Highlights

  • February precipitation was mainly below-average for the region, with the driest conditions across Utah; eastern Colorado and central Wyoming saw above-average precipitation.
  • Snowpacks are now below-average in nearly every basin across the region after a dry February caused the snowpacks in Utah and western Wyoming to lose ground compared to average conditions
  • The March 1 spring-summer streamflow forecasts for the region call for well-below-average (<70%) runoff in nearly all basins, reflecting both the low snowpacks and the unusually low soil moisture last fall
  • The NOAA CPC seasonal climate outlooks show a dry “tilt” for spring and early summer precipitation for most of our region, though the one-month outlook for March has no tilt. In contrast, the “SWcast” for April–June shows a wet tilt over Colorado and eastern Utah.
