Hydrologic Outlook
National Weather Service Riverton WY
720 PM MDT Sun May 31 2020

...Higher Water Levels to continue this Week...

Snow in the far western Wyoming mountains between the 8,000 and
10,000 foot elevation will continue to melt during the coming
week. Monday will remain quite warm before temperatures cool
slightly through the week. However, even these cooler readings
will be above normal for early June. East of the Continental
Divide, the remaining snow is mainly confined to elevations above
9,000 feet. Much above normal temperatures will continue Monday
east of the Divide and an active snowmelt will continue all week.

Conditions will be mostly dry Monday with only isolated showers
and thunderstorms expected. The far northern mountains have a
better chance of rain showers Tuesday afternoon and evening. The
showers and thunderstorms will become more widespread from
Thursday afternoon into next weekend.

The greatest concern for minor flooding remains across western
Wyoming where the best snowpack persists. The river stages at both
Pacific Creek near Moran and the Gros Ventre River at Kelly will
generally remain bankfull. The Green River at La Barge is forecast
to climb to near action stage of 8.0 feet by Wednesday.

Other areas of concern include the upper Wind River from Dubois to
Kinnear. The river will be around flood stage around Dubois while
near bankfull downstream through Kinnear through midweek. Creeks
and streams along the west slope of the Bighorn Range, including
Tensleep Creek, Medicine Lodge Creek, and Paintrock Creek may run
bankfull at times through Monday. Rainfall Saturday evening caused
water levels to rise on these foothill creeks.

Remember, during active snowmelt runoff, mountain and foothill
creeks flow highest from late evening through early morning.
Recreationists should stay away from these cold, fast-moving
streams and avoid camping near any waterway. Do not attempt to
cross a creek or stream on foot as the power of the water will
easily carry you downstream.

Hydrologic Outlook
National Weather Service Billings MT
951 AM MDT Sun May 31 2020

...Rising river and stream levels will continue into early this
week...

Hot temperatures are expected today. Although temperatures will be
cooler to begin the week, readings will remain above normal. This
will result in continued melting of the existing snow pack (above
8000 feet) in the mountains into early this week. The snow melt will
cause increased flows along rivers and streams emerging from the
mountains. This includes the Yellowstone, Clarks Fork of the
Yellowstone, Shields, Boulder, Stillwater, Little Bighorn and Tongue
Rivers, as well as numerous other smaller streams.

Afternoon temperatures at 8000 feet will reach the 60s and 70s, and
overnight temperatures will stay above freezing through much of the
night. Flooding resulting in significant impacts is not expected at
this time. However, some minor flooding is possible especially on
the Clarks Fork of the Yellowstone near Belfry. Many rivers will
reach the highest levels we have seen this spring.

Recreationists near the foothills should be prepared for changing
conditions and use extra caution when in and near the water. Flows
will be fast, and the water is cold. Those with interests near
waterways should move equipment and livestock away from low lying
areas.
