currents expected.

* WHERE...West facing reefs of the Marianas.

* WHEN...Until 4 PM ChST Thursday.

* 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...A strong monsoon pattern continues to produce
hazardous surf and a high risk of rip currents along west-facing
reefs through Thursday afternoon. The High Surf Advisory and High
Rip Current Risk may be extended again, potentially increasing back
up to hazardous levels along north-facing reefs, as the monsoon
pattern and associated west to northwest swells continue into next
week.

Information:

Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.

Rip currents will be life threatening. 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.
