| Area Forecast Discussion National Weather Service Tallahassee FL 610am EDT Thu Oct 8 2026 .SHORT TERM... (Today and Tonight) Issued at 252am EDT Thu Oct 8 2026 Today is the day to make your preparations for Isaias before conditions deteoriate on Friday. Mainly dry conditions are expected for today with the exception of the big bend coast where some showers will persist. Highs will generally be in the low to mid 80s with overnight lows in the mid 60s to near 70. Long Term (Friday through Wednesday) Issued at 252am EDT Thu Oct 8 2026 Isaias will have a significant impact on the local area on Friday into Saturday with improving conditions on Sunday. Dry weather is expected starting Monday through the middle of next week, which will be favorable for cleanup efforts. 1) Flooding rain: Soggy conditions across the region from recent rainfall will make the area more sensitive to flooding from additional heavy rainfall from Isaias. Forecast rainfall totals of 3 to 7 inches are expected across much of the area, with isolated amounts near 10 inches possible. These values would likely cause scattered flash flooding and some river flooding. Considerable flash flooding is possible in areas where training feeder bands set up, most likely across the western half of the area. 2) Damaging winds: The wind field with Isaias will expand as it nears the coast, and wet soils from previous rain will allow for more trees to come down with slightly lower wind speeds than typical. Thus, significant impacts from tree and power line damage are expected within the tropical storm and hurricane warning areas. 3) Tornadoes: Several tornadoes are expected across the area with the feeder bands as they move ashore, mainly from late Friday into Saturday. 4) Storm Surge: Inundation values of 5 to 7 feet above ground level (AGL) are possible across the coastal Panhandle to Indian Pass, 4 to 6 feet AGL from Indian Pass to Steinhatchee, and 2 to 4 feet AGL from Steinhatchee to Yankeetown. Marine Issued at 252am EDT Thu Oct 8 2026 Isaias will bring significant impacts to the area with tropical storm and hurricane conditions ramping up on Friday into Saturday. The hurricane will rapidly exit the area on Saturday, and conditions will start to improve on Sunday and especially Monday. Fire Weather Issued at 252am EDT Thu Oct 8 2026 There are no major fire weather concerns with Isaias approaching and plenty of rain on the way. Hydrology Issued at 252am EDT Thu Oct 8 2026 Isaias is expected to move across the northern Gulf Coast late this week into the weekend, bringing 3 to 7 inches of rainfall to the area with isolated amounts near 10 inches possible. Considerable flash flooding is expected in localized areas where training feeder bands set up. Elsewhere, isolated to scattered instances of flash flooding are expected, especially given saturated conditions from recent heavy rainfall. Areas generally near and west of the Apalachicola and Flint Rivers have a slightly higher heavy rainfall risk than areas east. River flooding is also possible, especially on the smaller creeks and streams.
