Difference Between Freeze Warning and Frost Advisory
A freeze warning is more urgent than a frost advisory, according to the NWS.
A freeze warning prompts residents to take action. That is when temperatures dip below 32° for a long period of time. Those temperatures kill most types of commercial crops and residential plants.
A frost advisory urges residents to “be aware.” Residents should expect freezing temperatures that pose a threat to sensitive vegetation.
