The National Weather Service issued a frost advisory at 8:03 a.m. on Sunday valid for Monday between 1 a.m. and 9 a.m. for Upper Hood River Valley.
The weather service says to anticipate, “Overnight low temperatures of 34 to 36 degrees will result in frost formation.”
“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered,” describes the weather service. “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.”
