Watches & Warnings

High Surf Warning
Issued: 8:57 AM PST Jan. 17, 2019 – National Weather Service
... High surf warning remains in effect until 5 PM PST Friday... 
... Coastal flood advisory allowed to expire at 9 am PST this 
morning... 


* waves and surf... breaking waves rapidly building to 25 to 35  
feet, with favored locations occasionally exceeding 45 feet.

* Timing... energetic waves will continue to build this morning, 
  peaking during the day before gradually subsiding on Friday. 

* 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. They can easily move 
  large logs and other beach debris and cause localized beach 
  erosion. Use extreme caution near the surf zone as these large 
  waves 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. 


Precautionary/preparedness actions... 

A high surf warning indicates that dangerous, battering waves are
expected to pound the shoreline, bringing potentially damaging
and life-threatening conditions. It is advised that people remain
away from the shoreline during this event, especially staying off
rocks, jetties and beaches.
