Rip Current Statement issued November 26 at 3:47AM ChST until November 27 at 4:00AM ChST by NWS Tiyan GU

Effective: Wed November 26, 2025, 3:47 AM
Expires: Wed November 26, 2025, 6:00 PM

* WHAT...Dangerous rip currents. * WHERE...East facing reefs of the Marianas. * WHEN...Through late tonight. * IMPACTS...Rip currents can sweep even the best swimmers away from shore into deeper water. * ADDITIONAL DETAILS...Elevated easterly trade swell is expected to persist, maintaining a high risk of rip currents along east facing reefs of the Marianas through at least late tonight. Swell and associated surf is expected to diminish through the second half of the week, which may allow the high rip current risk to fall to moderate by Friday.

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
