Santa Ana winds are expected to continue in L.A., Ventura counties

Santa Ana winds knocked out power to more than 1,000 homes in the San Fernando Valley late Sunday

Santa Ana winds that knocked out power to more than 1,000 homes in the San Fernando Valley late Sunday are expected to continue through early Tuesday in the mountains of Los Angeles and Ventura counties.

Gusts could reach 50 mph in more remote areas of Los Angeles County, and high tides and dense fog near the coasts could create hazardous conditions for smaller boats, the National Weather Service said.

Travelers on Tuesday should expect strong crosswinds, which can blow debris and tree limbs across roadways, knock down power lines and cause outages, the Los Angeles Department of Water and Power said.

A Santa Ana watch will also go into effect Tuesday in San Diego County.

One of the highest tides of the year hit California beaches Monday morning, with the Port of Los Angeles recording 61/2-foot waves. Called "king tides," they usually occur around the summer and winter solstices. Sunday was the day of the year with the fewest hours of daylight.

Residual effects will continue through Tuesday, including high surf and dangerous rip currents, the weather service said.

"The very high tides often cause coastal flooding when combined with high surf," meteorologist Bill Forwood said. "All the hazards of high surf are increased with the added effect of very high tides."

The current king tides season will bring extreme tides through Tuesday, then again Jan. 19-21 and Feb. 17-19.

Boats off the coasts of Los Angeles and Catalina Island should expect heavy fog late Monday and early Tuesday. Sailors "should be prepared for abrupt changes in visibility" and stay alert for exposed rocks and large vessels in the shipping lane, the weather service said.
