High temperatures and hazy air from wildfire smoke are hanging around the Portland metro area on Thursday afternoon.

The air quality could deteriorate in the evening hours into the “unhealthy for sensitive groups” range, the Oregon Dept. of Environmental Quality said.

That means people with health problems, the elderly and young children shouldn't be outside for too long.

DEQ officials said that while it does look hazy in the region, most of the smoke is in the upper altitutes.

The afternoon is usually the worst time of day for air quality, since temperatures are near their peak.

The air should clear back up overnight as temperatures cool.
