* WHAT...Large breaking waves of 8 to 11 feet and dangerous rip currents expected.
* WHERE...West facing reefs of the Marianas.
* WHEN...Until 4 AM ChST Friday.
* 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...A strong monsoon pattern continues to produce hazardous surf and a high risk of rip currents along west-facing reefs through late tonight and early Friday morning. The High Surf Advisory and High Rip Current Risk may be extended again, potentially increasing back up to hazardous levels along north-facing reefs, as the monsoon pattern and associated west to northwest swells continue into next week.
