beach erosion. Rip currents can sweep even the best swimmers away
from shore into deeper water.
Additional Details:
As Sinlaku continues to move away to the
north-northeast, the primary swell has shifted to the north and
decreased, allowing surf to fall below hazardous levels along west
and south facing reefs while remaining hazardous along north
facing reefs overnight. Surf is likely to further decrease along
all reefs the next several days, allowing the rip current risk to
drop as well.
