How it works

01
The Snow Depth layer over the Coast Mountains, from Juneau to Prince Rupert

Turn on snow depth

The Snow Depth layer colours the whole range by how much snow is on the ground today. It is rebuilt daily from the same models forecasters use.

02
The Conditions sheet for a tapped point, with the next 48 hours and the 16-day forecast, over the Snow Depth layer

Tap any point

Get a point forecast for exactly where you tapped: current conditions, hourly and daily, with charts. Sun, moon and air quality sit in the same sheet.

03
A weather alert on the map, with its detail open

Watch the alerts

Weather alerts from NWS and ECCC show for your area. The app also nudges you when you are about to leave cell coverage.

Sources / What it does not do

Sources
  • Snow depth: NOAA SNODAS in the United States, ECCC HRDPS in Canada, GFS elsewhere. Rebuilt daily.
  • Point forecast: Open-Meteo, served through Aventerra's own server.
  • Weather alerts: NWS in the United States, ECCC in Canada.
Data sources
What it does not do
  • Snow depth is a daily model analysis, not a reading from a station at your location.
  • Conditions are decision support. They do not replace your own observations on the ground.
  • Weather alerts are issued by NWS and ECCC, so they cover the United States and Canada.
  • Snow depth covers the world. It is sharpest in the United States (SNODAS) and in Canada and Alaska (HRDPS); elsewhere it comes from the coarser GFS model.

Frequently asked

Where does the snow data come from?

NOAA SNODAS (Snow Data Assimilation System) and Environment Canada HRDPS (High Resolution Deterministic Prediction System), the same government weather and snow models that Canadian and US forecasters rely on. Updated daily. HRDPS data is provided under the Open Government Licence - Canada.

How often is snow depth updated?

Once a day. The layer is rebuilt from the latest SNODAS, HRDPS and GFS analyses, so what you see is the model's picture for today.

Can I check conditions on my watch?

Yes. The companion watch app shows conditions for where you are, alongside recording controls, SOS and back-to-start.
