What

Increased threat of sneaker waves expected.

Where

The Lost Coast and the Mendocino Coast.

When

Through Wednesday afternoon.

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.

What to Do

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.


Areas Impacted

  • Southwestern Humboldt
  • Coastal Mendocino

Tips to Stay Safe

Your area may see dangerous swimming conditions. Use caution: 

  • Stay off of rocks and jetties due to dangerous conditions
  • Stay out of the water to avoid hazardous swimming conditions, and stay near occupied lifeguard towers 
  • Keep small children in sight and within arm’s reach at all times.
