OpenSummit is our summer service that provides precipitation, lightning, temperature, and wind forecasts for mountain locations across the United States.
Since we first launched the service in the fall of 2016, we've continued to grow our audience on the iOS app, expanded the hourly forecasts to over 1,000 locations, and combined all OpenSnow & OpenSummit accounts, including the All-Access subscription.
