Storms are being blamed for at least one death. One person was killed Saturday night and another left in critical condition after a tornado hit Cisco, Texas, a rural farming and ranch area about 100 miles west of Fort Worth. The National Weather Service rated the tornado as an EF-3, with winds ranging from 136 to 165 mph.
Residents of Delmont were being asked to leave for safety reasons on Sunday after a tornado struck the small South Dakota town. About 20 buildings were damaged and the town had no water, power or phone service, South Dakota Department of Public Safety spokeswoman Kristi Turman said. There were no serious injuries.
The National Weather Service said a likely tornado caused damage near the North Texas town of Denton.

Flooding followed heavy rains and snow during the past week in Colorado.
In northeastern Colorado, an ambulance transferring a patient was swept off a Morgan County road by swift-moving water about 5 a.m. Sunday.
The ambulance was swept about 100 yards down the normally-dry Antelope Creek, turned 180-degrees and became caught on the stream bank just long enough for five people including the crew and patient to get out of the rear of the ambulance without injury, Firefighter Travis Bailey of the Wiggins Rural Fire Protection District said.
The ambulance, however, didn't make it.
"It's now sitting in about 6 feet of water. It's marooned. You can only see the top of it," he said.
Major flood warnings were issued Sunday for the South Platte River in parts of Weld, Morgan, Washington and Logan counties. Forecasters urged people to be prepared to evacuate, but no evacuations were ordered.

By Sunday afternoon, the storm had been downgraded to a tropical depression as it moved north of Myrtle Beach. The storm's maximum sustained winds were 35 mph.
Ana is expected to move north Sunday, turn to the northeast and pick up speed, forecasters said.
In Southport, N.C., Shirley Haithcox said a few limbs were down and he Cape Fear River was choppy because of the winds. "I guess you could say it's more of a nuisance because it's just so wet. So far, it hasn't damaged anything," Haithcox said.
