High Surf Warning issued March 16 at 4:33AM ChST until March 17 at 5:00AM ChST by NWS Tiyan GU
* WHAT...Large breaking waves of 10 to 13 feet, up to 16 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, until 5 AM ChST Tuesday. For
the Coastal Flood Watch and the High Rip Current Risk, through
late tonight.
* 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. 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.
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.
