DALLAS (AP) -- Tornadoes swept through the Dallas area after dark on Saturday leaving substantial damage and at least four people dead from traffic accidents during the storm, the latest in a succession of freakish winter weather events across the country.
The Texas tornadoes followed days of tumultuous weather in the Southeast including unusual winter tornadoes that left 18 people dead there over the Christmas holiday period.
National Weather Service Meteorologist Anthony Bain in Fort Worth said several tornadoes touched down in the Dallas area, although the full extent of damage would not be known until daylight Sunday.
Local TV showed homes with roofs blown away, vehicles mangled or turned upside down, a severely damaged church, fallen trees and debris strewn across neighborhoods. The damage stretched over about a 40-mile-long area from 20 miles south of Dallas to northeast of the city.
Joe Harn, police spokesman for Garland, about 20 miles northeast of Dallas, said the four people were killed in vehicle accidents during the massive storm, but it's unclear if all four were in the same vehicle or how they died.
"I do know that they are going house to house and going through the apartments looking for people," Harn said.
In the town of Rowlett near Garland, police spokesman Det. Cruz Hernandez said several people were injured although the exact number was not immediately clear. Two families were barricaded in their homes and first responders were trying to get them out.
The twisters - accompanied by torrential rain, wind and some hail - were part of a weather system that could produce major flooding from north Texas through eastern Oklahoma, eastern Kansas, western Arkansas and parts of Missouri.
Passengers waiting for flights at Love Field, a major Dallas airport, were moved away from windows during the storm. Flights were temporarily halted from Dallas-Fort Worth International Airport. The Dallas Mavericks NBA game was delayed about half an hour because of the storm.
On the other side of Texas, a snowstorm accompanied by plunging temperatures was expected to leave up to 16 inches of snow in West Texas and much of New Mexico through Sunday evening, according to NWS meteorologist Brendon Rubin-Oster in College Park, Maryland.
"It's going to be quite dangerous for anyone exposed to these elements," Rubin-Oster said.
Snow fell as the Sun Bowl college football game between Miami and Washington State Saturday afternoon in the Mexican border city of in El Paso, which is forecast to get 6 to 8 inches of snow from the storm.
In the Southeast, two more deaths linked to weather were reported Saturday in Mississippi, bringing that state's death toll from severe weather over Christmas to 10. Late Saturday, one death was reported in Alabama.
Flash flooding closed roads across Alabama and trapped motorists in rapidly rising waters.
Ranager Tyler and his son waded into flood water Christmas night and used rope to pull an 11-year-old boy out after his family's car was swept away near Pinson, about 15 miles northeast of Birmingham.
"The little boy was hanging on to the back of the car," Tyler said Saturday.
The family's car was overcome with flood water and ended up in a ditch near Tyler's Pinson home. The rushing water separated the family as they got out of the car, he said. The boy was later reunited with his family.
Mississippi Emergency Management Agency spokesman Greg Flynn said 56 injuries were reported. In a statement, Flynn said preliminary damage estimates show 241 homes were destroyed or severely damaged.
More than 400 homes in total were affected, he said. Severe storms are forecast for Sunday night through Monday as a strong cold front pushes through. Tornadoes are possible, and residents are asked to remain alert.
The flooding is the result of heavy downpours that have thrashed the southeastern U.S. since Wednesday, bringing record rainfalls in some areas. Four inches of rain walloped the city of Mobile, Alabama, on Wednesday - smashing the previous record of 2.2 inches set in 1990.
Six people were killed in Tennessee, including three who were found in a car submerged in a creek, according to the Columbia Police Department. The Tennessee Emergency Management Agency said Saturday that authorities were monitoring areas for possible flooding.
One person died in Arkansas, and dozens of homes were damaged or destroyed.
Better weather was forecast for the Southeast. Temperatures in the eastern third of the country could set numerous records highs Sunday, Rubin-Oster said. Washington, D.C., could see a record daily temperature of 73 degrees, New York City 65 -which would break a record of more than 50 years -and Orlando, Florida could tie a record of 86 degrees set in 1921.
