454 PM ChST Sat Oct 3 2026

...COASTAL FLOOD STATEMENT IN EFFECT THROUGH MONDAY AFTERNOON...
...HIGH SURF ADVISORY NOW IN EFFECT UNTIL 4 PM CHST MONDAY...
...HIGH RIP CURRENT RISK NOW IN EFFECT THROUGH MONDAY AFTERNOON...

* 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
