LAKE TAHOE, Calif. (KGO) — The Sierra Nevada is covered in fresh snow for the holiday week, but with the reward comes risks.

Sports Basement was busier than usual Friday afternoon as skiers and snowboarders picked up rental gear. The Sierra Nevada got hit hard in the last 72 hours.

Tahoe-area marketing expert Kevin Cooper — known as “Coop” — says winter has arrived in Lake Tahoe.

“We went from zero to here grow, this last storm really did deliver.”

What had been dirt is now covered by a blanket of fresh snow, bringing with it dangerous roads.

“I-80 has been opened and closed from Nyack all the way to the Nevada border for over 12 hours in the last two days due to spin outs,” said Cooper.

If you’re making the trek from the Bay Area, give yourself plenty of time and don’t forget chains for your tires. Whether you’re in it for he beauty or the sport, this weekend is expected to hit the mark.
