As time goes on, weather models are looking more favorable for what could be an extended period of snow in the Cascades and Olympics beginning somewhat this weekend. With southerly flow at times the first day or two snow levels could go up for a while west of the Cascades but that is not a certainty.

If it doesn't warm up, avalanche hazard could ramp up rapidly as the cold clear weather of late will have resulted in sugary snow near the surface (I haven't been out, but an icy layer may be below this up to a certain elevation). In any case new snow is not likely to bond well and as accumulations increase after the weekend it may be surprisingly avalanchy given the low snow depths thus far.

Watch the NWAC Avalanche forecasts as this (hopefully) period approaches.

The current snowpack (and in some areas the lack thereof) requires close attention after a strong snowstorm moves in Tuesday. Where there is current snowpack the bond will be poor and elevated and unusual concern should continue depending on how high snow levels get during storms later in the weak. Near the crest, for instance, it may be possible for deep slabs notably during storms but between them as well. All of this depends on the existence of current snowpack that has been exposed to nearly a week of cool clear weather and on whether it gets warm enough during storms in some areas to reduce the problem layers back to something nearer normal Cascade conditions. The Olympics are likely to have significantly different conditions than the Cascades.

Watch NWAC forecasts and follow telemetry to see how warm it has gotten during these storms as you plan travels.

The bottom paragraph is the key paragraph in this current NWAC avalanche forecast.

Canadian snowpacks and possibly crest and east side Cascade snowpacks could remain weak for a very long time (depending).
