On Wednesday at 1:40 p.m. the NWS Eureka CA issued an updated freeze warning valid for Thursday between 2 a.m. and 8 a.m. The warning is for Southern Trinity, Northeastern Interior Mendocino and Northeastern Trinity as well as Lake County.

The NWS informs, "Sub-freezing temperatures as low as 30 degrees expected."

"Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing," describes the NWS. "Take steps now to protect tender plants from the cold."

This warning is in effect until Thursday at 8 a.m.

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 NWS, 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.
