* WHAT...Temperatures of 36 degrees or lower will result in frost formation. * WHERE...Portions of northwest and west central Oregon and southwest Washington. * WHEN...From midnight Friday Night to 9 AM PDT Saturday. * IMPACTS...Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered. * ADDITIONAL DETAILS...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. Additionally, 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.

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.
