For the second High Surf Advisory and High Rip Current Risk, large breaking waves of 10 to 14 feet in the surf zone and dangerous rip currents expected. * WHERE...North facing reefs of the Marianas. * WHEN...For the first High Surf Advisory and High Rip Current Risk, until 6 AM Tuesday. For the second High Surf Advisory and High Rip Current Risk, from early Thursday morning to Sunday afternoon. * 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...The re-descent of a newly-energized shearline induced by a strong high moving in from the Yellow Sea across the northern Pacific will bring an exceptional north swell, introducing hazardous surf to north facing reefs of the Marianas. Surf may occasionally reach dangerous levels by Saturday, and as such, a High Surf Warning may be considered if conditions warrant. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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. && $$ Pavliukoit
