Freeze warning

A freeze warning is a warning issued by the National Weather Service when sub-freezing temperatures are expected in the next 36 hours. This can occur with or without frost. When a freeze warning is issued in the fall, that will usually signify the end of the growing season, as sub-freezing temperatures will usually kill all remaining crops. Farmers and gardeners should take action to protect or harvest their herbaceous plants if a freeze warning is issued. A freeze warning is issued several hours after a freeze watch if a freeze continues to be expected.
