...HIGH SURF ADVISORY IN EFFECT FROM EARLY THURSDAY MORNING TO SUNDAY
AFTERNOON... 

...HIGH RISK OF RIP CURRENTS FROM EARLY THURSDAY MORNING TO SUNDAY 
AFTERNOON... 

* WHAT...For the first High Surf Advisory and High Rip Current Risk,
  hazardous surf of 7 to 9 feet in the surf zone and dangerous rip
  currents expected. For the second High Surf Advisory and High Rip
  Current Risk, large breaking waves of 10 to 14 feet in the surf zone
  and dangerous rip currents expected.

* WHERE...North facing reefs of the Marianas.

* WHEN...For the first High Surf Advisory and High Rip Current Risk,

  Current Risk, from early Thursday morning to Sunday afternoon.

* IMPACTS...Dangerous swimming and surfing conditions and localized 
  beach erosion. Rip currents can sweep even the best swimmers away 
  from shore into deeper water.

* ADDITIONAL DETAILS...The re-descent of a newly-energized shearline
  induced by a strong high moving in from the Yellow Sea across the
  northern Pacific will bring an exceptional north swell, introducing
  hazardous surf to north facing reefs of the Marianas. Surf may
  occasionally reach dangerous levels by Saturday, and as such, a
  High Surf Warning may be considered if conditions warrant.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to dangerous
surf conditions.

If caught in a rip current, relax and float. Don't swim against the 
current. If able, swim in a direction following the shoreline. If 
unable to escape, face the shore and call or wave for help.
