How an 'Off the Charts' Everest Blizzard Trapped Hundreds
"About 900 trekkers and guides were rescued in the days after the storm, according to the Associated Press. These individuals were trekking to and around the base camp on the mountain's north side in Tibet during China's National Day and Mid-Autumn Festival holiday break. In Nepal the precipitation fell as rain, causing widespread flooding and landslides that killed at least 47, according to Al Jazeera."
"The heavy blizzard dropped around three feet of snow in the Gama Valley of Tibet last Friday and Saturday, according to reporting. This came during a period that is typically dry and mild in the region. The rainy monsoon season in Tibet and Nepal runs from May to mid-September. Most climbers try to summit Everest in the spring, before the monsoon begins. The few climbers who do attempt the peak in October are lured by smaller crowds and typically clear skies."
A rapid blizzard on the north side of Mount Everest dumped an unprecedented amount of snow in a 12-hour period, 3.5 times greater than any recorded in six years of station data. The storm produced about three feet of snow in Tibet's Gama Valley during a normally dry, mild October window outside the monsoon season. About 900 trekkers and guides required rescue after becoming trapped near base camp during China's holiday break. In Nepal the system produced rain that triggered widespread flooding and landslides, killing at least 47 people. The event represents an extreme, out-of-season meteorological anomaly.
