...Creeks and streams along the Big Wind and Little Wind 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
lower 60s. Windy conditions in the mountains Friday and Saturday nights will keep
temperatures above the frost temperature of 37 degrees which will continue
snowmelt runoff through the late night and early morning hours. Temperatures at
the 9000 foot elevation are expected to cool down to the upper 40s to lower
50s by Sunday afternoon.

A slight chance of showers are forecasted over the east slopes of the
Wind River Mountains Friday and Saturday afternoons.

Creeks and streams along the Big and Little Wind River Basins will run at high
levels beginning Saturday night and may begin to flood over low lying areas
and at stream and creek confluences by early Sunday morning. Flooding of low
lying areas and near creek and stream confluences is possible through early Monday.

The Little Wind River near Riverton is expected to rise steadily Saturday
through Monday and may reach flood stage by Monday afternoon. The Big Wind River
will see significant rises through the weekend but is expected to remain below
flood stage.

Avoid crossing small creeks and streams in the late afternoon through early
evening hours as the water levels are the highest during that time. People living
near creeks and streams should be ready to move to higher ground when water
levels begin to rise.
