.DISCUSSION...A low risk of rip currents is expected along all
reefs for most of the week. Surf and rip risk could rise late
week or next weekend along north and especially west facing reefs
as a west-northwest swell emanating from a distant tropical
disturbance to our northwest arrives. A moderate risk of lighting
is possible for most the week.

* 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.
