* 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, until 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 north and east-facing reefs, along with hazardous surf along said 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.
Guam,Guam
Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.
If caught in a rip current, relax and float. Don't swim against the
current. If able, swim in a direction following the shoreline.
If unable to escape, face the shore and call or wave for help.
