General Spring Avalanche Statement

We have stopped issuing daily avalanche advisories for the 2017-2018 season. A big thanks to all who supported the avalanche center this season. Avalanche activity will invariably occur this spring. Continued daily wet snow melt-freeze cycles will occur and additional storm cycles may impact the forecast area. Some information and resources to aid in trip planning and decision making have been assembled on the advisory page.

Periods of intense April sun this morning may cause enough warming for some small loose wet instabilities to form in isolated areas. MODERATE avalanche danger would result from this expected warming. If the forecasted cloud cover materializes sooner than expected, loose wet instabilities may be unlikely and less avalanche danger would exist.

April 18, 2018 at 6:56

MODERATE avalanche danger could exist at all elevations today due to periods of sunshine causing rapid warming of the recent snow. Any amount of April sun could cause conditions to change in a matter of minutes and allow loose wet avalanches to become possible on sun-exposed slopes. Once any signs of warming snow or wet snow exist it is time to move to colder aspects, lower angle slopes, or switch an activity that does not involve snow.

Avalanche danger is MODERATE near treeline and above treeline where another round of wind slab formation is expected to have occurred last night. Below treeline avalanche danger is LOW where triggering an avalanche on a regional scale is unlikely but not impossible. Persistent slab and loose wet avalanche problems have a high degree of uncertainty today.

MODERATE avalanche danger exists above and below treeline due to a combination of wind slab and persistent slab avalanche problems. Significant uncertainly exists regarding the persistent slabs due to a change in weak layer of concern, isolated distribution, and a lack of data. Do not let an absence of signs of instability below treeline create a sense of security that discounts the possibility of an isolated avalanche problem.

LOW avalanche danger exists at all elevations, but LOW danger does not mean no danger. An isolated persistent slab avalanche problem may still linger in a few areas. In the unlikely event that an isolated human-triggered persistent slab avalanche does occur, it could be large with significant consequences.

CONSIDERABLE avalanche danger exists at all elevations in areas that held snow cover prior to last night's snowfall. A combination of wind slab, storm slab, and persistent slab avalanche problems exist. Very large avalanches could occur below treeline. Complex and dangerous avalanche conditions exist. Powder fever could easily induce poor decision making today.

While the avalanche danger should remain LOW today due to the minimal snow accumulation expected, unstable snow may still exist in isolated areas due to lingering persistent slabs or very small pockets of newly formed wind slabs. If observations indicate that an isolated area of unstable snow may exist, choose different terrain. If more snow falls than forecasted, larger avalanche problems could exist and the avalanche danger could increase to MODERATE.

The avalanche danger remains LOW. Triggering an avalanche remains unlikely on a regional scale. LOW danger does not mean NO danger. Unstable snow may still exist in isolated areas due to lingering persistent slabs. Investigate the snowpack and determine if the persistent slab problem may still linger in your chosen area. If so or if you don't have enough data for a clear answer, chose a different area. Avalanche danger should increase tomorrow as a small storm impacts the area.
