Twelve of the injured have been hospitalized, Belle County Judge David Blackburn said, adding that he believed everyone was responsible.
Two confirmed tornadoes have landed in Bell County, the state’s central region, the National Weather Service’s Storm Forecasting Center said.
On Tuesday, calls to 911 reported a reversal around 5:40 p.m. local time, Blackburn said. The tornado crossed the county line from neighboring Williamson County, traveling seven miles on land, he added.
Damage ranges from downed power lines and trees to leveling buildings that have been reduced to rubble in many areas, Blackburn said.
“I think he showed up pretty quickly,” Blackburn said. “The extent of the damage is significant. At least at this point, no deaths have been reported in themselves.”
Tuesday brought a double-threat storm system that delivered at least eight tornadoes, mainly in Texas and Iowa, as well as heavy snow to many states, including Dakota, Montana and Minnesota.
Parts of Dakota and Montana had blizzard warnings, and forecasters warned of treacherous white conditions on the roads.
Heavy snow closed more than 500 miles of Interstate 94 between Montana and North Dakota.
A mountainous area near Pony, Montana, recorded 47 inches of snow in a 24-hour period, according to the NWS. Many other parts of the state were covered in more than a meter of snow.
In North Dakota, more than a foot of snow has been reported in several places, including Grand Forks and Rockford, according to NWS.
“We have blizzards in April, but such an intensity is quite rare,” Jeff Shield, a meteorologist at the Bismarck Meteorological Office, told CNN early Tuesday. “The last noticeable level of intensity was April 4-7, 1997.
Heavy weather threatens 97 million on Wednesday
As the system moves east, it produces three threats – destructive winds, tornadoes and hail.
More than 97 million people were under some sort of severe weather warning on Wednesday, stretching from Texas and Louisiana to Missouri and Illinois.
The most significant threats are expected in Memphis, Tennessee; Evansville, Indiana; Jonesboro. Pine Bluff and Little Rock in Arkansas; Owensboro, Kentucky – where more than 5 million people are at moderate risk (level 4 of 5). These cities could see strong winds, tornadoes, and heavy hail.
In general, strong thunderstorms could affect much of the lower and middle parts of the Mississippi Valley in the Midwest, as well as the lower Ohio Valley, the Storm Forecasting Center said.
Elsewhere in parts of Montana, North Dakota and northern Minnesota, there may also be heavy snow on Wednesday. The snow is expected to end on Thursday, followed by extremely low temperatures.
“The lows will drop for teenagers in West North Dakota at night, and with strong winds the cold from the wind will be in single digits from above to below zero, quite cool for mid-April,” said the office of the Bismarck Weather Service.
On Friday, high temperatures are likely to reach 20, which is about 30 degrees below normal. The region could break records for low maximum temperatures.
