Coastal Hazard Message
National Weather Service San Francisco Bay Area
147 PM PDT Mon Jul 2 2018

...Long Period Southerly Swell arrives early Thursday morning...

.Hurricane Fabio in the eastern north Pacific will generate a
moderate height, long period southerly swell train over the 
coming days. This swell train will move into the coastal waters of
the Monterey and San Francisco Bay areas early Thursday morning. 
The largest southerly waves are forecast to arrive late Thursday 
into early Friday.

...BEACH HAZARDS STATEMENT IN EFFECT FROM EARLY THURSDAY MORNING
THROUGH SATURDAY AFTERNOON...

The National Weather Service in San Francisco has issued a Beach
Hazards Statement for the entire coastline from Monterey to Sonoma
county, which is in effect from late Wednesday night through 
Saturday afternoon.

* WAVES AND SURF...Southerly swell 4 to 7 feet with a period of 
  16 to 18 seconds. 

* HAZARDS...Increased risk of rip currents and sneaker waves,
  stronger longshore current at west facing beaches, and somewhat
  larger breaking waves at south facing coasts.
 
* TIMING...Forerunners will arrive late Wednesday night through
  early Thursday morning. The larger waves arrive later Thursday
  into early Friday. Waves will diminish through the day 
  Saturday.

* LOCATION...Primarily south facing coastal sections of marin and
  santa cruz counties. In particular southwest facing
  beaches...including but not limited to...stinson beach...santa
  cruz boardwalk beach and twin lakes beach.

* POTENTIAL IMPACTS...Increased risk of drowning or being pulled
  out to sea by this energetic swell train. Never turn your back 
  on the ocean!


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Beach Hazard Statement for rip currents means that conditions
are present to support a heightened risk of strong rip currents.
Rip currents are typically more frequent and stronger in the
vicinity of jetties...inlets...and piers. Swimmers caught in a rip
current should swim parallel to the coast to escape the rip
current before trying to swim for shore. Swimmers should always
swim near a lifeguard.

A Beach Hazard Statement for sneaker waves 
means that conditions are present to support a heightened risk of 
unsuspecting beach goers being swept into the sea by a wave. 
People walking along the beach should never turn their back to the
sea. Fisherman should avoid fishing from rocks or jetties.

A Beach Hazard Statement for longshore currents means that 
conditions are present to support strong currents which parallel 
the coast. Strong longshore currents can quickly carry swimmers 
down shore away from their original point of entry. Longshore 
currents can feed into rip currents which may carry a swimmer 
quickly out to sea. Swimmers caught in a longshore current should 
swim towards shore for safety. In contrast, swimmers caught in a 
rip current should swim parallel to the coast to escape the rip 
current before trying to swim for shore. Always swim near a 
lifeguard.
