## extract

High Surf Advisory — Guam; Rota; Tinian; Saipan
Severity: Minor. Certainty: Likely.
* WHAT...Large breaking waves of 8 to 11 feet and dangerous rip
currents expected.

* WHERE...West facing reefs of the Marianas.

* WHEN...For the High Surf Advisory, until 4 PM ChST Friday. For
the High Rip Current Risk, through Friday 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...A strong monsoon pattern continues to produce
hazardous surf and a high risk of rip currents along west-
facing reefs through at least Friday afternoon. The High Surf
Advisory and High Rip Current Risk may need to 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.
