Of the 11 confirmed dead in the Dallas area, officials said eight died in Garland. An estimated 600 buildings were damaged, most of them single-family homes, and 15 others suffered injuries, according to the city. Three others died in nearby Collin County, county officials said.
The storm system that produced the tornadoes also brought freezing temperatures into the region, closing down multiple snow-covered roads. According to CNN, Dallas had a high of 82 degrees Saturday. That dropped to 41 degrees Sunday, with freezing temperatures expected Monday.
Flooding in Missouri and Illinois claimed 13 lives Sunday, according to The Associated Press. The victims included four "international soldiers" who died after they attempted to drive on a flooded roadway. The soldiers were training at the Fort Leonard Wood Army base, Pulaski County Sheriff Ronald Long told The Associated Press.
In Oklahoma, eight people reportedly suffered injuries related to a storm system which brought blizzard conditions to the state. Authorities did not say how serious the injuries were.
The deaths and injuries come just days after dangerous storms slammed the nation's midsection on Dec. 23. Dozens of people suffered injuries after a severe weather system brought tornadoes and severe flooding to the region. Authorities said that since Dec. 23, at least 19 people have died of weather-related injuries in Alabama, Mississippi, Tennessee and Arkansas.
According to the National Weather Service, a major winter storm system will continue to bring freezing conditions to areas spanning from the Rocky Mountains to the Midwest through at least Tuesday. Weather conditions are expected to stabilize after that, although forecasters warned flooding will likely remain a lingering issue.
