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.
