More than 200,000 people across Louisiana still didn't have any power five days after Hurricane Isaac ravaged the state. Thousands of evacuees remained at shelters or bunked with friends or relatives.

As residents in Louisiana, Mississippi and Arkansas began surveying the damage to their homes, remnants of Isaac pushed their way north, spinning off tornadoes in southeast Missouri and threatening flash-flooding in parts of Tennessee and Kentucky.

On Sunday morning nearly 265,000 customers in Louisiana, 13,000 in Mississippi and 7,300 in Arkansas remained without power, according to The Weather Channel.

Isaac was the first hurricane to strike the United States this year and it hit the New Orleans area almost exactly seven years after Hurricane Katrina devastated the city, causing an estimated 1,800 deaths.
