This map displays current snow depth according to the National Oceanic and Atmospheric Administration
(NOAA) National Snow Analyses (NSA). The NSA are based on modeled snow pack characteristics that are
updated each day using all operationally available ground, airborne, and satellite observations of snow
water equivalent, snow depth, and snow cover. The NSA are products of the National Operational Hydrologic
Remote Sensing Center (NOHRSC).
