One death was reported in Brazoria County, Texas. A fourth was reported in Iredell County, North Carolina, after a tree fell on a vehicle and killed a man on Landis Highway Sunday morning.
Confirmed tornadoes
Saturday’s storms produced more than 20 preliminary and confirmed tornadoes in Texas, Louisiana, Mississippi, Alabama and Georgia, causing structural damage.
On Sunday evening, the National Weather Service released preliminary strength estimates for several tornadoes that struck Texas on Saturday. They included a severe vortex in the Porter Heights area of Montgomery County, which reached an estimated EF3 on a strength scale of 0-5, with EF5 being the most powerful, the weather service said in a statement.
The preliminary reading of EF3 means the tornado most likely had winds of at least 130 mph.
Another preliminary EF3 tornado raced along Highway 124 in Chambers County, the weather service said. It also noted EF2 damage on the ground in the county, although it was unclear if it was from the same tornado.
The weather service rated a vortex that rotated nearly nine miles in Brazoria County as a preliminary EF2, indicating it was “strong,” with sustained winds of at least 110 mph. The weather service confirmed one death and said an unspecified number of people were injured and an elementary school suffered “maximum damage,” the statement said.
Weaker tornadoes included a preliminary EF1 and an EF0 in Galveston County, the weather service said. The former requires sustained winds of at least 80 mph; the latter, which reportedly landed at Bayshore Park, had to produce winds of at least 60 mph (100 km/h) to make EF0.
The stronger of the two twisters was only 800 feet on the ground but caused “significant roof damage to a few homes,” the weather service said.
Investigations are ongoing and preliminary assessments for other vortices are expected to be released in the coming days.
Another EF1 tornado was confirmed in Lamar County, Alabama This is reported by the National Weather Service. Additional storm surveys will take place Monday in Shelby, St. Clair, Lowndes, Montgomery and Macon counties.

Widespread damage
Videos on social media showed downed trees in Bayou Chicot, Louisiana, and downed power lines and structural damage to homes in Conroe, Texas.
Texas Lt. Gov. Dan Patrick said more than 300 first responders and 180 resources, including search and rescue teams, have been deployed to support the state’s storm response.
“Texas state agencies are working hard to help their fellow Texans and have begun assessing the damage,” Patrick, who is acting governor while Gov. Greg Abbott is out of state, said in a statement.
The serious threat is decreasing
On Sunday, the storm system worked its way east and passed over 20 million people from the eastern Gulf Coast to the Carolinas are at risk of extreme weather.
The severe risk decreased as the storm front moved north and east and appeared to produce fewer severe thunderstorms. The weather bureau in Lexington, Kentucky, said in its forecast that small hail and gusty winds were possible until early Monday.
More than 10,200 flights within, to or from the United States were delayed and nearly 500 were canceled as of Sunday evening, according to U.S. State Department figures. FlightAware.com.
The weekend of unusual weather, which occurs more often in the spring and fall during the summer, is partly the result of the collision of cold air with the rare December warmth.
High temperatures in parts of Texas could cross the 90-degree mark early in the week, the weather service said. The Southeast could see high temperatures in the 70s even as cool air is sucked in behind that tornado-sparking front, federal forecasters said.
