Snowline

What this is

I built this for myself. I ski the Pacific Northwest and I got tired of opening four tabs — a snow report, a forecast, an avalanche bulletin, a road map — none of which reference each other, to answer one question: is tomorrow worth the drive.

You're welcome to use it. But please treat it as one person's convenience tool, not a public service. It is not staffed, not monitored, and has no obligation to anyone. Before you drive or ski on anything you read here, confirm it against the sources that are maintained as public services — your state DOT, your regional avalanche center, the mountain itself. Those are linked on every card and listed below. If this page and one of them disagree, they're right.

How it works

Every number comes from a public feed, joined together when you load the page. The point isn't new data — it's that nobody was putting it in one place.

Snow & weather

Open-Meteo — snowfall for the three days past and seven ahead, at the mountain's own elevation. Past snowfall matters more than forecast snowfall and most tools show only the forecast.

Avalanche danger

avalanche.org / the National Avalanche Center, via the forecast-zone polygons each regional center publishes. Each mountain is matched to its zone geometrically.

Roads & passes

WSDOT Traveler Information for Washington passes and ODOT TripCheck for Oregon.

This is not a safety tool, and it is not a public service. The avalanche rating shown is the published backcountry danger for the surrounding forecast zone — it says nothing about conditions inside a ski area boundary, and it is a summary of a document you should read in full. Before travelling in avalanche terrain, read that forecast from your regional center. Before driving, check your DOT. The verdict on each card is an opinion assembled from the numbers beside it, and it is often wrong. Feeds go stale and break, and nobody is watching this page to notice.
