(Portland, Oregon) – The first big overnight frost advisory of the season is in effect from midnight Monday night through 9 a.m. Tuesday morning, for the northern half of the Oregon coast and most of the Washington coast, as well as the Willamette Valley, Portland / Vancouver areas and even reaching towards Seattle.

However, no such frost advisory exists for the southern Oregon coast, which will stay in the lower 40s overnight.

The National Weather Service (NWS) offices in Seattle and Portland have issued the frost advisories, saying temperatures between 32 and 36 degrees will be hitting areas from Reedsport up through Ocean Park, Washington – including Cannon Beach, Aberdeen, Long Beach, Pacific City, Newport and Florence. The frost advisory reaches into some areas near Seattle, but stays mostly in the I-5 corridor just south of there as well as the Willapa Hills. The southern Willamette Valley of Oregon, the Columbia Gorge and the Coast Range mountains will also be on the receiving end.

“Lowest temperatures, possibly nearing 30 degrees, expected in generally cooler locations like Battle Ground, Hillsboro, parts of the north Coast Range, and rural areas within the central and southern Willamette Valley,” the NWS said.

The agency said frost could kill sensitive outdoor vegetation if left uncovered.

“People in the area covered by the frost advisory are advised to harvest or protect tender vegetation,” the NWS said. “Potted plants normally left outdoors should be covered or brought inside away from the cold.”

The NWS said there is a high pressure system over the regions from the Oregon and Washington coastlines to the inland parts of Eugene, Portland and Tacoma. It admitted there is a chance for fog, which would mean higher temps than freezing, but it's a low chance. However, there's a chance some areas could see even lower temps overnight.

“And if fog and low clouds fail to develop, temperatures will be able to fall even slightly lower than what most model guidance is currently suggesting,” the NWS said.

The frost is expected to quickly dissipate once the dawn begins in the eastern skies.
