Shivering Shamrocks: A Saint Patrick’s Day Storm
The National Weather Service has issued a Winter Storm Warning for the western slope of the northern Sierra Nevada, until 11 PM tonight (St. Patrick’s Day). Additionally, a Winter Weather Advisory is also in effect for Yosemite National Park (above the Valley floor), through 11 PM tonight.
Heavy snow remains in the forecast for elevations above 4,500 feet.
The heaviest snow is expected early this morning, with snowfall rates of up to two to three inches per hour at times.
The snow levels may fall to around 3,500 feet by this evening. Light snow accumulations of one to three inches is possible above 3,500 feet. Additional snow accumulations above the 4,500 foot elevation, will range between three to ten inches. The higher you go, the more the snow.
Winds may continue to gust as high as fifty to fifty-five mph. Such strong winds could cause extensive tree damage and bring down tree branches.
Slow down and use caution while traveling. In fact, persons should delay travel if possible as travel in the upper elevations could be very difficult to impossible. If travel is absolutely necessary, drive with extreme caution and be prepared for sudden changes in visibility. Consider taking a winter storm kit along with you and anything else that would help you survive in case you become stranded.
