Deadly storms wallop Gulf Coast: One dead in Mississippi as tornado rips through Louisiana and heavy rains leave floods throughout New Orleans bringing back Katrina memories

Deadly storms are battering the Gulf Coast, bringing flash floods that are drowning New Orleans streets and putting millions from Texas to the Florida panhandle. 

In Mississippi, at least one person is confirmed dead from the storms, one person is injured and dozens of properties have been damaged as the storms wreck havoc on the south. The name of the person killed has not been released. 

Downpours bringing between five to eight inches of rainfall have caused flooding in New Orleans, putting traffic to a standstill.

Heavy rain, flash flooding and severe weather threat associated with an intensifying low-pressure system is forecast to sweep across the region, according to the National Weather Service.

'We believe there will be double-digit tornadoes produced by the severe weather outbreak, and multiple tornadoes could be on the ground at the same time on Wednesday despite less-than-perfect atmospheric conditions,' AccuWeather Chief On-Air Meteorologist Bernie Rayno said.

Forecasters said strong damaging winds, which may exceed 75 mph, could wreak havoc across the region knocking down trees and poles.
