Frost Advisory
2026-10-31T09:00:00-07:00

* WHAT...Temperatures of 36 degrees or lower will result in frost formation. * WHERE...Portions of northwest and west central Oregon and southwest Washington. * WHEN...Until 9 AM PDT Saturday. * IMPACTS...Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered. * ADDITIONAL DETAILS...There is a 20-30% chance that temperatures will fall below 32 degrees, especially for locations that do not develop fog. Frost and freeze headlines are only issued through the growing season of April 1 through October 31. Therefore, frost or freeze headlines will not be issued beginning November 1, even though similar low temperatures are possible. Frost and freeze headlines will no longer be issued this growing season for the Upper Hood River Valley, southern Willamette Valley, south Washington Cascade Foothills, and north Oregon Coast Range as these locations have already experienced a hard freeze earlier in October.
