Minus 32 Wind Chill in Brighton, December 22, 2022: Why a Fast Drop Splits Pipes
The National Weather Service wind chill report for December 22, 2022 listed Brighton, Colorado at about minus 32 degrees in the early morning. An arctic front had come through. Denver dropped to a low of minus 24, and the temperature at DIA fell 37 degrees in one hour.
This was a weather event, not a plumbing failure. Wind chill describes how cold exposed skin feels, not the temperature inside a pipe. Still, a fast drop like that is what catches exposed pipes in garages, crawl spaces and outside walls.
The lesson: know where your shutoff is before the front arrives. If a pipe splits, frozen pipe repair starts with shutting the water off. Then call the line and describe what you see.
