Avalanche
Avalanches are a serious hazard across the western U.S. and the Northeast — the U.S. averages 25-30 fatalities per year, almost all in the backcountry. Most accidents involve recreational users who triggered the slide themselves: backcountry skiers and snowboarders, snowmobilers, climbers.
Snoflo's avalanche page combines two things: live regional danger ratings from avalanche.org's API (red = high danger today) and a historical event database from the Colorado Avalanche Information Center showing accidents by year, state, cause, and fatalities going back decades.
For trip planning: always read the current bulletin from your regional avalanche center, not just the rating. Check terrain, weather, and snowpack conditions. Carry a beacon, probe, and shovel and know how to use them. Never travel alone in avalanche terrain.

Avalanche FAQ
About the avalanche data
Where do the live danger ratings come from?
Live regional danger ratings come from avalanche.org's public API, which aggregates today's bulletins from every U.S. avalanche center (CAIC, NWAC, UAC, GNFAC, BTAC, FAC, BAC, MWAC, and more). Snoflo overlays these on the map.
Where does the historical event database come from?
The historical accident database is maintained by the Colorado Avalanche Information Center (CAIC). CAIC tracks accidents involving people across the U.S. going back decades and is the canonical reference for avalanche statistics.
What are the danger ratings?
The North American Public Avalanche Danger Scale uses five levels: Low (1) · Moderate (2) · Considerable (3) · High (4) · Extreme (5). Even at "Low," human-triggered avalanches are possible — ratings describe likelihood and consequence, not absolute safety.
How fresh is the data?
Live danger ratings refresh whenever the regional avalanche center issues a new bulletin (typically once daily during the season, more often during high-danger events). The historical accident database updates as CAIC publishes new reports.
Is this a substitute for the local avalanche bulletin?
No. Always read the full bulletin from your regional avalanche center before backcountry travel — the rating tells you what level of danger exists, but the bulletin tells you where, why, and what kind of avalanche problem to expect. Snoflo is a discovery + planning tool, not a substitute for proper avalanche education.
What avalanche education should I get?
The American Institute for Avalanche Research and Education (AIARE) publishes the U.S. recreational avalanche curriculum. Take a Level 1 course before traveling solo in avalanche terrain. Carry beacon / probe / shovel and know how to use them under pressure.
