bringing the center of the system into the Tennessee Valley \nbefore it dissipates.\n\n \nKey Messages:\n \n1. A life-threatening storm surge is expected from Dauphin Island,\nAlabama, to Suwannee, Florida where a Storm Surge Warning remains in\neffect. Residents in the warning area should continue to follow\nadvice given by local officials.\n \n2. Extremely dangerous and damaging hurricane-force winds,\nespecially in gusts, are expected over portions of the Florida\nPanhandle and southern Alabama where a Hurricane Warning remains in\neffect. Residents in these areas should have a safe room to ride out\nthe storm and prepare for long-duration power outages.\n \n3. Damaging wind gusts are likely over a large portion of the\nsoutheastern United States from western and northern Georgia and the\nsouthern Appalachians, westward over much of central and northern\nAlabama, southern middle Tennessee, and Mississippi, especially in\nareas of higher terrain. Residents should secure loose outdoor\nitems, avoid driving high-profile vehicles, prepare for power\noutages, and be aware of the potential for falling trees.\n \n4. Isaias will bring areas of heavy rainfall to the central U.S.\nGulf coast and much of the Southeast through the weekend.\nConsiderable flash and urban flooding, along with significant river\nflooding, will be possible. Landslides are also possible across the\nSouthern Appalachians.\n \n5. The tornado potential will continue through tonight. The greatest\nrisk will be east of the center, particularly across the Florida\nPanhandle into southern Georgia. This risk will continue spreading\nnorth-northeast across parts of the Southeast on Saturday.\n \n \nFORECAST POSITIONS AND MAX WINDS\n \nINIT  10/0300Z 30.8N  86.5W   80 KT  90 MPH\n 12H  10/1200Z 32.7N  86.7W   50 KT  60 MPH...POST-TROP/INLAND\n 24H  11/0000Z 34.7N  86.7W   30 KT  35 MPH...POST-TROP/INLAND\n 36H  11/1200Z 36.9N  84.4W   30 KT  35 MPH...POST-TROP/INLAND\n 48H  12/0000Z 39.0N  80.5W   25 KT  30 MPH...POST-TROP/INLAND\n 60H  12/1200Z...DISSIPATED\n \n"}
