At 11:18 a.m. Tuesday, the National Weather Service issued a frost watch effective Thursday between 2 a.m. and 10 a.m. for Eastern Curry County, Josephine County and Jackson County.

The weather service adds: “Temperatures below 0°C can drop to 28 degrees.”

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

Freeze monitoring or warning – that’s what it means

Frost warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be between 29 and 32 degrees. If there is a risk of temperatures falling below these thresholds, a frost watch may be issued a few days in advance.

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