...Creeks and rivers along the Upper North Platte, Little Snake, and
Laramie River Basins are expected to run at high levels Saturday night
through Monday...

Snowmelt runoff will drastically increase Friday and Saturday afternoon as
temperatures at the 9000 foot elevation are expected to be in the upper 50s to
near 60. Windy conditions in the mountains Friday and Saturday night will keep
temperatures above the frost temperature of 37 degrees which will continue
snowmelt runoff through the late night and early morning hours.

A chance of showers are forecasted over the mountains for Friday and
Saturday afternoon. Snow levels will start out at 10000 feet on Friday...
lowering to 9500 feet by Sunday night.

Smaller creeks and streams along the Upper North Platte, Little
Snake, and Laramie River Basins will run at high levels beginning Saturday
night and may begin to flood by early Sunday morning. Flooding of small
creeks and streams is possible through Monday.

The North Platte River at Saratoga is expected to rise to minor flood stage
by late Sunday morning.  The Little Snake River near Dixon is expected to rise
above minor flood stage by Sunday morning. The Encampment River at Riverside

near creeks and streams should be ready to move to higher ground when water
levels begin to rise.
