Forecasters say the brunt of the next storm will be felt in Alpine and Mono counties, still recovering from the last bout of storms.
A winter storm watch has been issued from Monday through Wednesday morning for the length of the Sierra Nevada.
Snow accumulations of 3-9 inches along the Highway 395 corridor with 2-3 feet in the Sierra above 8,500 feet.
Today is forecast to be warm and dry ahead of a front due to arrive on Sunday.
“Simulations have trended toward lower liquid and snow totals for the Sierra, but still enough to lead to Sierra travel impacts as snow levels fall below 6,000 feet. Shadowing and lack of moisture depth will really limit rain or snow totals to Western Nevada,” forecasters said on Saturday morning.
Next week’s storm is expected to strike further south.
“Given the more southern track, there appears there will be a break Monday and Monday night with heaviest snowfall now expected to arrive Tuesday,” said National Weather Service Reno Meteorologist Wendell Hohmann.
Snow levels are expected to drop to near the valley floors in Western Nevada by Tuesday.
Because snow levels will be so low, there will be less chance of flooding as a result of the storm.
The Humboldt-Toiyabe National Forest is warning winter recreationists that conditions are right for avalanches and flooding on National Forest System lands in Nevada and eastern California due to recent rain-on-snow events and warmer temperatures.
“When rainfall coincide with seasonal snow cover, the runoff of water can be much greater than what is produced from rain or snowmelt alone,” explained Forest Supervisor Bill Dunkelberger. “Also, the snowpack becomes heavier and more unstable, which increases the likelihood of an avalanche occurring.”
