Stormy weather is keeping crews looking for tsunami debris away from a dock that washed ashore on a remote beach on the Washington state coast.

A spokesman for the state Marine Debris Task Force, David Workman, says high winds and tides are making it hard to reach the site on the Olympic Peninsula. He says a team hopes to arrive Thursday.

Workman says there’s no confirmation yet whether the dock is debris from the March 2011 tsunami in Japan. It appears to be similar to a Japanese dock that washed ashore last June at Newport, Ore. It was cut up and removed.

The Coast Guard spotted the latest dock Tuesday on a wilderness beach of the Olympic National Park.
