Four people were confirmed dead after Hurricane Isaias struck the southern United States, with two fatalities reported in Alabama and two in Florida, including victims killed when trees fell on their homes.

Power outage trackers indicated that about 500,000 customers across several states were without electricity by Saturday evening.

Isaias made landfall in Florida late on Friday with sustained winds of 105 mph (168 km/h) before being downgraded to a post‑tropical cyclone, bringing down trees and ripping roofs off buildings.

Both Alabama and Florida declared states of emergency ahead of the storm and issued mandatory evacuation orders for thousands of residents.

Rescue operations included Florida National Guard soldiers swimming to a stranded truck in a flood ditch and extracting its occupants, while officials in Alabama reported a sheriff injured by a falling tree while responding to a crash.

Additional deaths were linked to carbon‑monoxide poisoning after a generator was run in an unventilated garage, and four other occupants of the same house required hospital treatment.

Governor Ron DeSantis warned that flooding remained a “very hazardous situation,” while Alabama Governor Kay Ivey highlighted concerns about possible spinoff tornadoes and urged residents to stay informed about travel plans.

In Charleston, South Carolina, officials asked residents to remain indoors Saturday night as high tide was expected to reach 7.5 ft (2.3 m), noting that floodwater is harder to see after dark.

The National Oceanic and Atmospheric Administration warned that the Carolinas and Georgia could experience up to 10 inches (25 cm) of rain, though the storm is expected to weaken as it moves northeastward.
