After Snow-Free Winter, Everest Weather Weirdness Continues - BBC

Already experiencing melting glaciers and a receding snowline, the Everest region of Nepal has seen some unusual weather patterns these past few months. It has given locals further cause to examine the changing face of this unique environment.

A snow-free winter, followed by unexpected snow storms in the second week of March - when spring had already begun - has left Sherpas baffled.

Another unexpected storm in April, which lasted three days, surprised the locals further still. The following morning, on 21 April, debris from a major ice collapse killed three Sherpa climbers and injured more than a dozen others in the Khumbu Ice Fall area. Such accidents are not uncommon in mountaineering, but this one was blamed on the unusual snowfall which was believed to have caused the collapse of the ice mass.

EDIT

Even local Sherpas say heavy snowfall in spring is something they are not used to. Moreover, the snowstorms occurred after a completely dry winter period, lasting from November to February. "Last winter was not at all like winter, and now the same is the case with spring," said Jangbu Sherpa, an 80-year-old Sherpa from mountain town Namche, which is en route to the Everest base camp.
