On Tuesday at 9:21 a.m. the NWS Portland OR released a frost advisory valid from 11 p.m. until Wednesday 9 a.m. for Inner Vancouver Metro.

The NWS informs, "Temperatures as low as 34 to 36 degrees will result in frost formation."

"Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered," explains the NWS. "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."

This advisory is in effect until Wednesday at 9 a.m.

What to do if there is a frost advisory

Frost advisories are issued from May to October (but can be extended if necessary) when temperatures, winds, and sky cover are favorable for frost development. This is most likely to happen when the temperature is 36 degrees or less. In some cases, the frost is severe enough to end the growing season and is then referred to as a 'killing frost'.

According to the NWS, if a frost advisory is issued for your area, cover up sensitive plants before the sun sets so that it can help retain heat near the plants, or move the plants indoors for the night, if possible.
