A frost advisory was released by the National Weather Service on Wednesday at 12:42 p.m. valid for Thursday between 2 a.m. and 9 a.m. for North Bay Interior Valleys.

The NWS says to prepare for, “Temperatures as low as 35 degrees will result in frost formation.”

“Cold conditions will be hazardous to sensitive populations such as unhoused individuals. Cold conditions can lead to hypothermia with prolonged exposure,” adds the NWS. “Take steps now to protect tender plants from the cold.”

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.
