Frost Advisory vs. Freeze Watch vs. Freeze Warning: What’s the difference?

In the fall and spring, you will likely see the National Weather Service issue Freeze Watches and Warnings.

A Frost Advisory is in effect for some of the Miami Valley until Oct. 10 at 9 a.m., according to Storm Center 7 Meteorologist Austin Chaney.

While a Frost Advisory is not unusual for this time of year, a freeze would be, Chaney said.

Tune in to News Center 7 at 5 p.m. for Storm Center 7′s Chief Meteorologist Austin Chaney’s breakdown of what this advisory means for you and your crops.

Here’s the difference between the different weather advisories:

Freeze Watch

Usually issued 24 to 36 hours before temperatures are expected to drop to 32 degrees or below, according to Storm Center 7 Chief Meteorologist Austin Chaney. During the growing season, this can give you time to prepare and protect crops and outside plants.

Freeze Warning

Similar to other warnings, these alerts are letting you know the event is imminent. Widespread temperatures at or below 32 degrees are highly likely.

If temperatures are below freezing for the first time in the fall for several hours, it will also signal the end of the growing season.

Once the growing season begins in the spring, it is important to act before the temperature drops to protect plants, crops and vegetation.

When a Freeze Watch is issued, pay attention to the time frame and get ready to protect items from the cold.

For any freeze alerts, you’ll want to protect crops, outdoor plants, plumbing and even drain outdoor sprinklers the night before the cold arrives. An upgrade to a Freeze Warning can typically occur the night before the cold air arrives.

A Frost Advisory

This is issued when temperatures are expected to drop between 33-36 degrees during the growing season when clear skies and calm winds are present to allow for frost development. Frost can damage or kill sensitive vegetation and plants.
