...BEACH HAZARDS STATEMENT IN EFFECT FROM THIS EVENING THROUGH
SUNDAY MORNING...

* WHAT...High threat for sneaker waves expected.

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

* WHEN...From 11 PM PDT this evening through 8 AM PDT Sunday 
  morning.

* 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 17-19 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/map/?wfo=mfr

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 and avoid areas of the beach with excess
debris.
