...BEACH HAZARDS STATEMENT IN EFFECT FROM 1 AM PST SUNDAY MORNING
THROUGH 4 PM PST SUNDAY AFTERNOON...

* WHAT...Moderate to high threat of sneaker waves expected.

* WHERE...Beaches along the southern Oregon Coast, including the
  beaches of Douglas, Coos and Curry Counties

* WHEN...From 1 AM PST Sunday morning through 4 PM PST Sunday
  afternoon.

* IMPACTS...Even during calm conditions, sneaker waves can sweep
  up the beach without warning and knock unsuspecting people over
  and pull them out to sea. Shock and hypothermia can occur
  quickly in the cold Pacific waters. In addition, logs and other
  debris can be lifted and carried by the waves, crushing or
  entrapping unsuspecting victims underneath. 

* ADDITIONAL DETAILS...The sneaker wave threat is even higher 
  considering this will arrive with an incoming high tide Sunday 
  morning. The waves are not especially large, generally in the 
  3-5 foot range with periods of 19-21 seconds, but these waves 
  could have the ability to run farther up the beach than usual, 
  resulting in sneaker waves.

* View the hazard area in detail at 
  https://www.wrh.noaa.gov/mfr/HAZARD

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Use extreme caution along the beaches and keep your distance from
the ocean. NEVER turn your back on the ocean!

Remain out of the water to avoid hazardous swimming conditions.
