Frost advisory for Santa Clarita and San Fernando Valleys for Sunday — temperatures at a low of 35

Calabasas/Agoura Hills, Santa Ynez Valley and Ojai Valley are included in a frost advisory released by the National Weather Service on Saturday at 7:48 p.m. The advisory is valid for Sunday, Feb. 22 between midnight and 9 a.m.

The NWS Los Angeles/Oxnard CA states to prepare for, “Temperatures as low as 35 degrees will result in frost formation.”

“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered,” the NWS said. “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.
