...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH TUESDAY
AFTERNOON...

* WHAT...Dangerous rip currents expected.

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

* WHEN...From this morning through Tuesday afternoon.

* IMPACTS...Rip currents can sweep even the best swimmers away
  from shore into deeper water.

* ADDITIONAL DETAILS...The trade swell will build as the trade-
  wind surge strengthens near and east of the Marianas. This will
  elevate surf along north and east facing reefs and generate a
  high risk of rip currents along east facing reefs through at 
  least Tuesday afternoon.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

  Thursday. For the High Surf Advisory, until 6 PM ChST Sunday. For
  the Coastal Flood Watch, from Monday morning through Wednesday
  afternoon. For the High Rip Current Risk, through Sunday
  afternoon.

* IMPACTS...Numerous roads may be closed. Low lying property
  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.

* ADDITIONAL DETAILS...Strong to near-gale trade winds, enhanced by
  TY Sinlaku, are producing an east swell near 10 feet and supporting
  hazardous surf and a high risk of rip currents. A TY Sinlaku moves
  towards the Marianas swell and surf are expected to build. This
  will likely generate dangerous surf and increase the risk for
  coastal inundation, especially if TY Sunlaku moves through the
  Marianas around Monday night or Tuesday.

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.

6 PM CHST THURSDAY...
...COASTAL FLOOD WATCH REMAINS IN EFFECT FROM MONDAY MORNING
THROUGH WEDNESDAY AFTERNOON...

* WHAT...For the High Surf Warning, dangerously large breaking
  waves of 12 to 16 feet expected in the surf zone. For the High
  Surf Advisory and High Rip Current Risk, large breaking waves of
  10 to 13 feet and dangerous rip currents. For the Coastal Flood
  Watch, significant coastal flooding of 2 feet or greater
  possible.

* WHERE...North, east and south facing reefs of the Marianas. For
  the Coastal Flood Watch, north, east, and south facing
  shorelines.

* WHEN...For the High Surf Advisory and High Rip Current Risk,
  until 6 PM ChST this evening. For the High Surf Warning, from 6

  Watch, from Monday morning through Wednesday afternoon.

* IMPACTS...Numerous roads may be closed. Low lying property
  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.

* ADDITIONAL DETAILS...Strong to near-gale trade winds, enhanced
  by TY Sinlaku, are producing an east swell near 12 feet and
  supporting hazardous surf and a high risk of rip currents. As TY
  Sinlaku moves towards the Marianas swell and surf are expected
  to rapidly build. This will generate dangerous surf and increase
  the risk for coastal inundation, especially as TY Sinlaku begins
  to move through the Marianas on Tuesday.

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.
