What the snow's doing right now

Snow enthusiasts looking for meaningful accumulation should turn their attention northward this week, as Alaska's North Slope prepares for the most significant snowfall event in the nation. While the Lower 48 has recorded only modest snowfall over the past 24 hours—with Sawmill Ridge in Washington's Cascades and Vallecito in Colorado's San Juan Mountains each reporting 2 inches—the real story is unfolding across Alaska's remote northern reaches. Imnaviat Creek is forecast to receive an impressive 6 inches over the next 48 hours, with nearby Atigun Pass expecting 4 inches, making this the most substantial snow event currently developing across North America.
The contrast between current conditions and the forecast couldn't be starker. Washington's Sawmill Ridge, sitting at a healthy 170-inch base depth near the Mount Rainier corridor, received its 2 inches amid hazy conditions with thunderstorms threatening the region—an unusual late-season weather pattern that combines lingering snowpack with convective activity. Meanwhile, Colorado's Vallecito station, operating with a minimal 3-inch base in the southwestern part of the state, also logged 2 inches as showers transitioned to thunderstorms. These scattered accumulations in the Rockies and Cascades represent typical spring shoulder-season activity rather than any meaningful powder event for ski resort operations.
The developing Alaskan system presents far more compelling conditions for snow researchers and Arctic weather enthusiasts. Imnaviat Creek, located along the Dalton Highway corridor at 68.6°N latitude, will bear the brunt of this moisture-laden system, with 6 inches expected amid rain-snow mix and areas of fog. Atigun Pass, the highest point on the Dalton Highway at 4,739 feet elevation, should see 4 inches despite challenging conditions including freezing fog. Even Prudhoe Bay on the Arctic Ocean coast may pick up 2 inches, though precipitation could transition to rain in this industrial hub. This northern Alaska event represents a significant late-season or early-season snow burst—depending on your perspective in the Arctic—with blowing snow and reduced visibility likely creating treacherous conditions along North America's most remote highway corridor.

About the snow data
What's a SNOTEL station?
SNOpack TELemetry — automated stations operated by the USDA Natural Resources Conservation Service (NRCS). Each one continuously measures snow depth, snow water equivalent (SWE), precipitation, and air temperature. There are 800+ across the western U.S. and Alaska. They're the gold-standard snowpack measurement.
How fresh is the data?
SNOTEL stations transmit hourly. We re-pull every hour and re-rank the leaders. The AI briefing regenerates daily.
What's snow water equivalent (SWE)?
The depth of water you'd get if you melted the entire snowpack. A 30-inch snowpack with 8 inches of SWE is wetter and denser than one with 5 inches of SWE — useful for water-supply forecasting and avalanche assessment.
Where do the 5-day forecasts come from?
NOAA's National Operational Hydrologic Remote Sensing Center (NOHRSC) snow analysis fields plus standard NWS forecast guidance. We aggregate by SNOTEL location and rank by total expected accumulation.
Can I get an alert when fresh snow falls?
Yes. Save any SNOTEL station as a favorite in the Snoflo iOS app, set a fresh-snow threshold (e.g. "alert me on 6+ inches new snow"), and you'll get a push the moment it crosses. Free with a Snoflo account.
Is this a substitute for the local avalanche center?
No. For backcountry travel always consult your regional avalanche forecast (avalanche.org). Snoflo is informational data only.
