...high surf warning remains in effect from 9 am this morning to
9 pm pst monday...

* waves and surf...breaking waves rapidly building to around 30 
  feet along the northwest california coast during the latter 
  half of the weekend. the highest surf will be along west and 
  northwest facing beaches. 

* timing...building surf late this morning through this evening 
  with high surf continuing into monday. 

* impacts...large breaking waves along the coast will lead to 
  increased wave run-up on beaches with waves topping and 
  washing over large rocks and jetties. these large waves can be 
  erratic and unpredictable. use extra caution near the surf 
  zone as these large waves will be capable of sweeping people 
  into the frigid and turbulent ocean water. mariners traversing 
  the bar are urged to exercise extreme caution especially 
  during max ebb which is predicted to occur around 900 pm 
  sunday and 1000 am monday, or stay in port until the threat 
  subsides. 

precautionary/preparedness actions...

a high surf warning indicates that dangerous, battering wave will
pound the shoreline. this will result in very dangerous swimming
conditions and deadly rip currents.

  will be likely during times of high tide on monday and tuesday

  beaches, beach parking lots and harbor walkways. 

* impacts...the high surf will continue to bring a threat of 
  strong rip currents and breaking waves that can suddenly 
  overtop rocks and jetties. from late sunday evening through 
  early tuesday morning, there will be more significant and 
  numerous impacts with the very large and damaging surf 
  expected, including frequent and very strong rip currents and 
  sneaker waves, along with a threat of significant beach 
  erosion and possible damage to piers and coastal structures. 
  the very large surf and very strong rip currents will bring 
  extremely dangerous and potentially life-threatening 
  conditions to unexperienced swimmers and surfers, with 
  powerful waves battering rocks and jetties. in addition, large 
  breaking waves can be expected across the morro bay harbor 
  entrance, potentially capsizing small boats. 

* tides...peak high tide on monday will be 5.4 feet around 550 am,
  then 5.7 feet around 620 am tuesday morning.

able, swim in a direction following the shoreline. if unable to
escape, face the shore and call or wave for help.

a coastal flood advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.

...high surf warning remains in effect until 9 pm pst monday...

* waves and surf...a powerful west to northwest swell will 
  create breakers of 25 to 40 feet, with breakers occasionally 
  exceeding 50 feet at favored break points along the coast. 

* timing...energetic waves will build through the day, peaking
  tonight into monday morning. waves will begin to gradually 
  subside late monday night into tuesday. 

* impacts...large breaking waves along the coast will lead to 
  increased wave run-up on beaches with waves topping and 
  washing over large rocks and jetties. these waves can easily 
  move large logs and other beach debris and cause localized 
  beach erosion. localized coastal flooding is also possible.

  will be capable of sweeping people into the frigid and 
  turbulent ocean water. 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 very dangerous due to strong currents and powerful breaking 
  waves.

a high surf warning indicates that dangerous, battering waves are
expected to pound the shoreline, bringing potentially damaging
