Regional snowpack

Nearby SNOTEL stations

USDA NRCS SNOTEL stations within driving range. Cross-check whether the snow at Arapahoe Basin is a one-off accumulation or a regional storm cycle.

Mountain & avalanche safety

Know before you go
Check today's avalanche bulletin from the regional avalanche center before any off-piste / side-country / backcountry travel. Conditions can shift dramatically between morning and afternoon on storm days.
Carry the gear, know how to use it
Beacon, shovel, probe. Practice companion rescue on a calm day, not during a real burial.
Mind the weather window
Heavy snow + wind builds wind slabs at ridgelines. The day after a storm is often the riskiest in the backcountry, even if the resort itself is open.
Respect closed terrain
Ropes are there for a reason. Even in-bounds, ducking a closure can trigger a slide that catches you and others below.

Save this resort as a favorite, set push alerts when snowfall crosses a threshold (e.g. "alert me when Arapahoe Basin reports 6″ new"), and Snoflo's iOS app will push the moment the SNOTEL station crosses.

FAQ

About Arapahoe Basin

Where does the snow data for Arapahoe Basin come from?

Snowpack, SWE, 24-hour snowfall, and air temperature come from the nearest USDA NRCS SNOTEL station. Forecast comes from the National Weather Service / yr.no feed that Snoflo's iOS app uses.

How often is the snow report updated?

Snowpack and SNOTEL data are updated continuously by NRCS (typically hourly). The 15-day weather forecast is refreshed throughout the day. Snoflo caches and renders the most recent observation -- look for the "as of" timestamp on the snowpack hero.

What's the elevation at Arapahoe Basin?

See the Resort Metrics panel above for base / summit / vertical drop. The summit elevation drives snowpack accumulation -- higher summits hold snow longer through spring.

How is "% of normal" calculated?

Today's snowpack is compared to the average snowpack on this calendar day across every recorded year at the nearest SNOTEL. 100% means right on average; 130% is a big year; 60% is thin.
