Monday morning...

The National Weather Service in Riverton has issued a Winter
Storm Watch... which is in effect from Saturday evening through
Monday morning.

* Summary and timing... snowfall will move into western Wyoming
Saturday evening... and may become heavy on Sunday across the
area before weakening on Monday morning.

* Snow accumulations... the valley locations may see 5 to 10 inches
of snowfall with this system with the higher accumulations
expected across the northern portion of the Jackson Valley.
Mountain locations could see 12 to 16 inches... with locally
higher amounts to 24 inches.

* Wind and visibility... wind will be strongest over the higher
elevations... and may impact mountain passes with west wind of 25
to 35 mph with gusts over 50 mph. Even the lower elevations will
see southwest wind increasing to 15 to 25 mph on Sunday with
gusts to 35 mph in open areas. The wind and snowfall will limit
the visibility to under one half mile at times.

* Impacts... the combination of snowfall and wind over the higher
elevations would have an adverse impact on travelers across the
area. Significant snowfall across the valleys will create
hazardous driving conditions due to snow packed roadways.

Precautionary/preparedness actions...

Remember... a Winter Storm Watch means conditions are favorable
for hazardous winter weather in and close to the watch area.
