Tonight's Supermoon brings high tides

SAN FRANCISCO (KTVU) - The King Tides are back- meaning high water and the possibility of flooding in low lying areas.

High tide is at 10:27 this morning. Water is lapping along the Embarcadero at Pier 14.

The King Tides are an informal name for an unusually high tide. They are regularly occurring and predictable.

According to the National Oceanographic and Atmospheric Association, higher than normal tides typically occur during a new or full moon and when the Earth is at it perigee- or closest to the moon.

Tonight we will see the Supermoon, the biggest and brightest moon of the year.
