The National Weather Service says so-called King Tides — caused by a rather unique combination of how the sun, the moon and the earth align — will bring the highest tides of the year on Thursday, Friday and Saturday mornings. Along with the high tides, forecasters say a building swell will bring large breaking waves to area beaches. (AP Photo/Marcio Jose Sanchez)
