High Surf Warning issued November 13 at 5:57PM PST until November 15 at 4:00AM PST by NWS San Francisco CA
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.
