On Monday at 11:30 a.m. the National Weather Service released a frost advisory valid for Tuesday between midnight and 8 a.m. for Pueblo Vicinity/Pueblo County below 6,300 feet, Walsenburg Vicinity/Upper Huerfano River Basin below 7,500 ft, Trinidad Vicinity/Western Las Animas County below 7,500 ft and Eastern Las Animas County as well as Crowley County.

The NWS informs, “Temperatures as low as 33 degrees will result in frost formation.”

“Frost could harm sensitive outdoor vegetation. Sensitive outdoor plants may be killed if left uncovered,” explains the NWS. “Take steps now to protect tender plants from the cold.”

What to do if there is a frost advisory

Frost advisories are issued from May to October (but can be extended if necessary) when temperatures, winds, and sky cover are favorable for frost development. This is most likely to happen when the temperature is 36 degrees or less. In some cases, the frost is severe enough to end the growing season and is then referred to as a ‘killing frost’.

According to the NWS, if a frost advisory is issued for your area, cover up sensitive plants before the sun sets so that it can help retain heat near the plants, or move the plants indoors for the night, if possible.
