Tuckerman Ravine has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised.
A General Advisory is currently issued for Huntington Ravine. We are done issuing daily avalanche forecasts for Huntington for the remainder of the season. You will need to do your own snow stability assessments when using avalanche terrain in Huntington Ravine. A danger of falling ice exists and will persist until it all comes down.
After a stretch of very busy days with sunny summer-like weather, Mt. Washington has begun to fall under the shadow of lowering clouds. This is the result of a warm front heading our way, which will bring with it some winds on the front end and precipitation beginning this afternoon. Summit temperatures are currently below freezing so there is a chance it will start as a mix of snow, ice, and rain but it will transition to all rain. If this information puts you into a bad mood, try thinking of the positive side of things. For example, we’re forecasted to get well under a half inch of water equivalent by tomorrow morning. Compare this to the 3.5″ that fell early last week. It’s kind of like finding a marshmallow bunny that’s been hiding under your couch since the weekend–you’re not really sure why you should be happy about it, but you smile and eat it anyway. Unfortunately, there is nothing in the weather forecasts to indicate a return of sunny weather any time soon.
Today, as well as through the week, springtime hazards will continue to blossom. These have grown substantially in the past week, with conditions changing dramatically from day to day. Icefall has been a huge concern and will continue over the next few days as warm temps and incoming rain help send large chunks of ice to the floor of the Bowl. A tremendous amount of ice still hangs in the Sluice as well as in the Center Headwall, so don’t linger below this looming hazard. At this point in the season Lunch Rocks is the most likely place to get hurt or killed by falling ice. Crevasses have also begun to emerge and you’ll need to keep a watchful eye for them as you hike up your intended line of descent. The Lip and Headwall area have the greatest number of cracks opening up. What you see on the surface is often much smaller than the opening underneath the snow, so give them plenty of space and travel carefully around the edges to avoid punching through.Undermined snow increased dramatically over the past week as temps stayed above freezing for a full week before they finally dipped below freezing. Huge volumes of water coursed below the snowpack creating issues in a number of areas. Trying to ski/ride from the Bowl down to Hermit Lake is now akin to gambling with your life. Large sections of snow have been collapsing into the river. On Saturday one lucky skier went for a cold swim and was able to be pulled out by another person, and this was just trying to walk back through the woods to Hermit Lake. Do yourself a favor and walk down to Hermit Lake when leaving the Bowl. There are still plenty of turns to be had on the mountain but visitors need to be on high alert for the springtime hazards that have killed and injured many people over the years. When choosing your lines or your resting spots make sure you assess which hazards you face and develop a plan for dealing appropriately.
The Lion Head Winter Route is open as is most of the John Sherburne Ski Trail. The bottom section of the trail is now closed and you’ll need to watch for bare spots throughout the remainder. Cross over to the Tuckerman Ravine Trail at the rope to keep out of the mud and protect the trail from erosion. The Harvard Cabin is closed for the season leaving Hermit Lake Shelters as the only camping option on the east side of Mt Washington.
