The latest developments on the severe storms across the U.S. (all times local):
A Missouri sheriff says four soldiers from another country who were temporarily stationed at Fort Leonard Wood are among the six people who have died in flooding in the state.
Pulaski County Sheriff Ronald Long said in a statement late Sunday night that a witness saw a car drive into a flooded roadway a day earlier. It was swept downstream. First responders found two men inside the sedan who apparently had drowned, and the bodies of two other men who had been in the car were found Sunday.
Long says the victims were "international soldiers" who were temporarily stationed at the central Missouri Army base for training. They were not immediately identified, pending notification of their families by the U.S. State Department, and the statement did not give their nationalities.
A message seeking further information was left with the base's media affairs department.
Long says it's possible that a fifth person was in the car because an acquaintance of the soldiers' is missing.
The statement says the other two people who died in flooding were the occupants of a vehicle that tried to cross a flooded road.
The National Weather Service says strong weekend storms produced nine tornadoes across North Texas.
The Dallas/Fort Worth forecast office issued a statement Sunday night confirming that nine tornadoes ranging from an EF-0 to an EF-4 touched down a night earlier. Eleven people were killed.
The Weather Service says not all the tornado damage has been examined and additional surveys are planned Monday. It says the number of tornadoes may go up.
Authorities surveying damage from tornadoes in North Texas say there may be as many as 600 homes with damage in the Dallas suburb of Rowlett.
Dallas County Judge Clay Jenkins said in a statement Sunday evening that damage figures could change. He says assessments are ongoing but have been delayed due to rain.
The new figure brings the total estimate of damaged homes in Texas to as many as 1,450.
A 24-hour curfew has been established for Rowlett in the affected areas. Jenkins' statement says only residents and emergency personnel will be allowed access.
Nearby Garland was also hit by a tornado that killed eight people and left 15 injured. Police there said in a Sunday night statement that an initial search of impacted areas had concluded with no additional victims found.
Oklahoma's emergency management officials say hospitals are reporting that eight people have suffered storm-related injuries as severe weather and a blizzard pound the state. The nature of the injuries wasn't immediately known.
The Emergency Management Department says that as snow and high winds hammer western Oklahoma, warming stations have been set up at churches and other locations. The state Corporation Commission says 60,000 homes and businesses have lost electricity.
Travel is discouraged. Roads are slick and plunging temperatures will turn any water remaining on the roads into ice in western Oklahoma.

Counties statewide are reporting flooding from heavy rains.
Officials in southern Arkansas say it appears a tornado touched down in Bearden as a severe weather system rolled into the region.
There were no reports of injuries after the storm struck Sunday afternoon. Ouachita (WASH-ih-taw) County Sheriff David Norwood told the Arkansas Democrat-Gazette newspaper that a twister appeared to touch down in a four-block area along Main Street. He said the storm took roofs off buildings, uprooted trees and shattered storefront windows.
Norwood said streets into the area have been blocked to keep out looters.
Little Rock television station KATV reported that damage was also reported in Nevada County in southern Arkansas, also near Hampton, and television station KTHV reported that emergency workers had to rescue a number of people from water after heavy rains inundated northern Arkansas.
Missouri's governor has declared a state of emergency because of widespread flooding that has led to at least eight fatalities.
Gov. Jay Nixon's office said in a release Sunday that weekend flooding has led to eight deaths, dozens of water rescues and evacuations. More flooding is expected while river levels continue rising around the state.
Several roadways have also been closed because of flooding, including a section of Interstate 70 outside St. Louis.
Nixon says the state's emergency plan has been activated, allowing state agencies to coordinate with local authorities to provide emergency services.
In Pulaski County, authorities said six people died after vehicles they were in were swept away by floodwaters. Greene County authorities also said two fatalities there were associated with the recent flooding.
Nearly all of Interstate 40 in Texas, the main east-west highway through the state's Panhandle, has been shut because of a snowstorm pummeling the area.
The Texas Department of Public Safety says only a small section of the highway within Amarillo remains open. Otherwise, nearly all the 178-mile stretch is shut down.
The section west of Amarillo was closed earlier Sunday. Texas State Trooper Cindy Barkley said Sunday evening that deteriorating conditions have forced authorities to also indefinitely close the highway for about 100 miles east of Amarillo to Oklahoma.
Reports from local officials show as many as 1,000 homes in the Dallas area were damaged or destroyed by tornadoes and heavy storms that killed at least 11 people.
Texas Gov. Greg Abbott and other state officials on Sunday would not commit to an estimated number of buildings destroyed, families displaced or even casualties. They cautioned that rescue teams are still assessing the damage and sifting through toppled structures.
But numbers reported by local officials suggest a grim tally of destruction. The worst hit was Garland, where meteorologists say a powerful EF-4 tornado tore through the suburb. Wind gusts for tornadoes on that scale exceed 200 mph.
At least 600 homes were damaged in Garland and more than 100 were impacted farther to the south in Ellis County.
Garland Mayor Douglas Athas says on his official Facebook page that search teams are still looking through the rubble from an EF-4 tornado.
He said Sunday that search teams would work until they check every building and car. Utility crews were also working to restore power, and about 40 people remained in an emergency shelter.

