Record Western US Snow Drought Heightens Risks of Spring Water Shortages and Wildfires

Western United States – An extraordinary snow drought fueled by persistent warmth and scant precipitation has plunged mountain snow reserves to historic lows across much of the region, casting a shadow over spring water availability and fire preparedness.[1][2]

Snow Accumulation Falters Under Record Heat

January delivered a double blow of dryness and abnormal warmth that stifled snow buildup throughout the West. Precipitation fell well short of norms in most states, with many areas receiving half or less of average amounts. Temperatures soared, prompting rain in places where snow typically dominates and melting what little accumulated.[3]

At least 67 weather stations logged their hottest December through early February periods on record. Snow cover dwindled to roughly 155,000 square miles by early February, far below the typical 460,000 square miles that rivals the combined area of several large states. Mark Serreze, director of the National Snow and Ice Data Center, described the weather pattern as unprecedented in its stubborn hold: “I have not seen a winter like this before… This pattern that we’re in is so darned persistent.”[2]

States Report Deepest Snow Deficits in Decades

Oregon led the crisis with a statewide average snow water equivalent of just 2.9 inches, the lowest on record and nearly 30% below the prior benchmark from 2015. Jason Gerlich, a NOAA regional drought coordinator, highlighted the severity: Oregon’s snowpack stood “not only record low, but 30% lower than the previous record.”[1][3]

Colorado and Utah matched this dismal mark, posting their slimmest statewide snowpacks since records began in the early 1980s. Nearly every Western state hosted stations with record-low snow water equivalent readings. Critical basins suffered too, including the Upper Colorado River, Deschutes, Yakima, Rio Grande, and Humboldt, where levels hovered at 50% or less of medians.[1]

• Oregon: 86% of stations in snow drought; Cascade Range and Blue Mountains at record lows.
• Colorado: 95% of stations affected; Upper Colorado Basin at record low average.
• Utah: 80% of stations; statewide record low.
• Washington: 82% of stations; Olympic Mountains fully depleted.
• Nevada: 77% impacted; Humboldt Basin at 32% of median.

Water Supplies Teeter on the Edge

Diminished snowpack translates directly to reduced spring and summer runoff, straining reservoirs and rivers that millions depend on. Forecasts for the Upper Colorado River Basin predict inflows to Lake Powell at only 60% of normal for the water year, with April-July volumes at 43%. Agriculture, urban centers, and hydropower face mounting pressure as basins like the Yakima hold reservoirs at partial capacity despite recent rains.[1]

Daniel Swain of the University of California’s Water Resources Institute called the situation in the Colorado Basin “a pretty big problem.” Prolonged cool, wet weather offers the only hope, though experts deem median peak snowpack levels unlikely this season. Salt Lake City endured 327 days without an inch of snow, the longest dry spell since the 1890s.[3]

Wildfire Dangers Rise with Early Thaw

Scant snow elevates fire risks by baring soils and vegetation to spring sun sooner than usual. Daniel McEvoy of the Western Regional Climate Center warned that early melt accelerates drying: “Snow disappearing earlier than average leaves the ground exposed to warmer weather in the spring and summer that dries soils and vegetation quicker.”[2]

Meteorologists at the National Interagency Fire Center anticipate an earlier-than-normal 2026 season unless substantial March snow arrives. Leftover fuels from 2025’s fires compound the threat across the Mountain West. Lower elevations already lack protective cover, priming landscapes for ignition.[4]

Recreation sectors reeled too, with ski operations curtailed and winter tourism battered. While California fared better thanks to December deluges, the broader West confronts cascading effects tied to fossil fuel-driven warming.

As the West awaits potential relief from incoming storms, the stark snow deficit underscores urgent needs for adaptive water management and fire mitigation. How might these trends reshape your region’s plans? Share your thoughts in the comments.
