What is a freeze warning?
A freeze warning means temperatures at or below 32°F are expected during the growing season, enough to kill crops and sensitive plants. Since 2024-2025 it also covers the colder nights that had a hard freeze warning of their own. A warning means the hazard is happening, about to happen, or very likely: act now to protect people and property. AreaZine's counts include the hard freeze warnings issued before the change.
