Friday Sneaker Waves

A Winter Storm Watch is in effect for much of interior NW California. Snow levels start around 4000 to 4500 ft Saturday night into Sunday, bringing possible impacts to the highest passes on Highway 3 and Highway 36 in Trinity County. Snow levels fall to 2000 to 2500 ft Monday night into Wednesday and could potentially be as low as 1500 ft in some areas. Many of the mountain passes could see accumulations. The valleys of Trinity County and perhaps Lake County could also see snow. If you must travel, check road conditions for any potential chain controls or road closures before leaving.

A large, long period swell will enter the waters Thursday night. This swell will create conditions that increase set behavior leading to an increased threat for sneaker waves for Northwest California. Remain safe while on the beach this Friday by choosing flatter beaches; staying off rocks, jetties, logs, and outcropping; and never turning your back to the ocean.
