Snow depth · current metadata check
Last successful metadata check 2026-10-17 19:38:03.274 UTC; latest attempt 2026-10-17 19:38:02.808 UTC.
NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.
Scroll the map sideways on smaller screens. State borders, coastlines and city labels provide geographic context. Reference geography: U.S. Census Bureau / Natural Earth. Snow colors and the legend are NOAA’s original.

Raster selection, georeferencing and provenance
Raster catalog ID 1847708, zz_ssmv11036tS__T0001_latest.grib2. The export selects this ID and the footprint was unchanged before and after export. This check does not independently establish the pixels’ valid time.

Target: 24 hours of captured source versions, at most 16 per field. History begins with the first recorded capture; missing intervals are not interpolated. Source metadata clocks may repeat or differ from pixel analysis time.
