...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 4 PM CHST TUESDAY...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH TUESDAY
AFTERNOON...

* WHAT...Large breaking waves between 8 to 11 feet and dangerous
  rip currents.

* WHERE...North facing reefs of the Marianas. For the High Rip
  Current Risk, north and east facing reefs.

* WHEN...Until 4 PM ChST Tuesday.

* IMPACTS...Dangerous swimming and surfing conditions and
  localized beach erosion. Rip currents can sweep even the best
  swimmers away from shore into deeper water.

* ADDITIONAL DETAILS...Long-period northerly swell continues to
  move through the Marianas, producing hazardous surf and
  dangerous rip currents along north-facing reefs through Tuesday
  afternoon. A broad, disorganized tropical disturbance southwest
  of the Marianas and a shear line across the CNMI is leading to
  an increase in north to northeast swell, which is bringing a
  high risk of rip currents to east facing reefs as well.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.
If caught in a rip current, relax and float. Don`t swim against
the current. If able, swim in a direction following the
shoreline. If unable to escape, face the shore and call or wave
for help.
