High Surf Warning

* WHAT...For the High Surf Warning, dangerously large breaking waves of 25 to 35 ft, with occasional sets of 40 to 50 ft at favored breakpoints. For the Coastal Flood Advisory, large breaking waves will run up beaches and crash over seawalls, inundating adjacent, low-lying infrastructure.

* WHERE...All Pacific Coast Beaches.

* WHEN...For the High Surf Warning, until 4 AM PST Sunday. For the Coastal Flood Advisory, from midnight tonight to 6 PM PST Saturday.

* IMPACTS...High tides will result in flooding of low-lying infrastructure, isolated road closures, and coastal erosion. Rising tides will bring water and waves farther up the beach than normal, restricting escape from beaches and coastal areas. Dangerously large breaking waves can overpower swimmers, pulling people into the sea from beaches, jetties, and rocks resulting in significant physical injury and increasing the risk of drowning. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks.

* ADDITIONAL DETAILS...The Coastal Flood Advisory on Saturday is specifically for the Pacific Coast, where large breaking waves will spill over sea walls and run up beaches onto adjacent infrastructure.
