About Snoflo

Climate intelligence for the great outdoors.

We pull the snow, water, weather, and wildfire data the country already publishes — and put it on one fast map for the people who actually use it. Built since 2015 for skiers, paddlers, anglers, ranchers, and water managers.

Snoflo started because checking the snowpack meant cross-referencing five government websites — one for SNOTEL stations, one for streamgauges, one for reservoirs, one for weather warnings, one for the FEMA flood layer. None of them talked to each other. None of them were designed for the dawn-patrol skier or the river guide trying to call a put-in.

We pulled the data into one map. Then we made it fast. Then we made it free. The posture has not changed since: take the data the country already publishes, present it the way humans actually need it, and don't get in the way.

Today Snoflo ingests live signals from 800+ NRCS SNOTEL stations, 10,000+ USGS streamgauges, NOAA / National Weather Service feeds, NOHRSC snow analysis fields, USBR reservoir telemetry, FEMA flood zones, NIFC wildfire perimeters, NASA satellite layers, and more. Daily AI briefings stitch the picture together. Push alerts ping you the moment a station crosses the threshold you set.

Snoflo is operated by Snoflo.org LLC, an independent company. We don't take venture capital and we don't sell user data. The free tier is supported by display ads; a Premium subscription removes them and unlocks professional features. That's the whole business model — plus the conviction that this stuff should exist whether or not it makes anyone rich.

What we won't do

Plain-language principles

The product looks the way it does because of these. We'd rather miss a quarter than ship a feature that breaks one.

Honest ads on free, none on Premium.

The free tier is supported by display ads — that's how we keep the data flowing without selling user data or charging at the door. Upgrade to Premium and the ads disappear entirely. No sponsored map pins, no "promoted" alerts, ever, on either tier.

No tracking, no selling data.

We don't use Google Analytics. We don't sell user data. We don't share with brokers. The privacy page lays out exactly what we do and don't collect.

Open underlying data.

Every layer on Snoflo comes from a publicly available federal feed. We attribute the agencies. If we put it on the map, you can verify it at the source.
