Idaho snowpack
Live SNOTEL readings, fresh snowfall, snow-water content, and 5-day forecasts at every monitored peak in Idaho. Sourced from USDA NRCS and NOAA NOHRSC.
Idaho's snowpack is at 42% of normal for today's date — well below the 70% drought-stress threshold. The deepest station is Nohrsc Snowschool 1 with 114" on the ground. Nohrsc Smiley Mountain is the coldest right now at 45°F. The biggest expected snowfall over the next 5 days is at Vienna Mine: 5".
The Idaho snowpack is monitored by the USDA NRCS SNOTEL network — automated stations sitting on the mountain that report snow depth, snow water equivalent (SWE), and air temperature every hour. Snoflo joins those live readings to a 5-day NOAA forecast for each station so you can see what's on the ground and what's coming.
Use the SNOTEL inventory below to find the closest station to where you're headed. Percent of normal tells you how today's snowpack compares to the historical average for the same date — below 70% is drought-stressed; above 130% is a fat year. Snow water content (SWC) indicates how wet and dense the snowpack is — useful for water-supply planning and avalanche stability assessment.
For backcountry travel always cross-reference with your regional avalanche center at avalanche.org.

About Idaho snowpack
Where does the Idaho snowpack data come from?
The USDA NRCS SNOTEL network (SNOpack TELemetry) -- automated mountain stations that continuously measure snow depth, snow water equivalent, precipitation, and air temperature. Snoflo aggregates the live readings and joins them to a 5-day NOAA forecast for each station.
What is 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 -- useful for water-supply forecasting and avalanche assessment. The "SWC %" column shows the ratio.
What does Percent Normal mean?
Current snowpack as a percentage of the historical average for the same date at that station. 100% is right at the historical norm. Below 70% indicates drought-stressed snowpack; above 130% is a fat year.
How fresh is the Idaho data?
SNOTEL stations transmit hourly; Snoflo re-pulls throughout the day. The 5-day forecasts regenerate from NOAA NOHRSC analysis fields and NWS forecast guidance.
Why are SNOTEL stations only in some states?
The NRCS SNOTEL network is concentrated in the western mountain U.S. -- where the snowpack drives federal water supply forecasts for irrigation, hydropower, and municipal water. Eastern snowpack is measured by other networks (CoCoRaHS, NWS) which Snoflo includes elsewhere.
Is this a substitute for the local avalanche center?
No. For backcountry travel always consult your regional avalanche forecast at avalanche.org. Snoflo is informational data only.