Texas Gov. Greg Abbott is warning that the number of victims from a deadly outbreak of storms and tornadoes in the Dallas area could still rise.
Abbott made disaster declarations for four counties on Sunday following the severe weather that killed at least 11 people. He said there have been reports of as many as a dozen tornadoes around North Texas, but meteorologists were still working to confirm how many touched down.
Abbott said the state was not yet committing to a total number of casualties because rescue crews were still searching through rubble and destroyed homes.
He declared disasters in Dallas, Collin, Rockwall and Ellis counties and warned that roads across Texas remain in "perilous" condition because of plunging temperatures and continuing rainfall.
Oklahoma is seeing a range of precipitation, from blowing and drifting snow in the Panhandle to heavy, flood-inducing rains in the east part of the state.
National Weather Service meteorologist Jonathan Kurtz said it's hard to measure how much snow has fallen in the Panhandle because of 40 to 60 mph winds. That's causing 1- to 2-foot snow drifts, even with a couple inches of snow on the ground.
In central Oklahoma, including Oklahoma City, a mixture of rain, sleet and freezing rain tapered off Sunday afternoon. But Kurtz said up to four inches of snow was in the forecast for Monday.
Eastern Oklahoma saw heavy rainfall and flooding. At least 11 counties had roads and bridges that were closed due to flooding. The far northeastern Oklahoma town of Tahlequah had logged more than 9 inches of rainfall.
The body of a motorist has been found in a water-swollen creek in southwestern Missouri.

The Texas Department of Public Safety in Amarillo is strongly discouraging all travel throughout the entire Texas Panhandle because blowing and drifting snow had made the roads impassable. That's a 26-county area covering nearly 26,000 square miles.
Trooper Cindy Barkley said more than 20 motorists have been stranded by 8- to 10-foot-high snow drifts along highways U.S. 60 and U.S. 70 in Parmer County. The county is about 80 miles southwest of Amarillo along the Texas-New Mexico state line.
She said crews are trying to plow the roads but the blowing snow is making the job difficult.
Authorities also say Interstate 40 west of Amarillo for about 50 miles to the New Mexico border will remain closed through the night.
New Mexico's governor declared a state of emergency because of impassable roads. Roswell received between 14 and 18 inches of snow since Saturday afternoon, and 8 more inches were forecast.
Authorities in Alabama are attributing a second death in the state to severe weather that struck the Southeast last week.
Coffee County Coroner Robert Preachers says the body of a 22-year-old man was discovered Sunday morning. That man and a 5-year-old boy were in a vehicle that was swept away while attempting to cross a bridge near Jack, Alabama.
Preachers said the body of the boy was found Saturday.
WTVM-TV reports that four individuals from the same vehicle were rescued earlier in the same area.
The discovery raises the death toll in the Southeast from recent storms to 19. Ten people died in Mississippi, and six died in Tennessee. One person was killed in Arkansas.

Whiteout conditions and snow drifts have closed some highways in the Texas Panhandle, while historic snowfall totals are expected in nearby New Mexico.
Texas Department of Transportation spokesman Paul Braun tells the Amarillo Globe-News that crews are doing what they can to plow the drifts, but that they "go through and it blows it right back."
Parts of Interstate 40 west of Amarillo, Texas, and into Santa Rosa, New Mexico, were shut Sunday. Nearly 10,000 Excel Energy customers, most of them Amarillo, have been without power. High winds are blamed for knocking over utility poles and power lines.
Amarillo received only about 3 inches of snow overnight but high winds have caused 3- to 4-foot drifts. Forecasts are calling for another 4 to 8 inches of snow and winds gusting to 50 miles an hour. Albuquerque, New Mexico, has received about 6 inches of snow.

The car became lodged 150 to 200 feet downstream, but shortly after the first firefighter arrived on the scene it was dislodged and sank.
Cannon says dive teams recovered the car from the water several hours later and the bodies of the victims from the car.
The names of the victims were not immediately released. Cannon says the vehicle was traveling from Kentucky to Minnesota.
Witnesses say drivers appeared to abandon their cars along a Texas interstate where authorities say a tornado thrashed an area of 2 square miles outside Dallas and left at least three people dead.
Zach Shirley said Sunday that bumper-to-bumper traffic clogged Interstate 30 near an intersection where police say some cars appeared to be thrown from the road.
The 34-year-old said he spent nearly eight hours on the interstate, on which he got on after the tornado, and considered leaving his car and walking to his apartment.
Shirley said he was humbled to find out that where he lived was spared.
At least 11 people died in severe weather that damaged hundreds of homes around Dallas and shut down roads the day after Christmas.
Forecasters say the threat of severe weather is likely over for the Dallas area, where at least 11 people were killed from storms that spawned tornadoes and wreaked havoc on roadways.

Alabama Gov. Robert Bentley praised efforts to restore and improve the levee system while touring the town of Elba, which was affected by flooding.
Bentley visited the town in southern Alabama on Saturday and stopped in at Elba Elementary, where people had taken shelter from the flood waters. He says the levees are expected to withstand the river crest.
The tiny, flood-prone Alabama town was underwater in 1929, which led to the constructions of levees for protection. The city flooded again in 1990 when rising waters overwhelmed levees and again in 1998 when a levee failed under pressure from flood waters.
Bentley declared a state of emergency Friday amid widespread flash flooding that follows several days of intense weather throughout the Southeast.
