One of the most underutilized features of OpenSnow is the ability to track ongoing and incoming precipitation with our high-resolution "Current US Radar" and "Forecast US Radar" map overlays.

  1. Tap the "Maps" tab.
  2. Tap the overlay button.
  3. Tap "Current US Radar" or "Forecast US Radar".
  4. Scrub the bottom slider.
The "Current US Radar" is updated every 8 minutes to help you track ongoing precipitation for the past 2 hours, while the "Forecast US Radar" is updated every hour to help you track forecasted precipitation for the next 2 days.

Please note that these map layers are currently only available in the United States and southern Canada but we are working to provide global radar coverage very soon.

Two more tidbits...

First, radar has more difficulty detecting snow compared to rain. During winter, this means that intense snow might be falling even if the radar map shows low dBZ values (blue and green).

Second, big mountains block the radar beam from detecting precipitation close to the mountain tops. During the summer, this usually is a less important issue because thunderstorms rise far above the mountain tops and the radar can detect them. During the winter, radar might show little or no snow over the mountains even if a snowstorm is raging. We recommend also checking live webcams.

Track incoming storms on any device by upgrading to All-Access. The benefits also include webcam widgets for your iPhone home screen, forecasts anywhere on Earth, local "Daily Snow" analysis, custom snow alerts, and much more.
