...BEACH HAZARDS STATEMENT IN EFFECT FROM SUNDAY MORNING THROUGH
SUNDAY AFTERNOON...

The National Weather Service in Medford has issued a Beach
Hazards Statement for Sneaker Waves...which is in effect from 
Sunday morning through Sunday afternoon. 

* Hazards...Incoming long period west swell will produce the
  potential for dangerous sneaker waves.

* Timing...The threat of sneaker waves will be elevated Sunday
  morning through Sunday afternoon...especially in the late
  morning and early afternoon.

* Locations Include...All beaches in Curry, Coos, and Douglas
  Counties.

  beach, sweeping people off their feet and into the ocean. They
  can also toss large logs and debris which may injure or crush
  people. Use extra caution. Never turn your back to the ocean,
  and stay off of jetties and exposed structures.

create life-threatening conditions in the surf zone. Caution
should be used when in or near the water.
