On April 1, when federal hydrologists took their most important snowpack measurement of the year, the numbers that came back from 1,575 monitoring stations across the West were the worst in roughly four decades. Snowfields that normally hold billions of gallons of slow-release water for rivers, reservoirs, and soil moisture had already melted or never fully formed. Within weeks, AccuWeather responded by raising its 2026 wildfire acreage forecast past 5.5 million acres, a figure that, if realized, would exceed last year’s already above-average burn and rank among the most destructive fire seasons on record.
The West has entered summer with a moisture deficit it cannot recover from. What happens next depends on monsoon rains, lightning, wind, and human decisions. But the starting conditions are now locked in, and they are severe.
The snowpack collapse, by the numbers
The USDA’s Natural Resources Conservation Service, which operates the SNOTEL automated sensor network, reported that April 1 snow water equivalent readings fell to record or near-record lows at stations spanning the Cascades, the Sierra Nevada, the Rockies, and the ranges of the Interior West. Some of those measurement records stretch back more than 70 years, meaning the 2026 readings are historically unusual even compared to the severe droughts of the 1970s and early 2000s.
State-level data sharpens the picture:
- California: The Department of Water Resources reported that the state’s April 1 snowpack ranked as the second-lowest on record. A record-hot, dry March wiped out measurable snow statewide, and automated sensors showed the snowpack peaked around February 24, more than a month earlier than the typical late-March or early-April window.
- Washington: NRCS officials measured April 1 snow water equivalent at roughly 52 percent of normal, with multiple stations posting record or near-record lows across both coastal and interior basins.
- Idaho: Governor Brad Little issued a statewide drought emergency declaration tied directly to the snow drought, triggering water-use restrictions and emergency planning.
- Wyoming: State officials activated priority water administration measures designed to stretch limited supplies through the irrigation season.
NASA satellite imagery confirmed the ground-level readings, showing scarce snow cover across the Upper Colorado River Basin, a system that supplies water to roughly 40 million people in seven states. The convergence of automated sensors, manual snow courses, satellite observations, and emergency policy responses all point in the same direction: the West’s mountain water bank is nearly empty heading into its hottest months.
Why low snowpack fuels worse fire seasons
Mountain snowpack acts as a slow-release moisture system. As it melts through May and June, it feeds streams, raises water tables, and keeps soils and vegetation damp during the transition from spring to summer. When that reservoir is depleted early, the drying timeline accelerates. Forests, grasslands, and shrublands that would normally retain moisture into July can reach critical fire-readiness weeks ahead of schedule.
The problem compounds in areas that experienced wet winters in recent prior years. Seasons of above-average rain and snow allowed grasses and brush to grow thick across parts of the Great Basin, the eastern Sierra foothills, and the Colorado Plateau. That vegetation is now curing under hot, dry conditions, creating continuous fuel beds that can carry fire rapidly across open landscapes. It is the classic one-two punch of western fire: a wet year grows the fuel, and a dry year ignites it.
For context, the National Interagency Fire Center recorded 77,850 wildfires that burned 5,131,474 acres in 2025, a total that already exceeded the 10-year average. AccuWeather’s projection of more than 5.5 million acres for 2026 implies a season that could surpass last year by a significant margin.
What could change the trajectory
The 5.5-million-acre figure is a commercial forecast, not a federal projection. AccuWeather has not publicly detailed the methodology, station-level inputs, or confidence intervals behind the number. Private weather firms typically blend government snowpack data, seasonal temperature outlooks, and proprietary models, but without a published methodology, independent verification of the specific acreage target is not possible. It should be treated as a planning signal, not a certainty.
Several factors could push the final tally significantly higher or lower:
The North American Monsoon. In years when monsoon moisture arrives on schedule between July and September, fire activity across Arizona, New Mexico, and parts of Colorado can drop sharply, even when spring snowpack is poor. Federal seasonal climate outlooks have not yet confirmed whether the 2026 monsoon will arrive at normal strength. A robust monsoon would not erase the risk created by depleted snowpack, but it could meaningfully reduce total acreage by shortening the window when fine fuels are driest.
Summer precipitation patterns. Intermittent rain events during June and July can temporarily green up fine fuels and slow fire spread, even in drought years. The timing and sequence of these events will matter as much as seasonal averages.
Lightning and wind. The largest single-fire events in the West are often driven by dry lightning storms that ignite multiple fires simultaneously, followed by wind events that push them beyond containment. These are inherently unpredictable weeks or months in advance.
Firefighting capacity. Federal wildland fire agencies have faced persistent staffing shortages and budget pressures in recent years. The number of available hotshot crews, air tankers, and engines at the moment of peak demand can determine whether a 500-acre fire stays at 500 acres or grows to 50,000. Pre-positioning decisions being made now will shape outcomes later this summer.
What communities should be doing now
The snowpack deficit is already baked in. No late-season storm will refill what the mountains lost. That makes the next several weeks a critical preparation window for communities in fire-prone areas.
Fire agencies and land managers are accelerating defensible-space inspections and fuel-reduction work around the wildland-urban interface. Utilities in California, Oregon, and Washington are reviewing Public Safety Power Shutoff protocols and vegetation management along transmission corridors. County emergency managers across the Interior West are updating evacuation routes and shelter plans.
For individual homeowners, the checklist is familiar but urgent: clear brush and dead vegetation within 100 feet of structures, clean gutters and roof surfaces of dry debris, confirm that go-bags and evacuation plans are current, and sign up for local emergency alert systems.
The outlook will sharpen as summer progresses. NIFC publishes updated national significant wildland fire potential outlooks monthly, and those reports will incorporate real-time fuel moisture readings, weather pattern shifts, and early-season fire activity. Tracking those updates offers a more reliable guide than any single preseason number.
What is already clear is that the West is starting from a position of unusual vulnerability. The mountains gave back their water early, the drought declarations are already signed, and the fuels are drying faster than normal. The fire season’s final toll is still unwritten, but the conditions that will shape it are not.
