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 daily using all operationally available ground, airborne, and satellite observations. The NSA are products of the National Operational Hydrologic Remote Sensing Center (NOHRSC).
Snow depth data is modeled at one square kilometer resolution. Due to inherent spatial and modeling uncertainties, this map should be used as a general planning tool, not as a source of snow depth measurements at precise locations. This map is not suitable for navigation. Contact the closest forest office for more information.
