AFTERNOON...

* WHAT...Large breaking waves of 9 to 12 feet, up to 14 feet 
  along north facing reefs. Dangerous rip currents.

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

* WHEN...For the High Surf Advisory, until 4 PM ChST Monday. For
  the High Rip Current Risk, through Monday afternoon.

* 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...Strong winds around a strong low pressure
  system near Japan and a Kona Low that is northwest of Hawai'i
  have been producing long-period NNW and NE swells to the region.
  Hazardous surf and a high risk of rip currents are expected
  along north and east facing reefs. Surf is expected to build
  near 15 feet along north facing reefs, which may possibly
  warrant a High Surf Warning. As NNW swell builds over the coming
  days, it can potentially build to hazardous levels of 9 feet
  along west facing reefs, likely needing the advisory to be
  extended.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

...HIGH SURF WARNING IN EFFECT UNTIL 5 AM CHST TUESDAY...
...COASTAL FLOOD WATCH IN EFFECT THROUGH LATE MONDAY NIGHT...
...HIGH RIP CURRENT RISK NOW IN EFFECT THROUGH LATE MONDAY
NIGHT...

* WHAT...Large breaking waves of 9 to 12 feet, are expected to build
  up to 16 feet along north facing reefs by as early as Monday
  morning. Dangerous rip currents. For the Coastal Flood Watch, 
  significant coastal flooding is possible.

* WHERE...Guam, Rota, Tinian and Saipan.

* WHEN...For the High Surf Warning, until 5 AM ChST Tuesday. For
  the Coastal Flood Watch, through late Monday night. For the High
  Rip Current Risk, through late Monday night.

* IMPACTS...Some roads may be closed. Low lying property may be 
  inundated. Some shoreline erosion may occur. Breaking waves can 
  sweep people off jetties and docks, and into dangerous 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...Lastest altimetry pass shows elevated sea
  heights for the islands of Pagan northward. Looking further north
  on altimetry, sea heights are showing 16 to 20 feet. This is due to
  strong winds around a vigorous low pressure system near Japan and a
  Kona Low that is northwest of Hawai'i, which have been producing
  long-period NNW and NE swells in the region. Hazardous surf and a
  high risk of rip currents are expected along north and east facing
  reefs. Surf is expected to build to around 16 feet along north
  facing reefs, therefore, a High Surf Warning has been issued. 
  Advisory level surf will continue along east facing reefs. As NNW 
  swell builds over the coming days, it could potentially build to 
  hazardous levels of 9 feet along west facing reefs, likely 
  requiring the advisory to be extended to west facing reefs. The 
  coastal flooding along north facing reefs could reach 1 to 3 feet. 
  Once the seas crest and begin to fall, lesser advisory conditions 
  will still apply.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.

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.

  including homes, businesses, and some critical infrastructure 
  may be inundated. Some shoreline erosion may occur. Breaking 
  waves can sweep people off jetties and docks, and into dangerous
  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...Long period NNW swell from a low pressure
  system near Japan and long-period NE swell from a Kona Low
  northwest of Hawai'i continue to produce hazardous surf and a
  high risk of rip currents along west, north, and east facing
  reefs. The main concern will be north facing reefs, where surf
  can reach up to 16 feet through late tonight. Hazardous surf of
  at least 9 feet along west and north and of at least 12 feet
  along east facing reefs may persist longer, so either an
  extension of the Warning or an extension of as an Advisory will
  likely be needed. Coastal inundation along northern shorelines
  could reach 1 to 3 feet through tonight.

* ADDITIONAL DETAILS...Long period NNW swell from a low pressure
  system near Japan and long-period NE swell from a Kona Low
  northwest of Hawai'i continue to produce hazardous surf and a
  high risk of rip currents along west, north, and east facing
  reefs. The main concern will be north facing reefs, where surf
  can reach up to 15 feet through this afternoon. Hazardous surf
  of at least 9 feet along west and north reefs, and of at least
  12 feet along east facing reefs will continue through at least
  Wednesday afternoon. Surf is expected to first fall below
  hazardous levels along west facing reefs as the westerly
  component of the primary swell energy diminishes. Coastal 
  inundation along northern shorelines of 1 to 3 feet is possible 
  through this afternoon.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Everyone should remain out of the water due to life-threatening

  for the High Surf Warning to expire.

* WHERE...For High Surf Advisory and Coastal flood Watch along
  North reefs and shore and for the High Risk of Rip Currents 
  north and east facing reefs of Guam, Rota, Tinian and Saipan.

* WHEN...Until 4 PM ChST Wednesday.
  
* IMPACTS...A few roads may be closed. Low lying property may be
  inundated. Some shoreline erosion may occur. Breaking waves can
  sweep people off jetties and docks, and into dangerous 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...Long period NNW swell from a low pressure 
  system near Japan and long-period NE swell from a Kona Low 
  northwest of Hawai'i continue to produce hazardous surf and a 
  high risk of rip currents along north and east facing reefs. 
  Hazardous surf of at least 9 feet along north reefs will 
  continue through at least Wednesday afternoon. Surf has already 
  fallen below hazardous levels of 9 feet along west and 12 feet 
  along east facing reefs. Coastal inundation along northern 
  shorelines of 1 to 2 feet is possible through Wednesday 
  afternoon especially during high tide. 

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.
