Coastal Flood Advisory Issued for Areas in OC and SD

NEWPORT BEACH (CNS) - The highest tides are forecast tonight for the Orange and San Diego county coastlines, the National Weather Service said. 

So-called King Tides resulted in coastal flooding since Wednesday night when water breached a seawall on Balboa Peninsula causing street flooding. The National Weather Service in San Diego issued a Coastal Flood Advisory through 11 p.m. for areas susceptible to flooding during high tides, including Seal Beach, Sunset Beach, Newport Beach, Balboa, Oceanside Beach and Imperial Beach. 

The high tide at Newport Beach was forecast to hit 6.7 feet at 10:50 p.m. The tides were expected to hit 6.7 feet at 10:45 p.m. in La Jolla.``Low lying roads or parking lots near the water's edge may experience minor tidal overflow during the highest tide cycles,'' the NWS advisory reads. ``Minor flooding of roads occurred Wednesday evening in Newport Beach between 26th and 38th streets.''

``A Coastal Flood Advisory indicates onshore winds and/or tides will generate flooding of low areas along the shore, ''the NWS said.

``King Tide is a non-scientific term people often use to describe exceptionally high tides.,'' the National Oceanic and Atmospheric Administration said. ``Tides are long-period waves that roll around the planet as the ocean is 'pulled' back and forth by the gravitational pull of the moon and the sun as these bodies interact with the Earth in their monthly and yearly orbits. 

Higher than normal tides typically occur during a new or full moon and when the Moon is at its perigee, or during specific seasons around the country.''
