State Readings

Currently the state’s SNOTELs are reading 104 percent of median with a basin high of 118 percent and a basin low of 88 percent. Last year the state was at 115 percent, and at 148 percent in 2017. The map may differ slightly from the table depending upon how many stations were reporting at the time. This report and a map displaying basin SWE percentages of median for the state may be found at: wrds.uwyo.edu/wrds/nrcs/nrcs.html.

SNOW WATER EQUIVALENT AS PERCENT OF MEDIAN. The following table shows the percent of median for Feb. 25, the two previous weeks, one year ago and two years ago for Wyoming basins. Normal (median) is based on all reporting SNOTEL sites in the basin with calculated medians (newer SNOTEL sites do not have medians figured), but does not include manually measured snow courses. The statewide SNOTEL percent of median is a percent of median using all SNOTEL sites in Wyoming with calculated medians. The weighted state average is figured using the area of basins (square miles). The reference period for computing medians is the 30-year period 1981 through 2010.
