A freeze watch is a notice issued by the National Weather Service that announces that temperatures of 32 °F (0 °C) and below is possible in the next 48 hours. This watch is only issued during the growing season when the freezing temperature may damage or kill unharvested crops, which would end the growing season. Farmers are advised to prepare protecting their remaining crops and monitor the forecast.
