Urgency:
Expected
Effective:
October 3, 2026 - 10:59am
Expires:
October 4, 2026 - 1:00am
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. A
Coastal Flood Statement remains in effect 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.
