Frost and Freeze Advisories Issued for Pacific Northwest
Large portions of Oregon and Washington are under freeze and frost advisories, with the National Weather Service (NWS) forecasting cold temperatures from Friday night into Saturday morning. The advisories extend to both inland and some coastal regions, raising concerns about potential impacts on sensitive vegetation and outdoor plumbing.
Details on the Frost Advisory
The NWS has placed a Frost Advisory in effect from midnight Friday through 9 a.m. Saturday for parts of northwest and west-central Oregon and southwest Washington. While urban areas and the immediate coastline are less likely to experience severe conditions, rural sections of the Willamette Valley, inland Washington, and the Coast Range are expected to see temperatures dropping around or below the freezing point.
Impacted Areas and Cities
Regions included under the Frost Advisory are the Clatsop County Coast, Tillamook County Coast, Central Coast of Oregon, Central Oregon Coast Range, Lower Columbia River, several Portland Metro areas, Cascade Foothills of Marion and Linn counties, Lane County Cascade Foothills, Willapa Hills, Cowlitz County Lowlands, and parts of Vancouver. Cities such as Portland, Lake Oswego, Lincoln City, Astoria, Newport, Vancouver, and Seaside are among those affected. The NWS advises residents to protect sensitive plants by using lightweight coverings or bringing potted vegetation indoors.
End of Season for Frost and Freeze Headlines
The NWS noted that frost and freeze warnings are only issued during the growing season, which runs from April 1 to October 31. After November 1, frost and freeze headlines will not be issued, even if similar weather conditions continue. Some specific areas, such as the Upper Hood River Valley, southern Willamette Valley, south Washington Cascade Foothills, and north Oregon Coast Range, are not receiving further alerts this year after experiencing a hard freeze earlier in October.
Freeze Watch for Region and Additional Threats
A Freeze Watch remains in effect for late Friday night through Saturday morning in parts of northwest Oregon and southwest Washington. Regions under the Freeze Watch include the Clackamas County Cascade Foothills, East Central and West Central Willamette Valley, Tualatin Valley, Central Oregon Coast Range Lowlands, and North Clark County Lowlands. Expected lows could dip to 32 degrees or below, increasing the risk to unprotected plants and outdoor plumbing systems.
A separate Freeze Watch covers Washington’s Middle Chehalis River Valley and the lowlands of Lewis and southern Thurston counties, including cities such as Rochester, Fords Prairie, Chehalis, and Grand Mound. These areas may experience overnight lows between 26 and 30 degrees, with the NWS warning of potential for damaging frost and freeze conditions.
Precautions and Next Steps
Residents in the affected zones are encouraged to cover or bring in sensitive vegetation and prepare outdoor plumbing for the cold. The NWS will not issue further frost or freeze warnings after October 31, so ongoing vigilance is recommended as seasonal low temperatures continue.
