Fatal Avalanche Strikes Yalung Ri Base Camp Amid Severe Himalayan Weather

A devastating avalanche struck the base camp of Mount Yalung Ri in Nepal on Monday, November 3, 2025, resulting in the confirmed deaths of seven individuals. The incident occurred around 9:00 a.m. local time, sweeping through the encampment situated below the 5,630-meter summit where a guided expedition was positioned. Fatalities included climbers from the United States, Canada, and Italy, as well as essential members of the Nepali guiding team.

Immediate rescue efforts were severely hampered by ongoing, relentless adverse weather conditions. Heavy, persistent snowfall and powerful, gusting winds made any aerial deployment, including helicopter evacuations, impossible in the aftermath. This critical delay in accessing the site significantly amplified the gravity of the situation for those involved and the wider expedition community.

In response to the tragedy, authorities have issued immediate and elevated warnings across the entire Rolwaling Valley region encompassing the fatal ascent. These advisories stress the current, highly unstable nature of the snowpack, urging extreme caution for any high-altitude endeavors in the area. The focus is now shifting toward a comprehensive understanding of the factors that contributed to the disaster.

Recent mountaineering reports indicate that the 2025 season had already been marked by unusual weather. Meteorological data showed that pre-monsoon snow accumulation in the central Himalayas was nearly 30% higher than the ten-year average, establishing a precarious foundation. This heightened snow load, combined with specific wind shear typical for early November, likely created the conditions for a slab failure, a critical element in the assessment of the event.

The Yalung Ri region, while remote, demands profound respect from mountaineers, as its isolation inherently extends rescue response times even under favorable conditions. This somber occurrence serves as a stark reminder of the delicate balance required when engaging with formidable landscapes. The collective response, involving international and local support, underscores a commitment to assisting affected families and ensuring that the lessons learned guide future decisions in the high mountains.
