13 gray whales have washed up in Washington state this year

Another dead gray whale has washed ashore in Western Washington, this time at Everett's Harborview Park.

It was found Sunday, a day after another whale was found stranded near Cape Disappointment, north of Astoria, Oregon.

This brings the total number of dead gray whales to 13 so far this year — 10 more than the same time last year for this area.

The Everett Police Department is working with the Washington State Fish and Wildlife and NOAA to determine the cause of death. The whale's age and gender are still under investigation, Michael Milstein with NOAA said. They will likely perform an necropsy on the whale Monday.

Many of the stranded gray whales have been skinny and shown signs of malnutrition. NOAA said there have now been more than 40 stranded dead gray whales on the West Coast, compared to 25 all of last year.

A portion of Harborview Park remains closed.
