* 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...Until 4 PM ChST Sunday.
* 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.
