High Surf Advisory
Urgency:
Expected
Effective:
December 21, 2024 - 9:50pm
Expires:
December 22, 2024 - 12:00pm
Description:
* WHAT...For the High Surf Advisory, large breaking waves of 6 to
9 feet along west facing reefs and 8 to 11 feet along north
facing reefs. For the High Rip Current Risk, dangerous rip
currents.
* WHERE...For the High Surf Advisory, west and north facing reefs
of the Marianas. For the High Rip Current Risk, west, north,
and east facing reefs of Marianas.
* WHEN...until 4 PM ChST Monday.
* 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...Long-period north swell arrived early this
morning, primarily creating hazardous surf and dangerous rip
currents along north facing reefs, although refracted waves
contribute to high rip risk along east facing reefs as well.
North swell slowly subsides tonight and Monday, allowing for
surf and rip risk to fall below hazardous levels by Monday.
Strong storms continue to push east off the coast of Japan,
generating north swell to impact the region later this week.
Instruction:
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.
