Avalanche Forecast - Presidential Range

<p>Watch out for undermined snow, deep snow holes, falling rocks, and refrozen, hard snow surfaces until all the snow is gone. Review the list of <a href="https://www.mountwashingtonavalanchecenter.org/springtime-mountain-hazards-3/" target="_blank" rel="noopener">spring hazards</a> in the forecast discussion and keep these in mind as you plan your day.&nbsp;</p> <p><strong>A section of the Tuckerman Ravine Trail through The Lip Area is <span style="color: #e03e2d;">CLOSED</span> to all use until the route is snow-free. </strong>This section extends from Lunch Rocks to the top of the Headwall where it meets the Alpine Garden Trail. Only this section of the trail is closed. This annual closure is due to the magnitude of the crevasses and undermining, along with the severe consequences of a fall in this area.<strong> (36 CFR 261.55(a))<br><br></strong><em>This is the final advisory of the season.&nbsp;</em><strong><br></strong></p>
