* WHAT…Large breaking waves of 7 to 9 feet and dangerous rip
currents expected in the surf zone.
* WHERE…For the High Surf Advisory, north-facing reefs of the
Marianas. For the High Rip Risk, north and east-facing reefs.
* WHEN…From 6 AM Wednesday to 6 AM ChST Friday.
* 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…A shear line is stalled just north of Saipan
while a pulse of northerly swell moves through the region. This
increase in north swell, combined with the northeasterly trade
swell, will generate hazardous surf for north facing reefs and a
high risk of rip currents for north and east facing reefs come
Wednesday morning. Another significant pulse of north swell is
expected to arrive Thursday, which will maintain these surf hazards
into at least Friday morning.
