Dueling winter storms have dumped snow and ice, and caused wind damage across the United States as Americans brace for dangerously cold temperatures through Valentine's Day weekend.

More than a foot of snow has already blanketed parts of Washington and Oregon as a new storm system hit the West Coast on Saturday, according to the National Weather Service.

The East Coast was hammered with more snow, ice and freezing rain as power outage numbers climbed on Saturday, the Weather Channel reported.

The outlet reported that the new winter storm system 'could be one of the heavier snow events in at least a few years in Seattle and Portland, Oregon.'

Gusty winds have already left more than 233,000 customers without power across Oregon, according to PowerOutage.us. More than 33,500 customers were left without power in Nevada.

Central Illinois was shaken by a train derailment around 5am on Saturday when 16 Union Pacific cargo cars went off the tracks near the Uptown Normal station, according to The Pantagraph. 

Temperatures were near zero at the time of the accident but it was not certain if the weather had caused it, officials told the outlet. No injuries were reported and officials said the train was not carrying hazardous materials.

As of Saturday, 40 states home to some 200 million Americans have placed winter weather alerts into effect as unseasonably cold temperatures are set to migrate as far south as Texas and Louisiana, while snow, sleet, freezing rain, and brutal wind chills will make it hazardous to leave your home in the northern half of the country.
