High Surf Advisory issued March 14 at 3:25PM ChST until March 16 at 4:00PM ChST by NWS Tiyan GU

Effective: Fri March 14, 2025, 3:25 PM
Expires: Sat March 15, 2025, 5:30 AM

* WHAT...Large breaking waves of 9 to 14 feet and dangerous rip currents. * WHERE...North and east facing reefs of the Marianas. * WHEN...Until 4 PM ChST Sunday. * 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 significant northeast well is generating hazardous surf and a high risk of rip currents along north and east facing reefs. Surf will likely fall below hazardous levels of 12 feet for east facing reefs around Saturday night, but will continue to meet hazardous criteria of 9 feet for north facing reefs through at least Sunday afternoon. The swell energy is expected to gradually diminish over the next few days, allowing the high risk of rip currents to decrease to moderate Sunday afternoon as well.

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.
