Sierra storm could bring 8 feet of snow; Reno may see rain, snow

Snow driving myths: Bigger vehicles aren’t always safer in winter

Trucks and SUVs may look winter-ready, but factors like weight balance, drivetrain and, most importantly, tires matter more than size alone.

A powerful winter storm is expected to move into the Sierra late Sunday, bringing heavy snow, strong winds and hazardous travel conditions across California and Nevada through much of next week.

Forecasters say 4 to 8 feet of snow could fall along the Sierra crest, including Donner Pass, making it the strongest system to hit the region since around Christmastime.

The heaviest snowfall is expected Monday afternoon, Feb. 16, through Tuesday, Feb. 17.

Winter storm watches are in effect from 10 p.m. Sunday, Feb. 15, through 10 p.m. Wednesday, Feb. 18, across the Sierra, including Donner Pass and the Greater Lake Tahoe area.

Up to 8 feet of snow possible at Donner Pass

Donner Pass and Interstate 80, along the west slope of the Northern Sierra, are expected to see the brunt of the storm.

Snow is forecast to begin Sunday evening, with heavy snowfall continuing into midweek, Feb. 15–18. At higher elevations along the Sierra crest, totals could reach 4 to 8 feet by Wednesday.

Winds could gust between 45 and 55 mph, with Sierra ridges seeing even stronger gusts. Combined with heavy snow, those winds may create periods of whiteout conditions.

Chain controls are likely along I-80, and road closures are possible during peak snowfall. Drivers planning to cross the Sierra for Presidents Day weekend are urged to travel before Sunday evening.

Winter storm watch issued for Lake Tahoe

The National Weather Service in Reno has issued a winter storm watch for the greater Lake Tahoe area from Sunday evening through Wednesday evening.

Heavy snow is expected across the Tahoe Basin, with 18 to 30 inches possible at lake level, highest along the West Shore and in Alpine County. Sierra totals could reach 2 to 5 feet.

Winds are forecast to gust 35 to 45 mph in valleys, with Sierra ridge gusts exceeding 100 mph.

The heaviest snowfall rates are expected late Monday afternoon through Tuesday afternoon. Travel could become very difficult to impossible at times, with whiteout conditions possible and strong winds capable of downing trees and power lines.

Residents and visitors are urged to monitor forecasts and consider delaying travel if possible.

What to expect in Reno

Reno is likely to start this system with rain before colder air moves in early next week.

Snow could reach the valley floor by Monday night, with a 25% to 60% chance of at least 2 inches in the Reno-Carson area. Foothill communities and Virginia City have a much higher likelihood of accumulating snow.

Even if totals in Reno stay lower than in the Sierra, periods of slick roads and slow travel are possible as the storm moves across the region.
