On Tuesday at 9:52 a.m. an updated freeze warning was issued by the National Weather Service in effect until 10 a.m. for Larimer County below 6,000 feet/Northwest Weld County, Boulder/Jefferson counties below 6,000 feet/West Broomfield County and North Douglas County below 6,000 feet/Denver/West Adams and Arapahoe counties/East Broomfield County.

“Lows between 19 and 25 degrees are expected Tuesday night into Wednesday morning,” comments the NWS. “Some areas within these zones have already experienced a killing freeze, particularly Weld County, Longmont and vicinity, and the northeast Denver metro. However, many of the more urban locations remain susceptible, and are expected to see a killing freeze Tuesday night.”

“Frost and freeze conditions could kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing,” explains the NWS. “Take steps now to protect tender plants from the cold.”

What to do if there is a freeze watch or warning

Freeze warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be 29-32 degrees. If there is a potential for temperatures to fall into these thresholds, a freeze watch may be issued a few days ahead of time.

According to the NWS, if a freeze warning or watch is issued for your area, there is little you can do to protect plants. If you can move your sensitive plants inside, do so because the freeze will likely kill them, depending on the severity of conditions.
