.OUTLOOK...The easterly trade swell looks to decrease slightly on
Tuesday, but long-period northeasterly swell is expected to keep the
high risk of rip currents along east-facing reefs through at least
Tuesday afternoon. This will also elevate surf on north-facing reefs,
but rip risk is expected to stay moderate.

* Low Risk of rip currents - Strong currents can still occur near
jetties and reef channels. Always have a flotation device with you
in the water.

Moderate Risk of rip currents - Wave conditions support stronger or
more frequent rip currents. Always have a flotation device with you
in the water.

High Risk of rip currents - Large waves will produce strong rip
currents, especially along narrow reefs and beaches. If caught in a
rip current, swim parallel to the beach rather than against the
current.
