Huntington Ravine currently has MODERATE avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Unstable slabs are possible on steep terrain. Use caution in steeper terrain.
The summit picked up 8.4 cm (3.3 in) of new snow in the last 24 hours with high W and WNW winds. Snow changed from heavy and wet to a lighter density as the temperature dropped and was interspersed with periods of small hail and heavily rimed crystals. These conditions have likely created some interesting new windslab over the old surface especially on E and ESE aspects. While snow fell the winds hovered in the 110-130 kph (70-80 mph) range. These strong winds deposited snow lower down into the ravines and we expect to see thicker windslab in the middle to lower sections of slopes and gullies. Winds are forecasted to remain strong today and shift to the NW which will continue to load and crossload other aspects. As this happens you should expect to see SE aspects approach the upper end of their current danger rating.
The John Sherburne ski trail has variable conditions due to the recent changes in temperature and precipitation. Expect variable conditions with areas of ice, some blowouts, abrupt water bars, open holes, and running water.
THE LION HEAD WINTER ROUTE IS OPEN. This is a steep and challenging route. Ice axe, crampons, and the skill to use them well are necessary for safe travel. Remember, it is always easier to go up than come down.
AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in reading mountain weather's effect on the snowpack, and avalanche rescue.
