Exceptionally high tides will swamp California. Here's when

Exceptionally high tides are set to hit California as early as this weekend, sending officials scrambling to prepare for another onslaught along the state's already battered coast. The National Weather Service issued a coastal flood warning that goes into effect Sunday morning and lasts through Thursday afternoon, saying it expects "significant coastal flooding" in San Diego and Orange counties that will inundate low-lying homes, businesses and critical infrastructure, with some shoreline erosion in the morning throughout the warning period. Significant-to-moderate beach erosion is likely in Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties, and "isolated damage of structures due to sea water inundation is possible," forecasters said. A coastal flood advisory has been issued over the same time period in those four counties. "Take the necessary actions to protect flood-prone property," the weather service said.
