The National Weather Service released an updated frost advisory at 9:13 p.m. on Monday valid for Tuesday between 2 a.m. and 8 a.m. The advisory is for Niagara, Orleans and Monroe counties.

The NWS adds to prepare for, “Temperatures in the mid and upper 30s will result in frost formation.”

“Frost could kill sensitive outdoor vegetation if left unprotected,” explains the NWS. “Take steps now to protect tender plants from the cold.”

Frost advisory – this is what it means

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.
