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.
- Tap the "Maps"
tab.
- Tap the overlay button.
- Tap "Current US
Radar" or "Forecast US
Radar".
- 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.
