## 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...For the High Surf Advisory, from 10 PM this evening to
4 PM ChST Saturday. For the High Rip Current Risk, through
Saturday 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...Long-period east to northeast swell,
emanating from distant Typhoon Dolphin, continues to produce a
high risk of rip currents along east-facing reefs, spreading to
north-facing reefs beginning tonight, with hazardous surf also
expected to develop along north and east-facing reefs tonight.
As Dolphin passes the far northern CNMI, 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, is expected to develop along
west facing reefs later this week.
