    Winter storm brings much-needed snowpack

    As of March 15th, Wyoming’s snowpack/snow water equivalents (SWEs) has increased to 98% of the median, according to a report from Wyoming NRCS Hydrologist Jim Fahey. Last year, the state median average was at 113%.

    This winter storm that shut down most of Wyoming over the weekend and into today increased the statewide SWE by 9%.

    The basins with the largest increases in snowpack/SWE from the previous week include the South Platte (+43%), the Lower North Platte (+42%), the Laramie (+25%), and the Powder (+20%). Check out the map below.

    The following table shows the percent of median for March 15th, the 2 previous weeks, one year ago, and two years ago for Wyoming basins.

    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 the median for the state may be found here.

    Accumulating mountain snow is expected during the upcoming week across basins east of the continental divide (see 7-day precipitation totals map in report).
