What is the difference between a freeze watch and a freeze warning?

In its Warnings Defined page, the National Weather Service describes freeze watch and freeze warning as follows:

                                                  Freeze Watch

A Freeze Watch is issued when there is a potential for significant, widespread freezing temperatures within the next 24-36 hours.

A Freeze Watch is issued in the autumn until the end of the growing season (marked by the occurrence of first widespread freeze). The normal end of the growing season is mid to late October west of the Blue Ridge and early November east of the Blue Ridge. However, during anomalously warm autumns, the growing season may be extended past the normal end of the growing season.

A Freeze Watch is issued in the spring at the start of the growing season (when it is late enough to cause damage to new plants and crops).

                                               Freeze Warning

A Freeze Warning is issued when significant, widespread freezing temperatures are expected.

A Freeze Warning is issued in the autumn until the end of the growing season (marked by the occurrence of first widespread freeze). The normal end of the growing season is mid to late October west of the Blue Ridge and early November east of the Blue Ridge. However, during anomalously warm autumns, the growing season may be extended past the normal end of the growing season.

A Freeze Warning is issued in the spring at the start of the growing season (when it is late enough to cause damage to new plants and crops).

So a freeze watch is when there is a potential for freezing weather, a freeze warning is when it’s actually expected.

What precautions are recommended?

The National Weather Service recommends the following precautions for a freeze watch:

“Take steps now to protect tender plants from the cold. 

“To prevent freezing and possible bursting of outdoor water pipes they should

be wrapped, drained, or allowed to drip slowly. 

“Those that have in-ground sprinkler systems should drain them and cover above-

ground pipes to protect them from freezing.”
