High Surf Warning

* WHAT...Dangerously large breaking waves of 12 to 16 feet. Isolated minor coastal flooding expected.

* WHERE...North and west facing reefs and shorelines of Yap and Palau.

* WHEN...For the High Surf Warning and Coastal Flood Statement, until 5 AM ChST Thursday. For the High Surf Advisory, from 5 AM Thursday to 5 PM ChST Friday.

* IMPACTS...Some water on low lying roads and property. Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life-threatening swimming conditions and significant beach erosion can be expected.

* ADDITIONAL DETAILS...As Super Typhoon Bavi (09W) passes well north of the region, the trailing monsoon surge gradually shifts northwest. Significant north to northwest swell and southwest swell associated with this pattern will still persist over the next several days, gradually weakening late week. Dangerous surf of up to 16 feet along north and west facing reefs is expected through tonight, capable of producing minor coastal flooding along the respective shorelines. Then surf may fall below dangerous levels of 15 ft Thursday morning, but is still expected to remain hazardous through Friday afternoon.
