The National Weather Service issued an updated frost advisory at 5:20 p.m. on Saturday valid for Sunday between 4 a.m. and 8 a.m. for Dillon, Florence, Marion, Williamsburg, Georgetown and Horry counties.
The weather service describes, “Temperatures as low as 36 degrees will result in frost formation.”
“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered,” describes the weather service. “Take steps now to protect tender plants from the cold.”
This advisory is in effect until Sunday at 8 a.m.
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 weather service, 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.
