Weather Alert in Idaho
Avalanche Watch issued February 16 at 6:24AM MST by NWS Pocatello ID
AREAS AFFECTED: Bear River Range
DESCRIPTION: AVAPIH * WHAT...Avalanche watch. Heavy snowfall and strong winds are expected to rapidly increase avalanche danger across northern Utah and southeast Idaho beginning Tuesday and continuing throughout the week. Expect dangerous and complex avalanche conditions to develop on many slopes, with large and natural and human- triggered avalanches likely. * WHERE...The Bear River Range and Wasatch Mountains. * WHEN...6 AM MST Monday through 6 AM MST Tuesday * IMPACTS...Dangerous avalanche conditions are expected to develop on many slopes. Avalanches can be triggered on slopes steeper than 30 degrees. They may also be triggered remotely from a distance or from below.
INSTRUCTION: Avoid traveling on or underneath steep terrain at mid and upper elevations in the backcountry. Carry and know how to use avalanche rescue equipment, including a transceiver, shovel and probe. Find safer riding conditions on slopes less than 30 degrees with no overhead hazard. Consult www.utahavalanchecenter.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.

Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.

Cirrocumulus clouds form at high altitudes (usually around 5 km)
and have distinguishing characteristics displayed in a fine layer of
small cloud patches. These small cloud patches are sometimes referred to as
"cloudlets" in relation to the whole cloud formation.
Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the
water droplets in the cloud freeze into ice crystals and the cloud becomes a
cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud
formations generally pass rapidly.
