North and east facing reefs of the Marianas

...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST MONDAY... ...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH MONDAY AFTERNOON... WHAT...Large breaking waves of 9 to 12 feet, up to 14 feet along north facing reefs. Dangerous rip currents. WHERE...North and east facing reefs of the Marianas. WHEN...For the High Surf Advisory, until 4 PM ChST Monday. For the High Rip Current Risk, through Monday 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...Strong winds around a strong low pressure system near Japan and a Kona Low that is northwest of Hawai'i have been producing long-period NNW and NE swells to the region. Hazardous surf and a high risk of rip currents are expected along north and east facing reefs. Surf is expected to build near 15 feet along north facing reefs, which may possibly warrant a High Surf Warning. As NNW swell builds over the coming days, it can potentially build to hazardous levels of 9 feet along west facing reefs, likely needing the advisory to be extended. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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.
