## 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...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 Thursday night. 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.
