Spatial Estimates of Snow-Water Equivalent (SWE) Intermountain West Region March 12, 2020 — Western Water Assessment

Summary of current conditions (as of 3/12/20)
On March 12th the modeled snow conditions are mostly below the 2001-12 average across the Intermountain West domain, with most basins at 75-95% and a couple above 100% of average . Snow conditions remain low (<80% of average) in the central basins: North Platte, White-Yampa, CO Headwaters, Dolores, San Juan and Upper Arkansas. The eastern and western basins are between 80-95%, with the Big Horn and South Platte above average. At lower elevations, our model estimates indicate generally below average SWE for this time of year, while SWE predictions at higher elevations are above average – consistent with SNOTEL observations. The basin-wide percent of average from the spatial SWE estimates is not directly comparable with the SNOTEL basin-wide percent of average. A better comparison might be made with the % average in the elevation bands that contain SNOTEL sites.
