Haze from wildfire smoke reaches Eugene, Portland and Seattle

    EUGENE, Ore. - The haze over the southern Willamette Valley is wildfire smoke from fires burning in Southern Oregon and Northern California.

    Wildfire smoke has also reached the Portland and Seattle metro areas.

    The good news: the smoke is staying well above ground level.

    "While many will see haze and/or smoke in the sky today," the National Weather Service in Portland said Monday, "latest runs of the HRRR-smoke model suggest most of the smoke will remain aloft, especially north of Eugene."

    Satellite images from Saturday and Sunday afternoons show the shift in the smoke over Oregon.

    On Saturday, the smoke hung over the southern third of the state.

    The EPA doesn't forecast air quality to degrade beyond a Moderate level in the Willamette Valley on Monday.

    And forecasts call for the haze to clear Tuesday afternoon.
