Alta continues to see some light snow. This stuff is barely discernible in the radar loop where all one sees are some stronger returns over the high terrain that are ground clutter and some very light returns in a couple of bands that move from east to west across the Wasatch Range, consistent with precipitation in the "wrap around" part of the storm.
It's very difficult to determine precipitation rates at Alta and in other parts of the Wasatch Range during such conditions using radar. There are a couple of reasons for this. First, the precipitation is quite shallow and often the radar beam partially or totally overshoots the precipitation.
