JACKSON, Miss. – Just days after tornadoes struck parts of the South, the region is once again facing the threat of dangerous storms that have already spawned other hurricanes.

On Saturday morning, several tornadoes again raged in southeast Texas on the outskirts of Houston and caused significant damage.

Drone video showed several damaged buildings in Porter Heights, north of Houston.

Observers reported that several mobile homes were hit and the tornado caused significant damage to a brick home and the East Montgomery Fire Department building, according to the National Weather Service office in Houston.

An image taken near the Houston suburb of Katy showed a funnel floating above the ground.

Spotters reported damage to a mobile home park near Noel Lane.

Additional reports of tornadoes occurred near the cities of Cypress and Liverpool. According to NWS Houston, several homes were damaged between Alvin and Liverpool.

A tornado was also reported Saturday morning near Oretta, Louisiana, where officials said the twister was captured on video.

Current situation

Forecasters have urged millions from Texas to the Carolinas and south to Florida to remain vigilant this weekend.

Storms have already begun Saturday morning from Texas to Mississippi, and several tornado and severe thunderstorm warnings have also been issued.

Watches were also issued for parts of at least five states.

A watch means conditions are favorable for severe weather to develop and people should prepare to take action if a warning is issued.

Widespread tornadoes are possible on Saturday

A Level 4 severe weather zone has been declared for Saturday, covering parts of Alabama, Arkansas, Louisiana, Mississippi and Texas. A Level 3 zone stretches from Texas to Florida.

“This just has a classic tornado day feel,” FOX Weather Storm Tracker Brandon Copic said early Saturday afternoon from southern Mississippi. “You can just feel it in the air, what the environment is like. And it was definitely an eerie feeling this morning and the amount of sunshine we saw – the downpours are definitely very worrying.”

Large hail, damaging winds and tornadoes are expected with any severe storms developing late Saturday morning into Saturday night. Some strong tornadoes, i.e. EF-2 or higher, are also possible. But forecasters fear some tornadoes could be even stronger.

“These discrete supercells ahead of this line, which will develop across East Texas into the afternoon, pose a risk for strong tornadoes, and not just EF-2,” said FOX weather meteorologist Jane Minar. “We were able to see… several long-range tornadoes of type EF-3 or larger.”

People living in these areas should review their tornado safety plans and ensure they have a reliable way to receive weather warnings. Download the FOX Weather app to get alerts based on your location and 3D radar to track storms.

Danger of severe weather moves east on Sunday

The dangerous storms will move east through Sunday, with the worst weather expected in a band stretching from Virginia to Florida. Tornadoes, damaging winds and hail are possible with any severe storms that develop in this zone.
