SACRAMENTO (AP) -- Water from the rain-swollen Sacramento River is spilling over a 33.5-foot-high concrete wall and into a bypass built to divert flood water.
NOAA hydrologist Robert Hartman said Sunday the overflow is expected to reach a depth of three feet on Tuesday then start receding.
It's the first time water has spilled over the so-called Fremont Weir crest and into the Yolo bypass since 2012. The nearly 2-mile-long concrete wall is located about 8 miles northeast of Woodland.
The bypass is an expanse of farmland and natural habitat that stretches from Sacramento to Davis and was created a century ago.
Beachgoers are warned of powerful surf along the Central and Southern California coast.
The National Weather Service said Sunday that waves up to 8 feet will pound many beaches for most of the day.
A high surf advisory is in effect in Santa Barbara, Ventura and Los Angeles counties.
Meanwhile a wind advisory has been issued for some coastal areas and in the mountains and high deserts.
A storm dumping rain in much of Northern California is expected to weaken as it moves south, though the southern part of the state could see scattered showers or drizzle.
