Thousands without power in Florida and Alabama as Isaias moves north

At least four deaths linked to storm amid warnings of flash flooding that could stretch into Appalachians

As what was left of Hurricane Isaias moved north on Sunday, bringing moderate to heavy rainfall across the central Appalachians and the mid-Atlantic region, nearly 396,000 customers across the Florida Panhandle and southern Alabama remained without power.

Heavy rainfall associated with the storm could bring isolated flash flooding and strong wind gusts and remain a threat across the south-eastern US, especially near the southern Appalachians, according to the National Weather Service (NWS). That could bring scattered power outages and downed trees and power lines. Life-threatening surf and rip current conditions were expected to continue along the Gulf and south-eastern Atlantic coasts.
