Isaias weakens after Florida landfall; flood danger remains
Isaias made landfall near Destin with 105 mph winds, then weakened to a post-tropical cyclone; flash and river flooding remain concerns across the Southeast.
Isaias came ashore near Destin, Florida, at about 8:30 p.m. CDT on October 9 with maximum sustained winds of 105 mph.
By the Weather Prediction Center’s 10 a.m. CDT advisory on October 10, the post-tropical cyclone was inland in Alabama with winds of 35 mph. [1][2][3]
The flood threat is moving inland. WPC forecasts 3–6 inches of rain, locally up to 10 inches, from northeastern Georgia into the western Carolinas and from upper coastal South Carolina into eastern North Carolina. Flash, urban and river flooding remain possible, including landslides in the southern Appalachians. Significant river flooding in the western Florida Panhandle is forecast to crest October 10–11. These are forecasts, not measured totals at every location. [1][4][7]
Use current National Weather Service alerts for a specific destination before returning or travelling through the affected region. Regional offices continue to publish flood, wind and recovery guidance; weaker sustained winds do not make flooded roads or rising rivers safe. [1][4][5][7]
