...HIGH SURF WARNING NOW IN EFFECT UNTIL 4 PM CHST THIS AFTERNOON
ALONG WEST, NORTH, AND EAST FACING REEFS...
...COASTAL FLOOD WATCH NOW IN EFFECT THROUGH THIS AFTERNOON ALONG
NORTHERN SHORELINES...
...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH WEDNESDAY
AFTERNOON ALONG WEST, NORTH, AND EAST FACING REEFS...
...HIGH SURF ADVISORY NOW IN EFFECT FROM 4 PM THIS AFTERNOON TO 4
PM CHST WEDNESDAY ALONG WEST, NORTH, AND EAST FACING REEFS...

* WHAT...Large breaking waves of 10 to 13 feet, up to 15 feet
  along north facing reefs. Dangerous rip currents. Possible
  coastal inundation along northern shorelines.

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

* WHEN...For the High Surf Warning and Coastal Flood Watch, until
  4 PM ChST this afternoon. For the High Surf Advisory, from 4 PM
  this afternoon to 4 PM ChST Wednesday. For the High Rip Current
  Risk, through Wednesday afternoon.

* 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...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
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.
