A winter storm warning remains in place for heavy snow in the Oregon and Washington Cascades through 5 a.m. Thursday.
As heavy rain and wind moved in to the lowlands of western Oregon and Southwest Washington Tuesday night and Wednesday morning, about a foot of snow fell along the Cascades above 2,500 feet.
The National Weather Service said Wednesday morning another 1 to 2 feet of snow could fall at pass level by Wednesday night.
Forecasters said a rain/snow mix was possible as low as 1,500 feet throughout the day, but that those showers were unlikely to produce any accumulating snow.
Officials have been urging people to postpone travel over the Cascade passes until weather conditions improve. They also advise people to avoid backcountry recreation as the storm moves through.
Clearer and cooler conditions could move in Thursday. But that would again bring frost concerns for much of northwestern Oregon.
A freeze watch has been issued along the Willamette Valley and the Coast Range Wednesday night through Thursday morning.
The weather service says temperatures could dip to around 30 degrees.
“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” the NWS explained.
Temperatures are expected to gradually warm this weekend.
