...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 6 PM PDT
SUNDAY...

* WHAT...Up to 1.5 ft of inundation above ground level is
  possible in low-lying areas near shorelines and tidal
  waterways.

* WHERE...Bayshore locations along the San Francisco Bay, San Pablo
  Bay, and Monterey Bay.

* WHEN...Until 6 PM PDT Sunday.

* 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. More substantial impacts are expected along bayshore
  Marin County where increased flooding is anticipated across
  low lying areas.

* ADDITIONAL DETAILS...At the San Francisco tidal gauge, high tide
  is expected to be 1.5 feet above normal (7.3 ft MLLW) at 03:44
  PM on Saturday 10/31 and 1.0 ft above normal (6.8 ft MLLW) on
  Sunday 11/01 at 3:59 PM. These predictions include up to 1.5 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

...ISOLATED WATERSPOUTS POSSIBLE TODAY ACROSS THE COASTAL
WATERS...

Scattered showers will continue across the coastal waters through
Sunday morning. With increasing instability and enhanced potential
for rotating storms, isolated waterspouts will be possible today,
mainly from the coastal waters off of the Santa Barbara Central
Coast southward to the inner waters south of Point Conception.
These same areas will also have a 5-10 percent chance of
thunderstorms today.

Waterspouts are dangerous and can capsize boats. Never move
closer to investigate or take photos. The best way to avoid a
waterspout is to move at a 90 degree angle to its apparent
movement.
