Dead gray whale spotted near Vashon Island

VASHON ISLAND, Wash. -- Authorities are investigating reports of a dead gray whale off Vashon Island.

The Coast Guard said they put out warnings to marine traffic near the northwest side of the island.

Officials with Cascadia Research told Q13 News they do not believe this is the same whale that was spotted earlier this month in Seattle's Ballard Locks. They said the dead whale had been spotted in other areas of Puget Sound.

This is a developing story and will be updated.
