36 hour Surf Zone Forecast for the Marianas from 600 PM Friday
through 600 AM Sunday

.TONIGHT THROUGH SATURDAY NIGHT (6 PM FRIDAY TO 6 AM SUNDAY)...
Rip current risk.....Moderate *.
Surf Height
      North facing reefs............5 to 8 feet.
      East  facing reefs............6 to 8 feet.
      South facing reefs............2 to 3 feet.
      West  facing reefs............4 to 6 feet.
Swell/Period
      Primary swell................Northeast at 4 to 6 feet.
      Primary period...............8 to 9 seconds.
      Secondary swell..............Northwest at around 3 feet.
      Secondary period.............11 to 12 seconds.
Maximum afternoon heat index...........Around 98.
Water temperature
      Tanapag buoy..........84 Degrees.
Coastal Winds............East at 10 to 20 mph.

.OUTLOOK...Surf and winds look to increase further starting Sunday,
as multiple pulses of stronger north swell and fragments of a shear
line make their way across the region. This, in turn, may allow
hazardous surf and a high rip current risk to develop along north
facing reefs, and a high rip current risk along east facing reefs
starting Sunday and into early next 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.
