(CNN) — Flooding has led to three deaths in the Dallas area after severe rains, authorities said Saturday — part of a wintry storm system that is leaving tens of thousands without power as it hits the central Plains to the north.

More than 7 inches of rain have fallen in the Dallas area from Friday into Saturday morning, leading to widespread flooding, and more rain is expected into Sunday.

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 WFAA. 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.

Driver missing; sheriff’s deputy holds on to tree for hours

At least one other person was missing and presumed dead in Tarrant County, a situation that led to the dramatic rescue of a sheriff’s deputy who got caught up in floodwaters while trying to save her.

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

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

Emergency crews in Texas were on standby Saturday in case the rain led to more flooding. Rescue boats were ready in Johnson County on Friday night, and crews from the Texas Department of Transportation were checking high-water hot spots and other places vulnerable to flooding, according to WFAA.

Meanwhile in Oklahoma, state Department of Transportation crews continue to treat highways and bridges with salt and sand in several affected areas, according to CNN affiliate KFOR. Drivers are advised to be alert to downed limbs and power lines in roadways.

Millions under winter weather, ice storm warnings

The rains affecting Dallas were part of a system that was leaving dangerously icy travel conditions to west and north Saturday, from western Texas through Oklahoma and Kansas. Freezing rain was expected from Amarillo, Texas, to just west of Kansas City.

As of Saturday morning, ice storms have left nearly 60,000 people in Oklahoma City without power, according to power company OG&E’s Twitter account. Downed power lines have been reported in nearly every community across central Oklahoma, CNN affiliate KOCO said.

About 2.5 million people were under an ice storm warning Saturday morning, including residents in the Oklahoma City area.

Another 4 million people were under a winter weather advisory or freezing rain advisory.

“If temps continue to fall, we’ll definitely see some refreezing of the wet roads,” Oklahoma Department of Transportation spokesman Cody Boyd told KFOR. The roadways will “become ice overnight.”

“We had to let off the acceleration, because we all got to sliding,” truck driver Field Barnes told KFOR on Friday of the drive he was making west of Oklahoma City.

Flash flood watches were in effect for 11 million people from Texas to Missouri. One, for much of North Texas, is scheduled to expire at 6 a.m. Sunday.
