RENO, Nev. — The first winter storm of the season dumped up to a foot of snow on the Sierra by Monday night and brought record rainfall to parts of northern Nevada, along with power outages and slippery roads blamed for several minor traffic accidents.
At least 12 inches of snow was reported in the southern Sierra near Mammoth Lakes, California, and up to 2 feet was possible in the upper elevations around Lake Tahoe by Tuesday, the National Weather Service said.
The record rain included nearly an inch of precipitation— .86 — at Reno-Tahoe International Airport and .67 of an inch at Winnemucca Airport about 160 miles northeast of Reno, the service said.
The total in Reno doubled the old record of .43 inch for the day set in 1940. Winnemucca's old record of .46 also dates to 1940. At Lake Tahoe, Glenbrook recorded 1.26 inches of rain mixed with snow and 1.13 inch of rain was reported at South Lake Tahoe, Calif.
Chains or snow tires were required on most mountain highways most of the day around Lake Tahoe as a cold front pushed east out of the central Pacific Ocean.
NV Energy reported power outages affecting more than 3,500 customers at Tahoe in Incline Village and about 1,500 in the Washoe Valley south of Reno Monday morning, but fewer than 1,000 were without power by noon.
Minor flooding was reported on local streets in Fallon about 60 miles east of Reno Monday morning but no serious damage was reported.
Stormy conditions were blamed for a three-car crash that temporarily closed the Mount Rose Highway in both directions between Reno and Tahoe Sunday night. Several spin-outs were reported on Interstate 80 and an SUV slid into a power pole on a city street in Sparks, but no serious injuries were reported.
The heaviest snow had moved south of U.S. Highway 50 by noon, the weather service said.
In eastern Nevada, a winter storm warning remained in effect through Tuesday morning in northern Elko County, with a winter weather advisory stretching into Lander and Eureka counties and a winter storm watch in northeast Nye County and White Pine County along the Utah line.
In southern Nevada, a wind advisory was in effect until 10 p.m. Monday in areas north and south of Las Vegas. A 66-mph gust of wind was recorded in Nye County at 11 a.m. Monday, the weather service said.
