## extract

Coastal Flood Advisory — San Francisco; Northern Monterey Bay; Southern Monterey Bay and Big Sur Coast
Severity: Minor. Certainty: Likely.
* WHAT...For the 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, increased risk of rip currents and sneaker waves
expected with breaking waves up to 16 feet.

* WHERE...San Francisco, Northern Monterey Bay and Southern
Monterey Bay and Big Sur Coast Counties.

* WHEN...For the Coastal Flood Advisory, until 3 PM PDT Tuesday.
For the Beach Hazards Statement, through Monday evening.

* IMPACTS...Flooding of lots, parks, and roads with only
isolated road closures expected. High tides will result in
flooding along coastal trails, cut off access to some low-
lying beaches and coastal areas, and bring water and waves
farther up the beach than typical. Dangerous conditions are
forecast along the shoreline. Hazards include sneaker waves,
strong rip currents, and large breaking waves.

* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high
tide is expected to be 1.5 ft above normal (7.3 ft MLLW) at
12:18 PM Sunday 10/11, 1.2 ft above normal (7.1 ft MLLW) at
12:46 PM Monday 10/12, and 1.1 ft above normal (7.0 ft MLLW)
at 1:14 PM Tuesday 10/13. These predictions include up to 1.2
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.
