944 PM ChST Fri Aug 21 2026

...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH SUNDAY AFTERNOON...

* WHAT...Dangerous rip currents expected.

* WHERE...East facing reefs of the Marianas.

* WHEN...Through Sunday afternoon.

* IMPACTS...Rip currents can sweep even the best swimmers away from
  shore into deeper water.

* ADDITIONAL DETAILS...An east to northeast swell associated with
  Tropical Storm Saudel will bring an increase in surf and produce a
  high risk of rip currents along the east-facing reefs of Guam and
  Rota through at least Sunday afternoon. As Saudel moves closer to
  the far northern Marianas, surf builds along north- facing reefs,
  potentially becoming hazardous later this weekend.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rip currents will be life threatening. 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.
