Winter Weather May 4, 2025 – May 5, 2025 · Northwestern San Juan Mountains, Colorado
What the National Weather Service wrote
Generally 4 to 7 inches of snow fell across the area.
The wider storm
A closed low pressure system moved across the Four Corners into southwest Colorado, bringing abundant moisture and enough cold air to result in moderate to heavy snowfall across the San Juan Mountains, especially above timberline, where snowfall exceeded a foot. Very little if any snow fell elsewhere due to the concentration of dynamics with the low, with rain primarily below 9000 feet.
