A massive and sudden blizzard on Mount Everest’s Tibetan slopes trapped nearly 1,000 hikers in remote camps during China’s National Day holiday weekend, according to state media reports.

Reuters and Jimu news reported Sunday that at least 350 people have so far reached safety, while contact has been made with several hundred others still stranded in the snowbound region.

The storm struck Friday, dumping heavy snow and rain across the Himalayas, reports said. 

The worst conditions came near the eastern Kangshung face of Everest, in Tibet’s Karma Valley, where elevations average over 13,779 ft.

Authorities suspended ticket sales and closed entry to the Everest Scenic Area on Saturday evening, according to the Tingri County Tourism Company’s official WeChat account. 

It remains unclear whether trekkers on the north face of Everest, also located in Tibet but more easily accessible by road, were impacted by the same weather system.

The extreme weather has also battered neighboring Nepal, where heavy rains have triggered landslides and flash floods, killing at least 47 people since Friday. 

Thirty-five people died in separate landslides in the eastern Ilam district near the Indian border, while others remain missing after being swept away by floodwaters, per Reuters.
