At 9:58 p.m. on Wednesday, the National Weather Service issued an updated frost advisory valid for Thursday between midnight and 8 a.m. The advisory is for Northern Cayuga as well as Wayne, Oswego and Ontario counties.

The NWS states to be ready for, “Temperatures in the low to mid 30s will result in frost formation.”

“Frost could kill sensitive outdoor vegetation if left unprotected,” comments 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.
