Wind gusts in excess of 100 mph expected over Sierra
October 13, 2016
RENO, Nev. — The National Weather Service issued multiple watches and warnings along the Sierra's eastern front Thursday ahead of a series of powerful storms expected to bring rain, high-elevation snow, strong winds and increased fire danger to western Nevada through the weekend.
The winds, combined with low relative humidity, triggered red-flag warnings Thursday afternoon stretching from Mineral and southern Lyon County southeast of Reno to as far south as the Las Vegas area and southwest Lincoln County.
Gusts in excess of 100 mph are expected over Sierra ridge tops beginning Thursday night, with sustained winds up to 35 mph and 65 mph gusts in the valleys around Reno and Carson City, the weather service said.
"Even though summer has passed, the potential for extreme fires is still just as high," Reno Fire Chief Dave Cochran said Thursday.
Another round of severe weather is expected to bring snow to upper elevations of the Sierra on Saturday into Sunday, including on U.S. Interstate 80 over the Donner Pass near Truckee, California. Wind gusts on the tops of mountains there could reach 125 mph, the service said.
Up to 4 inches of rain is forecast in the Sierra, and about a half-inch in Reno into Sunday. Wind-blown waves could reach 6-feet high on Lake Tahoe.
