Avalanche Warning
Idaho Panhandle Avalanche Center Sandpoint ID
Relayed by National Weather Service Spokane WA
642 AM PDT Mon Mar 24 2025
The Idaho Panhandle Avalanche Center in Sandpoint has issued a
BACKCOUNTRY AVALANCHE WARNING for the following areas:
Bonner Count, Boundary County, Idaho.
* WHAT...An Avalanche Warning is in effect from Monday 6 AM to
Tuesday 6 AM. Very dangerous avalanche conditions have
developed from several feet of recent snowfall followed by
moderate to heavy rain saturating the snowpack and will last
through Tuesday morning. You can very easily trigger avalanches
large enough to bury, injure, or kill you, and some will release
spontaneously. Avoid travel in avalanche terrain during this
period.
* WHERE...The Selkirk Mountains, and West and East Cabinet
Mountains above 4,000 feet.
* WHEN...In effect from Mon 06:00 PDT to Tue 06:00 PDT.
* IMPACTS...Heavy snowfall formed dangerous slabs of snow three to
four feet deep. Now, an extended period of moderate to heavy
rainfall is saturating the dry snowpack and will quickly
overload numerous weak snow interfaces below. The snow line will
continue to rise to around 7,000 feet and stay at that
elevation through midweek. It will be very likely for
backcountry travelers to trigger large to very large avalanches
and natural avalanches are likely. Avalanches can break wide
across terrain features and run long distances to lower
elevations and into mature forests.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Travel in avalanche
terrain is not recommended during this period.
Consult http://www.idahopanhandleavalanche.org/ or www.avalanche.org
for more detailed information.
Similar avalanche danger may exist at locations outside the
coverage area of this or any avalanche center.

The following message is transmitted at the request of Flathead Avalanche
Center Hungry Horse MT.
...AVALANCHE WARNING ISSUED BY THE FLATHEAD AVALANCHE CENTER...
07:00 MDT Mon Mar 24 2025
The Flathead Avalanche Center in Hungry Horse has issued a BACKCOUNTRY
AVALANCHE WARNING for the following areas:
NWS Missoula MT -
MTZ001 (MTZ001)...MTZ002 (MTZ002)
* WHAT...Heavy snow, powerful winds, above-freezing temperatures, and rain
have combined to create very dangerous avalanche conditions.
* WHERE...All elevations of the Whitefish, Swan, and Flathead Ranges, and
the Lake McDonald and Marias Pass areas of glacier National Park.
* WHEN...In effect from Mon 07:00 MDT to Tue 07:00 MDT.
* IMPACTS...Below about 6500 feet, rain on recent snow has created
widespread wet snow avalanche hazards. Above this elevation, unstable slabs
of new and drifted snow have formed. Large natural wet snow avalanches are
likely; large to very large dry slab avalanches are likely.
* PRECAUTIONARY / PREPAREDNESS ACTIONS...Very dangerous avalanche
conditions. Avalanches may run long distances, run through treed slopes, and
entrain destructive amounts of debris. Travel where avalanches start, run,
or stop is not recommended.

...RISES EXPECTED ON RIVERS AND STREAMS THURSDAY INTO THIS WEEKEND...
Temperatures in the 60s and 70s through Wednesday will increase snow
melt of the mid and high elevation snow pack. This will be followed
by mountain rain Wednesday night through Friday. Saturated mountain
soils will allow for efficient runoff and will increase water levels
on mountain rivers, creeks and streams.
The primary concern is the John Day River at Service Creek which is
forecast to reach minor flood stage Thursday morning through Friday
afternoon, peaking early Friday morning. The Grande Ronde River at
Troy and the Naches River at Cliffdell and Naches are expected to
reach action stage Wednesday afternoon through at least Friday
morning but have a low probability of reaching minor flood stage.
Several other rivers are forecast to approach but not quite reach
action stage. Smaller creeks and streams may also have significant
rises but at this time they do not appear to reach levels that would
cause flooding.
People with activities near creeks and streams should exercise
caution as flows will be swift and very cold water can quickly lead
to hypothermia if someone were to fall into the water.
Those with interests along rivers, creeks and streams should
continue to monitor forecasts as there is some uncertainty in the
expected water levels. Stay tuned to for the latest forecast updates
along with any flood warnings or advisories that may be issued.

...Warm Temperatures this Week May Lead to Flood Impacts from
Efficient Low and Mid Elevation Snowmelt...
Temperatures today through Thursday will be well above averages,
increasing low and mid elevation snowmelt and runoff. Standing water
in typical low spots may occur, but we`ll also likely begin seeing
the swelling of smaller creeks and tributaries that feed the larger
streams and rivers. This may even push some streams and creeks above
bankfull causing minor flooding and bank erosion due to the higher
flows.
The warm temperatures will peak Wednesday with afternoon highs
reaching above 60s and some locations in the South Hills and lower
Snake Plain getting above 70 degrees. These will be the warmest
readings of the year, thus far and will likely challenge daily
records. While daytime high temperatures will garner most of the
attention, the warm overnight low temperatures will likely remain
well above freezing through Thursday, exacerbating snowmelt through
the overnight hours.
A cooldown is forecast to arrive late in the week with temperatures
Friday and Saturday dipping back down towards normals, and overnight
lows back to near freezing by Saturday morning. This cooldown,
however, will be accompanied by increasing rain chances which could
add to the runoff concerns.
Stay away from fast moving water, swollen river banks and never
attempt to cross flowing water over roadways.

...HIGH ELEVATION SNOWMELT WILL CAUSE RISES ON RIVERS, CREEKS,
AND STREAMS POTENTIALLY LEADING TO MINOR FLOOD IMPACTS THROUGH
MIDWEEK...
Warmer temperatures will lead to snowmelt, causing rises on
rivers, creeks, and streams across southeast Oregon through
midweek. Saturated soils in some areas will increase runoff.
Those with interests along rivers, creeks and streams should
continue to monitor the forecast as there is some uncertainty in
how much response the lower elevation rivers, creeks and streams
will see. Stay tuned to the forecast for the latest updates, along
with any warnings or advisories that may be issued.
