...HIGH SURF ADVISORY IN EFFECT FROM 6 PM FRIDAY TO 6 AM MONDAY... 
...HIGH RISK OF RIP CURRENTS FROM FRIDAY EVENING THROUGH LATE SUNDAY 
NIGHT...

* WHAT...Large breaking waves of 10 to 13 feet expected in the surf
  zone, along with dangerous rip currents.

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

* WHEN...From 6 PM Friday to 6 AM Monday.

* 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 significant northerly swell generated by a
  distant low pressure system off the coast of Japan, expected to 
  bring hazardous surf to north facing reefs of the Marianas. 
  Nomogram analysis indicates that there is potential for dangerous 
  surf of 15 feet and above starting Saturday, so a High Surf Warning
  may be issued if conditions warrant.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Swim near a lifeguard. 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.

...COASTAL FLOOD STATEMENT REMAINS IN EFFECT FROM 7 AM THIS MORNING 
THROUGH MONDAY AFTERNOON...

* WHAT...For the High Surf Advisory, large breaking waves of 9 to 14
  feet in the surf zone. For the High Rip Current Risk, dangerous rip
  currents. For the Coastal Flood Statement, isolated minor coastal 
  flooding expected.

* WHERE...North and east facing reefs of the Marianas.

* WHEN...For the High Surf Advisory and High Rip Current Risk, until
  4 PM Monday. For the Coastal Flood Statement, from 7 AM this 
  morning through Monday afternoon.

* IMPACTS...Some water on low lying roads and property. 
  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 significant northerly swell generated by a
  distant low pressure system off the coast of Japan is expected to
  bring hazardous surf to north facing reefs of the Marianas. A
  nomogram analysis from a scatterometry pass during the onset of the
  northerly swell off the east coast of Japan a few cycles ago, in
  addition to recent model guidance trends, indicate that there is
  still potential for dangerous surf of 15 feet and above tonight or
  Sunday along north and/or east facing reefs. If conditions warrant,
  a High Surf Warning may be issued this afternoon. Due to already
  high tides, minor coastal inundation of up to 1 foot is possible
  Sunday through Monday afternoon along north shores.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Do not drive through flooded roadways.

Inexperienced swimmers should remain out of the water due to dangerous
surf conditions.

Swim near a lifeguard. 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

  minor coastal flooding. 

* WHERE...For the High Surf Warning and Coastal Flood Statement,
  north facing reefs of the Marianas. For the High Risk of rip
  Currents, along north and east facing reefs. Hazardous surf will

  seas. Life-threatening swimming conditions and significant beach 
  erosion can be expected. Rip currents can sweep even the best 
  swimmers away from shore into deeper water.

* ADDITIONAL DETAILS...Seas and surf are gradually decreasing,
  allowing surf to fall below dangerous levels along east facing
  reefs. However, hazardous surf of 10 to 13 feet and dangerous rip
  currents will continue along east facing reefs. As the surf
  continues to subside, the High Surf Warning could be downgraded to

...HIGH SURF WARNING IS CANCELLED...
...COASTAL FLOOD STATEMENT IS CANCELLED...

* WHAT...Large breaking waves of 9 to 12 feet, and dangerous rip
  currents.

* WHERE...North and east facing reefs of the Marianas.

* WHEN...Until 6 AM 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...Various northerly swells and localized wind
  waves have diminished enough to allow surf to fall below dangerous
  levels. Even so, surf is expected to remain hazardous along north 
  and east facing reefs through at least late tonight or early 
  Tuesday morning. Due to a significant drop in surf, coastal 
  inundation is no longer a threat along northern shores.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Swim near a lifeguard. If caught in a rip current, relax and float. 
Don't swim against the current. If able, swim in a direction

  allowing the surf to fall below hazardous levels along east facing
  reefs. Surf is expected to fall below hazardous levels on north
  facing reefs Tuesday morning. Seas look to remain high enough to
  maintain a High Risk of Rip Currents through Tuesday night.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

...HIGH SURF ADVISORY NOW IN EFFECT UNTIL 5 PM CHST THIS
AFTERNOON...
...HIGH RISK OF RIP CURRENTS THROUGH LATE TONIGHT...

* WHAT...Large breaking waves of 7 to 9 feet, and dangerous rip 
  currents.

* WHERE...For the High Surf Advisory, north facing reefs of the 
  Marianas; for the High Risk of Rip Currents, north and east 
  facing reefs of the Marianas.

* WHEN...For the High Surf Advisory, until 5 PM ChST this
  afternoon. For the High Rip Current Risk, through 5 PM CHST for
  north facing reefs, through late tonight for east facing reefs.

* 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...Seas and surf continue to slowly subside, 
  allowing the surf to fall below hazardous levels along east 
  facing reefs. Surf is expected to fall below hazardous levels 
  on north facing reefs Tuesday morning. Seas look to remain 
  high enough to maintain a High Risk of Rip Currents through 
  Tuesday night.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Swim near a lifeguard. 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.
