PORTLAND, Ore. — An odor has been reported across the Portland metro Tuesday morning, but its source is unknown, officials said.
Cowlitz County officials are reporting this odor all way down I-5 from South Kelso to Vancouver. KGW has received calls and emails in our newsroom from viewers in the Portland area about the smell as well.
The odor has been described as "sulfur-like."
However, Cowlitz County officials have said their monitors are not showing any readings for gas or other substances. Officials have checked pipelines and industrial facilities in the area, who have all said there's been no operational issues.
"It is suggested, if concerned, to stay indoors, windows and doors closed," officials said. "At this time, we do not know the source."
This is a developing story and will be updated with more details as they emerge.
