...BEACH HAZARDS STATEMENT IN EFFECT FROM 11 AM THIS MORNING 
THROUGH LATE TONIGHT...

* WHAT...Westerly swell of 4 to 6 feet at 17 to 20 seconds will 
  bring an increased risk of sneaker waves to area beaches.

* WHERE...Coastal Del Norte, Humboldt, and Mendocino counties.

* WHEN...From 11 AM this morning through late tonight.

* IMPACTS...Large, unexpected waves can sweep across the beach 
  without warning, sweeping people into the sea from rocks, 
  jetties, and beaches. These waves can also move large objects 
  such as logs, crushing anyone caught underneath.

* ADDITIONAL DETAILS...Long lulls are typical between hazardous
  sneakers waves, and the ocean may appear relatively calm for up
  to 30 minutes between larger wave sets.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Don't be fooled by an ocean that looks calm. There can be 30 
minutes of small waves before a sneaker wave strikes. Avoid rocks 
and jetties. Avoid steep beaches. Stay much farther back from the 
water and never turn your back on the ocean.
