* WHERE...North facing reefs of the Marianas.
* WHEN...Until 4 AM ChST Tuesday.
* 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, long-period, north-northwest swell from Typhoon In-fa will continue to produce hazardous surf and a high risk of rip currents along north facing reefs through tonight, likely diminishing below hazardous levels by late tonight as swells steadily diminish. Hazardous surf of 7 to 9 feet early tonight is expected to diminish below hazardous levels, becoming 6 to 8 feet by late tonight.
Instructions
Rip currents will be life threatening. 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.
