Initial Jan. 2013 State Spring Snowmelt Flood Potential Outlook - issued Jan. 23

Quick Synopsis:

 

Mountain snowpack and associated snow water equivalents (SWEs) across Wyoming were generally below average by the middle of January.  SWEs at the peak snowmelt runoff elevations (8,000’ – 9.500’) were the highest across northwestern Wyoming at 100 – 115 percent of normal; while across southeastern Wyoming, SWEs were 50 to 75 percent of average at the peak snowmelt runoff elevations.

 

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 February.
