Isaias Remnants Cause Flood Threat, Bypass Palm Beach County

Remnants of the storm formerly known as Isaias continue to pose a significant flash flooding and urban flooding threat across the Southeast. The system, which transitioned into a post-tropical cyclone, made landfall near Destin, Florida, on Friday evening, Oct. 9, 2026. By Saturday morning, Oct. 10, it was moving north, carrying heavy tropical moisture into the Tennessee Valley, Southern Appalachians, and other parts of the Southeast.

The National Hurricane Center's 4 a.m. CDT advisory on Saturday shifted its primary concern from coastal impacts to widespread rainfall and flooding farther inland. Residents in affected areas should follow local officials' instructions. The National Hurricane Center warned that heavy rainfall associated with the remnants of Isaias would spread quickly northward throughout Saturday, with some communities facing a greater threat from repeated heavy rain over the same locations.

For those cleaning up from storm damage, safety remains paramount. The National Hurricane Center advises operating generators outdoors and at least 20 feet away from homes and garages to prevent carbon monoxide poisoning. Individuals using chainsaws and power tools should exercise care and stay hydrated, especially with high humidity from Lake Okeechobee to the coast.

Travelers heading through portions of the Southeast this weekend should prepare for possible delays. Authorities recommend checking road conditions and flight status before departing, allowing extra travel time, and never attempting to drive through flooded roadways.

Palm Beach County residents should monitor local weather updates, though direct impacts from the storm's remnants are not anticipated locally. Vigilance remains wise, even as the storm bypasses the area.
