NASA in cooperation with the U.S. Geological Survey is helping emergency planners in Southern California get a more complete picture of the increasing risk of coastal flooding by looking at the highest of tides —"king tides."

"King tide" is the informal term generally used to describe an exceptionally high tide, which most often occurs when the Moon and the Sun are aligned and their gravitational pull on the Earth is at its strongest. King tides can be just a few inches higher than normal, but when combined with other factors, they can have damaging effects.
