The National Weather Service issued a hard freeze warning at 3:42 a.m. on Friday valid for Saturday between midnight and 9 a.m. for Choctaw, Washington, Clarke, Wilcox, Monroe, Conecuh, Butler, Crenshaw and Covington counties.

The weather service adds, “Take steps now to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained, or allowed to drip slowly. Those that have in-ground sprinkler systems should drain them and cover above-ground pipes to protect them from freezing.”

What to do if there is a hard freeze watch or warning

Hard freeze warnings are issued from May to October (but can be extended if necessary). A hard freeze warning is issued when temperatures are expected to be 28 degrees or less. If there is a potential for temperatures to fall into these thresholds, a hard freeze watch may be issued a few days ahead of time.

According to the weather service, if a hard 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 kill them.
