jonas hoke,

Small pockets of slab may be encountered if you venture high enough to find skiable conditions. Rugged travel in the valley bottoms means it will take some effort to get there though. Skitter with increasing caution as you transition below treeline.

Summary

Weather Forecast

A weak Aleutian Low moves toward our area this evening.  Sadly it isn't bringing enough snow with it to improve the skiing.

Today: Sunny with increasing cloud. Alpine High -10 C. Ridge wind light SW.

Tonight: Mainly cloudy, isolated flurries. Alpine Low -11 C.

Tuesday: Mainly cloudy, isolated flurries. Alpine High -10 C. Ridge wind light SW.

Snowpack Summary

Outflow Northerly wind has loaded what little snow is available for transport in to lees. Last weeks storm gave heavy rain as high as 2400m, and over 50cm of snow accompanied by extreme W winds at upper elevations. The storm ended with a rapid cooling trend; refreezing the saturated snowpack and leaving a dusting of 5-10cm on the crusted surface.

Avalanche Summary

No new avalanches have been observed or reported.

A significant loose wet avalanche cycle occurred with the last storm with slides up to size 3; the debris from this is now refrozen and presents a significant hazard to skiers.

Confidence

Due to the number and quality of field observations

Problems

Wind Slabs

An icon showing Wind Slabs

Reverse loading from outlfow winds has built small pockets of windslab in immediate lees. These sit on a firm crust below 2400m.

  • Use safe ski cutting techniques to enter your line.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
