Ski areas are rejoicing after the first winter storm of the season made its way into the Lake Tahoe Basin on Thursday.

A winter storm warning remains in effect through 11 a.m. today, according to the National Weather Service. Once all is said and done, accumulations are expected to reach between 6 to 14 inches at lake level and 1 to 2 feet above 7,000 feet.

The storm forced chain controls on all mountain passes Thursday, and several accidents were reported.

According to the California Highway Patrol, 12 accidents were reported. Nine of them were collisions.

Three of the crashes involved injuries, one being by Bliss State Park and two by Sierra-at-Tahoe.

Two or three crashes occurred on Highway 50 with no significant injuries involved.
