Live snowpack across the country.
Real-time SNOTEL depths, fresh snowfall over the past 24 hours, and 5-day forecasts at every monitored peak. Daily AI briefing summarises the picture in one paragraph — refreshed throughout the day from USDA NRCS and NOAA NOHRSC feeds.
What the snow's doing right now
An AI-generated summary stitched from today's SNOTEL readings, NOHRSC analysis fields, and NWS snow alerts.
While the Lower 48 states experienced minimal snow accumulation over the past 24 hours, Alaska's Brooks Range is positioning itself as the nation's winter weather hotspot, with forecasters calling for substantial snowfall over the next two days. The most impressive totals are expected at Imnaviat Creek, where six inches of fresh snow combined with rain, fog, and blustery conditions will create challenging travel scenarios across Alaska's North Slope. Meanwhile, recent observations from Washington's Cascade Range and Colorado's San Juan Mountains recorded modest two-inch accumulations, though these totals pale in comparison to what's developing in the Far North.
The evolving Alaskan storm system deserves particular attention from snow enthusiasts, as Atigun Pass—a critical corridor along the Dalton Highway—is forecast to receive four inches of new snow amid freezing fog and mixed precipitation. This mountain pass, sitting at the Continental Divide in the Brooks Range, frequently experiences some of the nation's most extreme winter conditions, and this event appears poised to deliver classic Arctic weather. Even Prudhoe Bay, typically known more for bitter cold than heavy snowfall, could see two inches as the system sweeps across the tundra. The combination of snow, rain, and dense fog will create particularly treacherous conditions for the oil field workers and truckers who navigate this remote region daily.
In the Lower 48, the snow story remains relatively quiet, though not without interest. Washington's Sawmill Ridge in the Cascades added two inches to its already impressive 170-inch base, demonstrating the region's remarkable snowpack despite late-season timing. Colorado's Vallecito area also recorded two inches, though its meager three-inch base suggests this is likely an early-season or high-elevation event rather than sustained winter conditions. Both locations face thunderstorm activity in their forecasts, indicating transitional weather patterns rather than sustained winter systems. For powder enthusiasts seeking the deepest, most intense snowfall over the next 48 hours, all eyes should turn northward to Alaska's Brooks Range, where the combination of accumulation, wind, and Arctic conditions promises the kind of raw winter experience that defines the season's most memorable events.
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.
