Frost Advisory issued October 15 at 2:12AM PDT until October 15 at 9:00AM PDT by NWS Portland OR

Effective: Wed October 15, 2025, 2:12 AM
Expires: Wed October 15, 2025, 9:00 AM

* WHAT...Temperatures of 32 to 36 degrees will result in frost formation. * WHERE...South Willamette Valley, North Oregon Coast Range Lowlands, East Central Willamette Valley, and Cowlitz County Lowlands. * WHEN...Until 9 AM PDT this morning. * IMPACTS...Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered. * ADDITIONAL DETAILS...The Nehalem River Valley, including Vernonia and Pittsburg, is the most likely area within the Coast Range to see temperatures fall below freezing. In those areas, there is a 70 to 90% chance of a true freeze, and a nearly 100% chance of frost, so those with agricultural interests or sensitive outdoor plants should take more substantial preventative measures.

Take steps now to protect tender outdoor plants from the cold. Consider temporarily moving outdoor potted plants indoors if they are sensitive to cold temperatures. Consider temporarily covering sensitive plants with a lightweight cotton fabric (i.e., bedsheets, thin blankets), as this will help retain heat and provide frost protection for your plants.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
