Rip Current Statement issued April 8 at 3:45PM ChST until April 10 at 4:00PM ChST by NWS Tiyan GU

Effective: Wed April 8, 2026, 3:45 PM
Expires: Thu April 9, 2026, 6:00 AM

* WHAT...Dangerous rip currents. * WHERE...East facing reefs of the Marianas. * WHEN...Through Friday afternoon. * IMPACTS...Rip currents can sweep even the best swimmers away from shore into deeper water. * ADDITIONAL DETAILS...Strengthening easterly swell will continue to bring a high risk of rip currents along east facing reefs of the Marianas, now through at least late Friday afternoon. As tropical disturbance Invest 90W passes near the Marianas, swells along the lee side of said system may continue to bring elevated surf along east and potentially south facing reefs during the weekend.

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.
