990 FXUS62 KTAE 100534 AFDTAE Area Forecast Discussion National Weather Service Tallahassee FL 134 AM EDT Wed Oct 10 2018 .AVIATION [Through 06Z Thursday]... Conditions will deteriorate from south to north across area terminals this morning into the afternoon today as Hurricane Michael moves closer to the panhandle coast. Winds will increase with lowering ceilings and bands of convection moving onshore today with gradual improvement late in the TAF period. && .PREV DISCUSSION [426 PM EDT]... .SHORT TERM [Tonight Through Thursday Night]... Key Points... 1. Hurricane Michael is expected to make landfall as a major hurricane along the Florida Panhandle or western Big Bend on Wednesday. Conditions will begin to deteriorate late tonight into early Wednesday. 2. The greatest threats include the danger of life threatening storm surge along the Florida Panhandle and Big Bend coastlines and damaging winds that will result in widespread power outages that may last days to even more than a week in some areas. In addition, localized flash flooding and a few tornadoes are possible. 3. With evacuation orders in effect, follow the guidance of local emergency management and evacuate if told to do so. The Wednesday and Wednesday night time frame is when the greatest impacts (potentially catastrophic) from Hurricane Michael will be felt across the area. Michael continues to strengthen as it moves northward and enters the southern Gulf of Mexico and is forecast to be a major hurricane at landfall. Life threatening storm surge, downed trees and power lines causing widespread and long lasting power outages, structural damage impacting homes and businesses, isolated tornadoes, and flash flooding are all expected. Your hurricane preparations should be completed today. .LONG TERM [Friday Through Tuesday]... A dry stretch of weather is forecast Friday through Sunday, along with a cooler and drier air mass. Temperatures will be more seasonable with highs in the low to mid 80s and lows in the mid 50s to mid 60s. For Monday through Tuesday, a complex pattern sets up which leads to uncertainty in the sensible weather details. The area will reside between a cold front approaching from the west, high pressure nosing down the eastern seaboard, and greater subtropical moisture to the east. This leads to the potential for increased shower activity during this period. .MARINE... Hurricane Michael is expected to have a major impact on the area. Hurricane conditions are expected with the worst conditions expected on Wednesday. .FIRE WEATHER... Red flag conditions are not expected for the next several days. .HYDROLOGY... Given the track and intensity of Hurricane Michael, widespread rainfall totals of 4 to 8 inches with isolated 12 inch amounts are possible. The highest of these totals will be in the Florida panhandle and western Big Bend counties along and to the east of the track of Michael. These rainfall amounts will result in flash flooding. Current river conditions are below normal levels. With the anticipated rainfall, expect some of our river basins to rise above flood stage. This appears most likely in the Ochlockonee River basin, where there's potential that a couple of sites reach near moderate flood levels. .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
