The National Weather Service issued a freeze warning at 2:44 p.m. on Friday valid for Saturday between midnight and 8 a.m. for Choctaw, Washington, Clarke, Wilcox, Monroe, Conecuh, Butler, Crenshaw and Covington counties.

The weather service describes, “Sub-freezing temperatures as low as 31 degrees expected.”

“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” explains the weather service. “Take steps now to protect tender plants from the cold.”

What to do if there is a freeze watch or warning

Freeze warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be 29-32 degrees. If there is a potential for temperatures to fall into these thresholds, a freeze watch may be issued a few days ahead of time.

According to the weather service, if a freeze warning or watch is issued for your area, there is little you can do to protect plants. If you can move your sensitive plants inside, do so because the freeze will likely kill them, depending on the severity of conditions.
