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

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

AFTERNOON...



* WHAT...Large breaking waves of 8 to 12 feet and dangerous rip 

  currents.



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



* WHEN...Until 4 PM ChST Friday. 



* 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 long-period north to northeast 

  swell, produced by distant mid-latitude frontal 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 Friday afternoon. Swells look to gradually subside, 

  however, there is still a potential for surf and rip risk to 

  remain elevated over the weekend. Although the overall threat of

  coastal inundation has decreased, minor coastal inundation 

  along northern shorelines still remains possible through Friday 

  afternoon, especially during times of high tide. Looking further

  in time, surf is anticipated to remain around the 9 foot level

  for the next several days. Beach goers and Surfers should 

  exercise caution through the first half of next week.



PRECAUTIONARY/PREPAREDNESS ACTIONS...



Rip currents will be life threatening. 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.
