Officials in Washington state say the number of people missing from last Saturday's massive mudslide is now down to 30.

Snohomish County Emergency officials confirmed another death today and say another body was located but not yet recovered.

It brings the official death toll from the landslide to 18.

Bad weather and contamination from household and industrial chemicals are complicating search and rescue efforts at the sight of the mudslide in the rural area about 50 miles northeast of Seattle.

Hazmat teams were sent to possible contaminated areas to assess whether crews cold safely work around them.
