Recent Avalanches: There was an avalanche fatality near Lake George, outside our forecast areas, on Friday. Within our forecast areas, we did not receive any reports of human-triggered avalanches over the weekend. Last weekend, there were many human-triggered avalanches at the interface with the latest storm snow about 1' deep, including one accident with a skier fully buried and injured on Max's and some remotely triggered avalanches.
Since the last storm on March 18-20th, we have seen mostly clear skies, cold temperatures with solar warming in the afternoon, and relatively light winds. Despite this lack of recent weather input, there are still a few weak layers in the upper 2' of the snowpack that we are concerned about, which could cause human-triggered avalanches. At this point, we expect these avalanches to be stubborn to trigger, but due to the persistent weak layers involved, it is possible to trigger an avalanche with no warning signs beforehand.
You can always avoid this hazard by sticking to lower-angle slopes. However, if you get into avalanche terrain, we recommend carefully considering the runout and avoiding any terrain traps like cliffs, gullies, or trees that could increase the consequences if you get caught off guard and trigger an avalanche on one of these buried weak layers. Of course, we always recommend travelling one at a time in avalanche terrain, spotting your partners, and grouping up in a safe zone to limit your group's exposure to avalanche hazards.
Loose Snow Avalanches remain likely in steep terrain. These will be easy for a person to trigger, and can be a concern in consequential terrain. With partly cloudy skies expected today, it is unlikely we will see significant natural activity.
