Beach Hazards Statement


Coastal Hazard Message
National Weather Service San Francisco CA
1131 AM PDT Mon Sep 27 2021

...Increasing risk of large shore break, wave run up, and rip
currents from late Monday night to late Tuesday night...

.After a fairly quiet summer in terms of swell, the first larger
northwest swell of the season will arrive tonight. Expect an
increased risk of moderate to large breaking waves and stronger
rip currents. Additionally, increasing winds behind a cold frontal
passage in combination with the building swell may cause waves to
run up farther along area beaches than usual. This hazard is
primarily for west to northwest facing beaches. Caution is urged.
Northwest swell will gradually subside on Wednesday.

1131 AM PDT Mon Sep 27 2021

...BEACH HAZARDS STATEMENT IN EFFECT FROM 11 PM PDT THIS EVENING
THROUGH TUESDAY EVENING...

* WHAT...Northwest swell 8 to 10 feet at 13 to 15 seconds
  expected. Breaking waves of 13 to 17 feet possible.

* WHERE...West to northwest facing beaches along the Central Coast
  from Sonoma County through Monterey County including but not
  limited to; Ocean Beach, Montara State Beach, and Marina State
  Beach.

* WHEN...From 11 PM PDT this evening to 11 PM PDT Tuesday
  evening.

* IMPACTS...Increased risk of moderate to large breaking waves,
  strong rip currents, and wave run up.

* ADDITIONAL DETAILS...People walking along the beach should never
  turn their back to the sea. Avoid fishing from rocks or jetties.
  The coastal waters remain cold. Cold water shock may cause
  cardiac arrest and it also can cause an involuntary gasp reflex
  causing drowning, even for a good swimmer. The surf zone will be
  dangerous due to larger breaking waves and strong rip currents.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Remain out of the water to avoid hazardous swimming conditions.

WINDS: Strong and gusty southwest winds are expected through
tonight, turning northerly and becoming more breezy Tuesday as a
cold front moves through. Plan on impacts to air/road travel,
choppy lake conditions, areas of blowing dust, and increased fire
danger.

TEMPERATURES: Temperatures will fall around 20 degrees by
Tuesday-Wednesday. This will likely result in the coldest high
temperatures the region has experienced since May. Sub-freezing
temperatures are expected for rural and suburban lower valleys
Wednesday morning, possibly a few degrees colder than what we saw
Monday morning last week. Lows could easily dips into the teens
for colder Sierra valleys.

RAIN AND SNOW: Best chances for rain will be tonight in the
northern Sierra, northeast California, and far northern Washoe
County, but even here liquid amounts will be rather meager.
Lighter showers are possible as far south as Hwy 50 in the Sierra
and I-80 in western Nevada. A mix of snow is possible down to
around 6500 feet elevation, but it`ll be hard to see accumulation.
