* WHAT...Increased threat of sneaker waves expected.

* WHERE...Coastal Del Norte, Northern Humboldt Coast,
Southwestern Humboldt and Mendocino Coast Counties.

* WHEN...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 sneaker waves can also move large
objects such as logs, crushing anyone caught underneath.

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.
