Widespread damage was reported around Slidell, Louisiana, after a tornado with winds of at least around 100 mph tore through the state on Wednesday.

NEW ORLEANS – A Flash Flood Emergency was issued for the city of New Orleans as part of a deadly severe weather outbreak that dropped torrential rains across the lower Mississippi Valley and Gulf Coast and even spawned a few damaging tornadoes.

At least two people died in the storms in Mississippi, while dozens were left injured in various events across the Gulf Coast.

Widespread flooding swamped the New Orleans metro area Wednesday afternoon as several inches of rain drenched the city in just hours, sometimes falling at a rate of 1-3 inches per hour. The 6.24 inches that fell at New Orleans Int'l Airport was the third-wettest April day in their records and accumulated in just seven hours. 

Emergency management reported numerous roads and underpasses in and around New Orleans were underwater and impassible from the late morning into the afternoon.

Dramatic videos showed first responders working to block off flooded roads to prevent vehicles from driving on them and getting submerged.

Possible tornado causes building collapse in Katy, Texas

Powerful thunderstorms and a possible tornado tore across the Houston suburb of Katy, Texas, early Wednesday morning. FOX 26 Reporter Shelby Rose joined FOX Weather from Katy where a building collapsed during the severe weather.

"If it was a tornado, it dropped down right in the middle of this parking lot of this strip center and went away," FOX 26 Houston Reporter Shelby Rose said. "I mean, there is no damage anywhere surrounding us. Not even to some small trees."

The NWS in Houston said the tornado lasted just 1 2/3 miles but destroyed a Firestone tire store when the tornadic winds blew out west-facing windows in the lobby. Survey teams said the building's air conditioning unit was launched from the south to the north across the parking lot, while the debris field from the collapsed building was strewn more in an east-west direction. 

While there were no people inside that building at the time, there were people inside a sports bar that also received damage.

Luckily, the tornado quickly weakened as it exited the strip mall to EF-0 status, still lasting another 1.5 miles but only leaving some tree limbs broken and minor property damage. 

Another tornado touched down in Chunchula, Alabama, damaging a home.

Severe weather outbreak was likely a serial derecho

Analysis from the FOX Weather Center indicates the severe weather outbreak could be classified as a serial derecho.

For meteorologists to classify a windstorm as a derecho – from the Spanish word for "straight" – the swath of straight-line wind damage it causes must cover a distance of at least 400 miles and include wind gusts over 58 mph along most of its path, as well as several, well-separated 75-mph or higher gusts, according to NOAA's Storm Prediction Center.

WHAT IS A DERECHO?

The storms Wednesday spawned damaging wind reports for over 650 miles, spanning from near Houston to the Florida Panhandle.

The storm eventually passed off to the east Thursday night, drenching the rest of the Gulf Coast and leading to new Flash Flood Emergencies as the storm reached Tallahassee.
