## extract

High Surf Advisory — Guam; Rota; Tinian; Saipan
Severity: Minor. Certainty: Likely.
* WHAT...Large breaking waves of 8 to 12 feet and dangerous rip
currents expected in the surf zone.

* WHERE...North and east facing reefs of the Marianas.

* WHEN...Until 4 PM ChST Saturday.

* 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...Long-period east to northeast swell,
emanating from distant Typhoon Dolphin, continues to produce a
high risk of rip currents and hazardous surf along north and
east-facing reefs. As Dolphin continues to move toward Iwo To,
the long-period swell direction is expected to shift north over
the next few days, and then northwest around midweek. As it does
so, a high risk of rip currents and hazardous surf are expected
to develop along west facing reefs later this week.
