On Wednesday at 3:43 a.m. a frost advisory was issued by the National Weather Service valid for Thursday between 2 a.m. and 10 a.m. The advisory is for Person, Forsyth, Guilford, Alamance, Orange, Durham, Davidson, Randolph, Chatham, Stanly, Montgomery, Moore, Lee and Anson counties.

The NWS states, “Temperatures as low as 34 to 37 degrees will result in frost formation.”

“Frost could harm or kill sensitive outdoor vegetation or plants if left uncovered,” adds the NWS. “Take steps 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.
