Two More Notes
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.
