At least 10 weather-related deaths reported in Texas and Kansas

One woman in Texas is presumed dead after being swept away

Cold and rain expected to affect parts of Texas, Oklahoma and Kansas through Sunday

(CNN) —  

Flooding and wintry precipitation have led to at least 10 deaths in Texas and Kansas as a storm system moves across the central Plains, authorities reported.

Five people died in single-vehicle accidents in Kansas, according to Lt. Adam Winters with the state’s Highway Patrol. He said all of the accidents could be attributed to black ice or hazardous road conditions.

Flooding claimed at least three lives in the Dallas area. The victims include a man in Garland, northeast of Dallas. Benjamin Floyd, 29, was on his way to work when raging floodwaters swept his car off the road, according to CNN affiliate KTVT. He was unable to get out of his vehicle before it was submerged Friday, Garland city officials said.

The two other flooding deaths came in Johnson County, south of Fort Worth, county emergency management officials said.

The National Weather Service reported ice storms in the Texas Panhandle. Three people died in a road accident on Interstate 40 about 45 miles west of Amarillo, the weather service reported.

Driver missing; deputy holds onto tree for hours

At least one other person went missing and is presumed dead in Tarrant County. And a sheriff’s deputy who tried to save a woman was nearly swept away as well.

A vehicle carrying the 70-year-old woman was swept away by high waters there Friday morning, sheriff’s department spokesman Terry Grisham said.

During an attempt to rescue her, sheriff’s deputy Krystal Salazar got caught in the surging waters and had to hold onto a tree for two hours. The deputy was rescued.

Millions under winter weather, flood warnings

A significant section of the United States – from western Texas through Oklahoma and Kansas and into western Arkansas – has been coping with a weather system that brought rain and freezing temperatures.

Some 83,000 customers were without power in Oklahoma, according to utility company OG&E. There are numerous reports of trees down across the state. At least 400 utility crews have been deployed and they have restored power to 50,000, the company says.

An ice-storm warning and a winter weather advisory were in effect for parts of Oklahoma until noon on Sunday, according to the National Weather Service. Temperatures are expected to remain at or below freezing and accumulations of ice of up to 1 inch are possible in some areas. Freezing fog could make driving conditions even more difficult.

The National Weather Service warns that part of southeast Oklahoma and northeast Texas could still experience some flooding through Sunday evening, but some flood advisories have been allowed to expire.

In Texas, flood warnings remain in place along parts of the Trinity River in east Texas and also for sections of the Rio Grande. Water levels are expected to continue to rise along the west fork of the river through Wednesday or Thursday.

Difficult weather conditions could persist in Kansas through Sunday or even Monday. Snow accumulation of up to 5 inches is possible in some areas. In northwest Kansas, there could be gusty winds and intense snowfall.

Staying safe when the lights go out

Drivers across the region are warned to exercise caution.

“Even small accumulations of ice can be extremely dangerous to drivers and pedestrians alike,” said CNN meteorologist Rachel Aissen. “We’ve seen between ¾ to an inch of ice over the past few days with another ¼ inch of ice accumulation on the way to the Central Plains through Sunday afternoon. Ice can bring down trees and topple utility poles.”

CNN’s Joe Sutton, Sam Roth, Michael Guy, Keith Allen, Rachel Aissen and Jason Hanna contributed to this report.
