High Surf Advisory issued February 23 at 3:51AM ChST until February 24 at 5:00AM ChST by NWS Tiyan GU

* WHAT…For the High Surf Advisory, large breaking waves of 7 to
10 feet in the surf zone. For the High Rip Current Risk, dangerous
rip currents.

* WHERE…North facing reefs of the Marianas.

* WHEN…For the High Surf Advisory, until 5 AM ChST Monday. For
the High Rip Current Risk, through late tonight.

* 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 weakening northerly swell will allow surf
conditions to fall below hazardous levels, and rip current risk to
drop to moderate along north facing reefs by late Sunday night. At
the same time, trade swell is expected to increase, so the rip
current risk is likely to become high along east facing reefs
during this time.
