Why is the Avalanche Danger overlay empty?
If the Avalanche Danger overlay is empty, it's because there's no forecast published for that area right now.Nothing is broken, and there's nothing you need to fix.
The overlay only shows danger ratings that local avalanche forecast authorities have published. Slopes doesn't create its own ratings, so when a forecaster hasn't published one, there's nothing for us to show.
Why might there be no forecast?
- It's outside the forecast season. Most avalanche centers only publish forecasts during the winter. Before the season starts, or once it ends, the overlay will be empty.
- There's no forecaster covering that area. Not every area has a local avalanche forecast authority.
- The forecast has expired. Each forecast covers a set period. If the avalanche center hasn't published a new one yet, the overlay is greyed out, and your routes show the forecast as expired (for example, "Expired 2d ago").
- The forecast couldn't load. If you don't have signal, the forecast can't update. Try again once you're connected.
As soon as a forecast is published for that area, you'll see it on the map.
⚠️ An empty overlay does not mean there's no avalanche danger. It only means there's no published forecast for us to show. Always check with your local avalanche center before heading out.
Where do the ratings come from?
The danger ratings come from local avalanche forecast authorities, not from Slopes. We show you what they've published, but we don't make our own assessment of the avalanche danger.
The Avalanche Danger overlay is free for everyone. To turn it on, tap the layers button on the map, then Overlays → Avalanche Danger.
