Headwater locations of the Tongue and Powder Watersheds had above normal snow water equivalents (SWEs) at the beginning of January. A few headwater locations along the Upper North Platte Drainage also had above normal SWEs in the beginning of January. All other headwater basins in Wyoming had near normal to just below normal SWEs by the beginning of the month.
The initial spring 2008 snowmelt flood potential outlook calls for a low to moderate potential for headwater snowmelt flooding across the Tongue, Powder and Upper North Platte Basins. All other headwater locations across Wyoming can expect a generally low potential for flooding due to springtime snowmelt.
