"Temperatures have warmed above freezing," says the NWS Pendleton OR.

The warning is in effect until 9 a.m.

Freeze watch or warning - this is what it means

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.
