High Surf Warning issued November 13 at 3:44AM PST until November 15 at 4:00AM PST by NWS San Francisco CA
* WHAT...For the first Coastal Flood Advisory, Up to 1.5 ft of
inundation above ground level is possible in low-lying areas
near shorelines and tidal waterways. For the Beach Hazards
Statement, An increased risk for sneaker waves and strong rip
currents with breaking waves of 15 to 20 ft expected. 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 second Coastal Flood Advisory, large
breaking waves will run up beaches and crash over seawalls,
inundating adjacent, low-lying infrastructure.
* WHERE...San Francisco and Southern Monterey Bay and Big Sur
Coast.
* WHEN...For the first Coastal Flood Advisory, until 4 PM PST
today. For the Beach Hazards Statement, through this afternoon.
For the High Surf Warning, from 6 PM today to 4 AM PST Sunday.
For the second 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...At the San Francisco tide gauge, high tide
is expected to be: 1.5 ft above normal (7.3 ft MLLW) at 12:49 PM
today 11/13. These predictions include up to 1.8 ft of surge
that will enhance the astronomical tide and flooding threat.
High tide varies up to 90 minutes earlier or later along the
Pacific Coast and through the San Francisco Bay, respectively.
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.
If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.
Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
