Parts of the Sierra Nevada could get up to a foot of snow on the highest peaks this weekend, with Lake Tahoe, Yosemite and the mountain stretches of Interstate 80 and Highway 50 all under advisories.

The National Weather Service issued Winter Weather Advisories on Thursday, Oct. 29, for much of the Sierra Nevada. Three NWS offices, in Sacramento, Reno and Hanford, put out the alerts, and all of them run from 8 a.m. PDT on Saturday, Oct. 31, to 7 a.m. PST on Sunday, Nov. 1.

The end time is in standard time because daylight saving time ends at 2 a.m. Sunday, in the middle of the storm.
