Hurricane Isaias killed four people and left 670,000 residents without power in the southeastern U.S.

Hurricane Isaias caused at least four deaths and left approximately 670,000 residents without electricity after it hit Florida’s coast on Saturday. The storm, which was Category 2 at the time of impact, later transformed into a post-tropical cyclone, but continued to generate dangerous conditions in the southeastern United States.

Two of the deaths were caused by trees falling onto homes. Authorities continued to warn of storm surges, flash floods, powerful wind gusts and tornadoes in the Florida Panhandle, Georgia and the Carolinas.

At noon, approximately 420,000 customers in Florida, 190,000 in Alabama, 43,000 in Georgia and 17,000 in Mississippi were without power. In Florida, restoring power was declared a priority, and approximately 16,000 technicians were ready to intervene. Several roads in Houston County, Alabama, were closed because of downed trees and power lines.

Pensacola Airport was damaged and remained closed to commercial flights. Emergency declarations were approved in Florida and Alabama, while the Department of Energy authorized an exchange of up to four million barrels of crude oil from the Strategic Reserve to offset supply disruptions.
