内华达山脉周五起迎冬季风暴：6,000英尺以上或降6至12英寸雪，阵风达每小时50英里
美国国家气象局 Hanford 办公室11月10日上午9时30分发布冬季风暴观察，并于当天下午5时31分更新：位于加利福尼亚州的内华达山脉高海拔地区，将从11月14日周五下午起迎来一场冬季风暴，观察持续到11月17日周一深夜。
这次观察覆盖的区域包括优胜美地国家公园山谷以外地区、San Joaquin 河上游、Kaiser 至 Rodgers Ridge 一带，以及 Kings Canyon 国家公园、Grant Grove 和 Sequoia 国家公园。气象局预计，海拔6,000英尺以上地区可能降下大雪，积雪可达6至12英寸，阵风最高每小时50英里。
气象局警告，这样的降雪加上强风，会让山区出行变得非常困难，甚至无法通行。计划在本周末前往内华达山脉国家公园和高山公路的游客，应提前留意最新预报与道路状况，必要时调整行程。
内华达山脉是加州重要的降雪区，冬季风暴带来的积雪既是山区交通的挑战，也是加州水资源的重要补给。气象局将随风暴临近更新预报。

Winter Storm Watch for the Sierra Nevada: 6 to 12 Inches of Snow Possible Above 6,000 Feet Starting Friday
The National Weather Service office in Hanford issued a Winter Storm Watch at 9:30 a.m. PST on November 10 and updated it at 5:31 p.m. the same day: the high country of California's Sierra Nevada will see a winter storm beginning Friday afternoon, November 14, with the watch running through late Monday night, November 17.
The watch covers Yosemite National Park outside the valley, the Upper San Joaquin River, Kaiser to Rodgers Ridge, Kings Canyon National Park, Grant Grove and Sequoia National Park. The Weather Service expects heavy snow to be possible above 6,000 feet, with accumulations of 6 to 12 inches and wind gusts as high as 50 mph.
The agency warns that snow of that amount, combined with strong winds, could make mountain travel very difficult to impossible. Anyone planning to visit Sierra Nevada national parks or high-country roads this weekend should check the latest forecast and road conditions and be ready to change plans.
The Sierra Nevada is California's most important snowpack region: winter storms challenge mountain travel, but they also deliver a large share of the state's water supply. The Weather Service will update the forecast as the storm approaches.
