SYNOPSIS:

February 2019 precipitation totals across Wyoming were 115 to 125 percent of average. Precipitation numbers varied between 250 percent of normal over the Snake and Upper Yellowstone River Drainages (west to northwest Wyoming) to near 50 percent of average over the Tongue River Basin (north central Wyoming).  Current water year (October 2018 – February 2019) precipitation across Wyoming was 100 to 110 percent of average.

Mountain snowpack across Wyoming was 105 to 115 percent of median by early March.  Snowpack “water” numbers and/or SWEs were the highest across basins in southeast and western Wyoming—varying between 110 to 130 percent of median.  SWEs across basins in north central Wyoming were 80 to 100 percent of median.

Near normal to slightly above normal (95 to 105 percent) snowmelt streamflow volumes are expected across several major basins across Wyoming.  Above average snowmelt streamflow volumes are expected across the Snake, Shoshone, Upper North Platte and Laramie Watersheds.  Several rivers along the Tongue, Powder, and Upper Green Basins are forecasted to have below normal streamflow volumes during the upcoming snowmelt season.

Total reservoir capacity across Wyoming continues to be 70 to 75 percent by early March.  Reservoir storages across Wyoming remain above average at 105 to 115 percent for March.
