Frigid air continued to pose a threat to California citrus groves on Saturday, and parts of the East were in a fog as temperatures rose and the snow that fell just a day earlier melted, making roads slushy and slippery.
Temperatures rose on both coasts, but the Dakotas and Mountain states stayed in a deep freeze."In the coldest areas, farmers will suffer more crop damage," Betty Reo of the National Weather Service in California said.
Daytime temperatures on Sunday could reach 60 in Los Angeles and the 50s in San Francisco, but growers could battle temperatures in the 20s in inland areas throughout the night, forecasters said.
That prompted concern over crops that escaped the first cold blitz and the future of the groves themselves. "What a lot of growers are concerned about this weekend is how much tree damage they'll have," said Tom McNair of the state Department of Food and Agriculture.
The San Joaquin Valley, the state's major orange growing area, saw its navel orange crop virtually destroyed last weekend as temperatures sank into the low 20s and the teens. The loss has been estimated at up to $288 million.
Frigid temperatures and light snow enveloped Wyoming on Saturday, with Gillette reporting the nation's low temperature - 30 degrees below zero.
Arctic air swept in by a strong north wind plunged Nebraska into a deep freeze with wind chills down to 58 below zero at Columbus.
The second winter storm that hit Washington state in two weeks battered beaches as well as inland areas and emergency officials said as many as 10 waterfront homes on Puget Sound have been destroyed or damaged by storm waves. About three dozen more were threatened by water after bulkheads were washed out.
The water damage was part of the windstorm that whipped into Washington early Friday, with frigid temperatures and some snow. One woman on Vashon Island was killed by a falling tree.
About 150,000 utility customers in western Washington were without electricity at one time.
Puget Sound Power and Light spokeswoman Heidi Dunlap said 52,000 customers were still without power Saturday morning. She said crews hoped to have service restored by Sunday night.
