WATCH: Aerial Footage Shows Devastating Flooding in Louisiana

The record level flooding that has hit Louisiana has killed six people, forced thousands out of their homes, left motorists stranded across a major interstate and forced authorities to rescue some 20,000 people. Authorities worked through the night to rescue motorists stranded on I-12 with a break in the weather finally allowing for major progress on the rescue.

In an updated forecast discussion Monday, the National Weather Service said the historic river flooding continues over areas between Baton Rouge and Lake Maurepas. The relief is that the current weather has returned to a more typical summer pattern as the storm moves west. Scattered and isolated showers and thunderstorms will continue with temperatures reaching close to 90 degrees.

At the request of Gov. John Bel Edwards, FEMA has declared a major disaster declaration for East Baton Rouge, Livingston, St. Helena and Tangipahoa parishes. Those living in the affected parishes can register for FEMA assistance online, while those not in a parish that is under a disaster declaration can register with FEMA by phone.
