Spring Snowmelt Forecast

Spring Snowmelt Forecast

The most recent Spring Snowmelt Forecast was issued on Feb 20, 2012  Given normal precipitation the remainder of the snow season, Star Valley  area, including  the Salt and Grey Rivers will experience below normal runoff, but still better than much of the remainder of Wyoming.

February 2013 Wyoming Spring Snowmelt Flood Potential Outlook—issued February 20th

Quick Synopsis:
Mountain snowpack and associated snow water equivalents (SWEs) across Wyoming continued to be generally below average by the middle of February.  SWEs at the peak snowmelt runoff elevations (8,000’ – 9.500’) were the highest across northern Wyoming at 95 – 105 percent of normal; while across southeastern Wyoming, SWEs were 65 to 75 percent of average at the peak snowmelt runoff elevations.
This outlook is based on various diverse hydrological factors such as snow water equivalents (SWEs) in the mountain snowpack, basin morphology, extent of burn scars from 2012 fires, amount of bark beetle kill, and
HIGHLIGHTS:
 …The majority of headwater basins across Wyoming can expect a generally low potential for flooding due to springtime snowmelt…
The next graphical outlook will be issued around the 23rd of March.
