36 hour Surf Zone Forecast for the Marianas from 600 PM Monday
through 600 AM Wednesday

.TONIGHT THROUGH TUESDAY NIGHT (6 PM TO 6 AM WEDNESDAY)...
Rip current risk.....Moderate *.
Surf Height
      North facing reefs............2 to 4 feet.
      East  facing reefs............3 to 5 feet.
      South facing reefs............2 to 4 feet.
      West  facing reefs............1 to 3 feet.
Swell/Period
      Primary swell................East at 2 to 4 feet.
      Primary period...............8 seconds.
Water temperature
      Ritidian buoy..........86 Degrees.
Maximum afternoon heat index...........Around 99.
Coastal Winds............Northeast at 10 mph shifting to northwest
                         wind on Tuesday.

.OUTLOOK...Some uncertainty exists in the marine forecast due to
Invest 91W. A relaxation in winds during the middle of the week could
lead to a decrease in seas. As 91W moves away from the Marianas,
intensification of the system could lead to a larger fetch of stronger
southerly winds over the Marianas, leading to an increase in seas,
swells, and surf.

* 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.
