Headwater locations along the Laramie, Powder, Tongue, Upper North Platte, and Little Snake Watersheds had near normal snow water equivalents (SWEs) at the beginning of February. A few headwater locations along the southern Wind River Drainage also had near normal SWEs during early February. All other headwater basins in Wyoming had below normal SWEs at the beginning of the month.
Expect a moderate potential for headwater snowmelt flooding across portions of the Laramie, Upper North Platte, and Little Snake Watersheds. Light to moderate spring snowmelt flood potential is expected across portions of the Powder, Tongue and southern Wind River Basins. All other headwater locations across Wyoming can expect a generally low potential for flooding due to springtime snowmelt.
