...COASTAL FLOOD ADVISORY IN EFFECT UNTIL 5 AM CHST FRIDAY...

...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 5 PM CHST FRIDAY...



* WHAT...Dangerously large breaking waves of 10 to 14 feet. Minor 

  coastal flooding expected.



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

  Palau and Yap. For the Coastal Flood Advisory, along north facing 

  reefs.

  For the High Surf Advisory, until 5 PM ChST Friday.



* IMPACTS...Flooding of lots, parks, and roads with only isolated

  road closures expected. Dangerous swimming and surfing conditions

  and localized beach erosion.



* ADDITIONAL DETAILS...The southwest monsoon swell and the north 

  swell produced by Typhoon Bavi are producing surf of 10 to 14 feet,

  and minor inundation along north facing reefs of about a foot. As 

  Typhoon Bavi continues to move farther away, the surf is expected 

  to also continue to fall, possibly falling below the 9 foot 

  threshold as early as Friday afternoon.



PRECAUTIONARY/PREPAREDNESS ACTIONS...



Inexperienced swimmers should remain out of the water due to

Corrected to include north facing reefs.



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

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

AFTERNOON...



* WHAT...Large breaking waves up to 12 feet expected in the surf

  zone. Dangerous rip currents.



* WHERE...Along north, south, and west 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...Significant west to southwest swells continue

  to emanate from Super Typhoon Bavi (09W) and its trailing monsoon

  pattern, maintaining hazardous surf and a high risk of rip currents

  along north, south, and west facing reefs. So, the High Surf 

  Advisory and High Rip Current Risk have been extended through 

  Friday afternoon. As Bavi continues to pull away and the leading 

  monsoon surge weakens, swells and associated surf will continue to 

  diminish, potentially falling below hazardous levels by Friday 

  night.



PRECAUTIONARY/PREPAREDNESS ACTIONS...



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. Inexperienced swimmers 

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