More power outages and travel delays are being reported as Winter Storm Cara continues to pummel the central United States, and the threat of additional outages and disruption looms as the powerful storm is predicted to generate additional ice and snow throughout the weekend.

Parts of New Mexico, Texas, Oklahoma and Kansas were under ice storm warnings from the National Weather Service on Friday. Flood warnings were in effect in portions of Texas, Kansas, Oklahoma, Arkansas and Missouri. Numerous other advisories and warnings had been issued.

The Weather Channel predicts that 21 states will be subjected to snow, sleet or freezing rain by the time Cara dissipates. Cara is moving slower than usual because of a pattern in the jet stream.

The storm began dropping snow on the Pacific Northwest on Tuesday. The Weather Channel’s forecasts indicate Cara’s energy could linger over eastern states until the middle of next week, and caution that rainfall in warmer regions ahead of the snow could trigger flash flooding.

On Friday, meteorologists were concerned about an ice storm that was developing in a swath that stretched from eastern New Mexico into northern Texas, central Oklahoma, southeastern Kansas and northwestern Missouri. That’s where the icy precipitation was expected to accumulate the most and last the longest, according to meteorologists at AccuWeather.com.

They warned of a half inch of ice building up on certain exposed surfaces. AccuWeather’s senior vice president of enterprise solutions, Mike Smith, told the organization’s website that the storm could also cause “significant power failures” in certain parts of Oklahoma and Texas.

The Weather Channel reported a quarter of an inch had already built up in Woodward, Oklahoma, on Friday morning, and the entire town of Rockwell City, Iowa, was without power.

The snow has also led to travel delays and accidents throughout the country.

The Minnesota State Patrol had reported 139 crashes as of 9 p.m. Wednesday night, according to WCCO in Minneapolis. At least one of those accidents was fatal and 33 of them caused injuries.

Some motorists became trapped in the snow on roads in southern California, the California Highway Patrol told the Los Angeles Times. Officials in Idaho reported cars slid off roads there.

According to The Weather Channel, the heaviest snowfall was reported in Nevada, where an estimated 25 inches fell near Deeth. More than 20 inches of snow were reported in parts of California and Oregon, and 14 inches were reported Buhl, Idaho and Sinks Canyon, Wyoming.

It wasn’t just the snow that was accumulating, as an NBC News report indicated Dallas-Fort Worth broke its all-time rainfall record with Cara’s precipitation early Friday morning. More than 53 inches of rain have fallen there since the start of the year.
