* WHAT...For the High Surf Advisory, large breaking waves of 10 to 14 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents. * WHERE...South and west facing reefs of the Marianas. * WHEN...Until 4 PM ChST Monday. * 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...Surf will remain hazardous longer than previously anticipated, so the High Surf Advisory and High Rip Current Risk were extended until Monday afternoon. As Typhoon Champi continues moving away from the region, the dominant southwesterly swell will bring hazardous surf and dangerous rip currents to south and west facing reefs. 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.
