High Surf Advisory issued May 7 at 3:55PM ChST until May 8 at 4:00PM ChST by NWS Tiyan GU
Event:
High Surf Advisory
Urgency:
Expected
Effective:
May 6, 2026 - 10:55pm
Expires:
May 7, 2026 - 1:00pm
Description:
* WHAT...Large breaking waves of 8 to 10 feet in the surf zone
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...For the High Surf Advisory, until 4 PM ChST Friday. For
the High Rip Current Risk, through Sunday 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 trade swell, reinforced by a
trade-wind surge caused by the pressure gradient between
Tropical Storm Hagupit (05W) to the south-southwest and the
subtropical ridge to the north, is producing a high risk of rip
currents along north and east facing reefs, and hazardous surf
along north facing reefs. Although the primary swell component
is easterly, the small northerly swell energy, in addition to
swell wrap-around effects, is sufficient to maintain hazardous
surf of 9 feet along north facing reefs.
Instruction:
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.
