...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST SUNDAY...

...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH SUNDAY

AFTERNOON...



* WHAT...Large breaking waves of 7 to 10 feet and dangerous rip 

  currents.



* WHERE...For the High Surf Advisory, north facing reefs of the

  Marianas. For the High Rip Current Risk, north and east facing

  reefs.



* WHEN...For the High Surf Advisory, until 4 PM ChST Sunday. For

  the High Rip Current Risk, through 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...Elevated northeast to east swell, reinforced

  by diminishing long-period north to northeast swell produced by

  distant low pressure systems, will continue to produce hazardous

  surf along north facing reefs, and a high risk of rip currents

  along north and east facing reefs through at least Sunday

  afternoon. Swells, surf, and rip current risk will then briefly

  diminish, increasing once more through Monday as the northeast

  swell is reinforced by a building trade-wind surge. This may lead

  to a reissuance or extension of hazards.



PRECAUTIONARY/PREPAREDNESS ACTIONS...



Rip currents will be life threatening. Inexperienced swimmers

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



Rip currents will be life threatening. 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.
