Watch the dramatic moment a woman is saved from a sinking car in the Louisiana floods


At least three people have died and thousands more were rescued after "historic" flooding swamped parts of Louisiana.

This woman - and her dog - were lucky that three men were able to rescue her when her car started sinking in Baton Rouge.

One of the men, David Phung, jumped into the water after smashing open the car window, to pull the woman out. Realising her dog was still in the car, Phung took another plunge into the murky water to retrieve the small dog.

Emergency crews have been plucking motorists from cars stranded by high water along a seven-mile stretch of the south Louisiana interstate.

Others have been pulled from inundated homes and waist-deep waters, and helpers were braced to continue the work on Sunday after conducting at least 2,000 rescues.

Louisiana governor John Bel Edwards declared a state of emergency, calling the floods "unprecedented" and "historic".

The governor toured flood-ravaged areas by helicopter later on Saturday after rivers and creeks burst their banks and warned Louisiana residents it would be too risky to venture out even after the rains start to subside.

In addition to the three confirmed deaths, Edwards said, at least one person is missing.

In the Livingston Parish city of Denham Springs, a suburb of Baton Rouge, entire shopping centres were inundated, only roofs of cars peeking above the water. And in many places, the water was still rising, with rivers not expected to crest for days.

Livingston parish sheriff Jason Ard said 2,000 people in his parish alone had been rescued, and more people awaited help.

Forecasters warned portions of central and northern Louisiana could see heavy rain into next week.
