The National Weather Service issued a tide forecast Sunday, saying water levels near the Rio Vista bridge were expected to rise several feet due to King Tides.

"King Tides occur when the earth becomes aligned with the moon and the sun.  What this does is it pulls ocean water to the opposite sides of the earth. That creates the largest ranges of tides," meteorologist Craig Shoemaker said.

The NWS expected King Tides to hit the Bay area hardest, create extremely hazardous conditions at beaches until Tuesday.

Shoemaker told FOX40 the record water level under the Rio Vista bridge is 11.5 feet and the flood stage there is considered 11.9 feet. Monday, Shoemaker said the NWS expected to see the water there rise to 8 feet.

People visiting the waterfront were unimpressed by the King Tides.

"It's very calm. It doesn't look like there's very much action going on out here," Sam Ross said.

But Randy Hardesty said the water did look higher than normal.

"I can tell by the rocks and the pilings on the pier, the water marks on those," Hardesty said.
