Create Custom Snow Report Alerts
The third and final step to getting the most out of your OpenSnow account will be creating custom snow report alerts.
Custom snow forecast alerts are also available to All-Access subscribers, which are sent when night + day forecast for a single day is greater than the threshold you set.
Choosing which mountain has the best snow can feel overwhelming. With OpenSnow, deciding where to go is easy. Compare the latest forecasts, conditions, and cams for your favorite mountains in just a few seconds.
The first tab under Favorites is 'Mountains'. This scrolls vertically, with horizontally scrolling chips that provide easy-to-compare Summary, 10-Day Forecast, 10-Day History, All Cams, Snow Report, and Temperature cards for each mountain.
The next tab is 'Daily Snows'. Simply scroll to find the latest update for your favorite mountains from our team of local forecasters.
The fourth tab is 'Passes'. The Top 5-Day Forecast and Top 24-Hour Report will always be updated to quickly give you an idea of where the snow is stacking up on your pass(es).
The fifth and final tab under Favorites is 'Trail Maps'. Simply favorite any trail map to easily access from your Favorites screen.
Offline trail maps are also available to All-Access subscribers in the OpenSnow app.
Ski Resort & Backcountry Locations
Upon initial load of any individual ski resort or backcountry location screen, we provide a quick snow forecast summary graph and value for expected snowfall over the next 5 days, followed by the next 6-10 days, under the 'Forecast' tab.
The next section is labeled as '5-Day Hourly Forecast or Coming Up'. Free users can see 6 hours of the hourly data, while All-Access subscribers can see the next 5 days.
In the OpenSnow app, click the 'Hourly Forecast For 5 Days' button to view the chance of precipitation (including precip type), temperature, snow level, wind speed, wind gust, and cloud cover.
Use this data to time the next storm and dress appropriately for changing conditions on the mountain.
Further down any location screen under the 'Forecast' tab, you will find the 1-10 day snow forecast under the section titled 'Detailed 10-Day Forecast or Next 10 Days'.
In the app, tapping the 'Full 10-Day Forecast' button provides access to the latest snow forecast for each day and night for the next 10 days, alerts (powder days, mixed precipitation, rain, high winds), temperature, snow level, wind speed, wind gust, and cloud cover %.
Looking for the latest 'Snow Report', 'Cams', 'Daily Snows', 'Trail Maps', 'Avalanche Forecast', and 'Mountain Info'? Simply tap each tab at the top of the screen and scroll through to find the latest updates.
Base Depth vs. Average graphs can also be found under the 'Snow Report' tab. This data is updated daily on OpenSnow and available to All-Access members for nearly every mountain location in the western US.
We make it easy (and beautiful) to see if there is snow heading toward your favorite mountains, along with how much snow fell over the past 24 hours, season-to-date, and snow depth. You can also view 2-day forecast animations for precipitation, wildfire smoke, wind gust, cloud cover, and temperature, as well as the latest avalanche forecast and conditions for the past 7 days.

Once you sign up for the Group plan, invite three friends or family members. They will have their own account and can set up their own list of favorite mountains, custom snow alerts, and more.
(Q) How do you calculate the snow forecast summary?
We calculate the snow forecast summary by taking the snow forecast for the previous night + the current day. The summary calculation is shown this way since this is the snow that you would see/ski on that day.
Example: The snow forecast summary has 12 inches for Friday.
- Thursday Night = 5-9 inches = 7 inches
- Friday Day = 3-7 inches = 5 inches
Friday Summary = 12 inches
(Q) How do you make your forecasts?
The forecasts on OpenSnow are updated every hour with a proprietary blend of global data from the GFS (American), GDPS (Canadian), and ICON (German) weather models, along with high-resolution data from the HRRR (American) and HRDPS (Canadian) weather models.
The benefits of this approach include:
- Proprietary algorithm to improve the snow-to-liquid ratio, precipitation, temperature, and wind speed calculations for cold, mountain environments.
- Provides the ability to create a forecast for any location (and elevation) to ensure that we are forecasting conditions on the mountain and not for a nearby town.
- An improved method for calculating the snow level (elevation that separates rain from snow) to provide a more realistic forecast, especially at the beginning of storms and during times of intense snowfall.
- Blending multiple global and high-resolution models increases accuracy and confidence in the forecast.
This blend of proprietary forecast data is updated every hour on OpenSnow for thousands of locations around the world and we are adding new locations every day.
(Q) What weather forecast data is available on OpenSnow?
The weather data on OpenSnow can be viewed as hourly forecasts for the next 5 days and daily forecasts for the next 10 days. Available forecast data includes:
- Day & Night Snow Forecast
- Day & Night Snow Level
- Daily High & Low Temperature
- Hourly Chance of Precipitation

- Hourly Wind Speed, Gust, & Direction
- Hourly Cloud Cover %

(Q) What do the different colored alerts signal?
Daily alerts are included to signal upcoming powder days, along with the potential for rain, snow/rain, and high winds. Alert breakdown:
- Blue = Powder (Forecast of 6+ inches from the previous night and current day)
- Green = Rain (Expect rain on all of the mountain)
- Purple = Snow/Rain (Expect a transition from snow to rain on the mountain)
- Yellow = Wind (Wind gusts greater than 45 MPH and possible lift closures)
(Q) What is the difference between the blue and orange snow forecast bars?
Blue bars show snowfall under 6 inches. Orange bars show snowfall over 6 inches. The color change is simply a visual clue to denote the higher snow totals and deeper powder.
(Q) How do you break up the day and night 10-day forecast?
The "day" forecast is from 6 AM to 6 PM, while the "night" forecast is from 6 PM to 6 AM.
