Issuance Policy
Freeze Warning/Watches and Frost Advisories will be issued during the beginning and the ending of the growing season.
Frost Advisory
A Frost Advisory is issued when temperatures are forecast to be in the 33°F to 36°F range with good radiation conditions. Typically, frost can occur when the temperature falls below 36°F, especially in rural areas. It is a localized phenomenon and can be quite variable across a small area.
Freeze Warning/Watch
A Freeze Warning is issued when minimum temperatures are forecast to be 32°F or less. Frost becomes more widespread when the temperature falls below 32°F with some freeze possible. A Freeze Watch may be issued a few days ahead of time if the potential exists for temperatures to fall into these thresholds.
Hard Freeze Warning/Watch
A Hard Freeze Warning is issued when temperatures are expected to be 28°F or less. A Hard Freeze Watch may be issued a few days ahead of time if the potential exists for temperatures to fall into these thresholds.
