Small Craft Advisory
Issued: 7:09 PM Mar. 19, 2026 – National Weather Service
...SMALL CRAFT ADVISORY REMAINS IN EFFECT UNTIL 5 PM CHST THIS AFTERNOON... * WHAT...Seas 8 to 10 feet. * WHERE...Marianas Coastal Waters. * WHEN...Until 5 PM ChST this afternoon. * IMPACTS...Conditions will be hazardous to small craft. * ADDITIONAL DETAILS...Building northeast to east swell, reinforced by diminishing long-period north to northeast swells from distant low pressure systems will continue to produce hazardous seas up to 10 feet over Marianas coastal waters through at least this afternoon. Overall, the long-period swells are gradually subsiding, but the building northeast to east swell will keep seas elevated, potentially remaining at hazardous levels of 8 to 10 feet over eastern coastal waters of Tinian and Saipan through the weekend. Moderate to fresh winds out of the northeast are expected through early next week. PRECAUTIONARY/PREPAREDNESS ACTIONS... Inexperienced mariners, especially those operating smaller vessels, should avoid boating in hazardous conditions. &&
Rip Current Statement
Issued: 6:27 PM Mar. 19, 2026 – National Weather Service
...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST THIS AFTERNOON... ...HIGH RIP CURRENT RISK REMAINS IN EFFECT UNTIL 4 PM CHST THIS AFTERNOON... * WHAT...Large breaking waves of 8 to 10 feet and dangerous rip currents. * WHERE...For the High Surf Advisory, north facing reefs of the Marianas. For the High Rip Current Risk, north and east facing reefs. * WHEN...Until 4 PM ChST this afternoon. * 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...Elevated long-period north to northeast swell, produced by distant mid-latitude frontal systems, will continue to produce hazardous surf along north facing reefs, and a high risk of rip currents along north and east facing reefs through this afternoon. The long-period swells are gradually subsiding and surf is decreasing, however, surf and rip risk will remain at elevated levels over the weekend, possibly hovering just below hazardous levels for north facing reefs. Additionally, minor coastal inundation along northern shorelines still remains possible through this afternoon, especially during times of high tide, although the overall threat has been diminishing. PRECAUTIONARY/PREPAREDNESS ACTIONS... Rip currents will be life threatening. 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. &&
