Denver, Colorado – Colorado enters the heart of winter Sunday as the Winter Solstice arrives, marking the shortest day of the year and the beginning of the state’s coldest and most prolonged stretch, a critical time for homeowners and drivers preparing for holiday travel and early January conditions.
With extended overnight darkness and repeated freeze-thaw cycles, risks to pipes, vehicles, and daily commutes increase sharply across the Front Range, mountain communities, and high-elevation valleys. Temperatures often drop well below freezing overnight, even when daytime sunshine brings brief warming, creating conditions that can stress plumbing systems and quickly turn roadways icy after sunset.
According to the National Weather Service Boulder, overnight lows are expected to remain near or below freezing through the weekend and into early next week, particularly in mountain and foothill areas. This pattern significantly increases the risk of frozen or burst pipes, especially in older homes, cabins, garages, and properties with exposed plumbing.
State and local officials urge residents to insulate exposed pipes in basements, crawl spaces, and exterior walls, keep thermostats set no lower than 55 degrees, and allow faucets to drip slightly during the coldest nights. Cabinets under sinks along exterior walls should be left open to help warm air circulate. Open flames should never be used to thaw frozen pipes; officials recommend space heaters or hair dryers used cautiously and never left unattended.
Drivers heading into late December and early January travel—especially those crossing mountain passes—are encouraged to prepare vehicles now. Officials recommend checking battery strength, tire tread, antifreeze levels, and windshield washer fluid rated for subzero temperatures, along with carrying emergency kits that include blankets, food, water, and phone chargers.
Cold weather remains Colorado’s most persistent winter hazard through January, particularly in higher elevations where overnight refreezing is common. Officials note that additional weather advisories and travel alerts may be issued as New Year’s travel increases and winter storms move through the region.
