Event:
High Surf Advisory
Urgency:
Expected
Effective:
October 2, 2026 - 11:54pm
Expires:
October 3, 2026 - 2:00pm
Description:
* WHAT...For the High Surf Advisory, large breaking waves of 9 to 12
feet in the surf zone. For the High Rip Current Risk, dangerous rip
currents. For the Coastal Flood Statement, isolated minor coastal
flooding.
* WHERE...North, south, and west facing reefs of Tinian and Saipan.
* WHEN...Until 4 PM ChST Monday.
* IMPACTS...Some water on low lying roads and property. 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 swells emanating from the
southwesterly monsoon surge and Typhoon Choi-wan (26W) to the north
will allow advisory-level surf and a high risk of rip currents to
continue longer than previously anticipated. The Coastal Flood
Watch has been upgraded to a Coastal Flood Statement as minor
coastal flooding is expected.
Instruction:
Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.
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.
