"It's worse than we see usually," said John Wilson, executive director of the Galveston-Houston Association for Smog Prevention, which issued a news release Monday pointing out that Houston, with two months left in the season, has already eclipsed by one day the number of days last year when the city violated the ozone standard.
So far, Houston has exceeded the standard on 27 days, but that number is likely inflated by a half-dozen new monitors that were installed this year, the TCEQ said.
The plume of ozone was still moving toward the northwest in the late afternoon, and had a chance of reaching Aldine, and triggering level purple, based on an eight-hour average, at a couple of sites, a TCEQ meteorologist said.
"This is not over yet," said Bryan Lambeth, a senior meteorologist for the agency, which was receiving data from 29 monitors Monday. "This blob is moving, and it will likely impact more sites."

Is Houston the only city with air monitors?
the weather channel gives air alerts - where do they get the info? Do we really know the content of the air we breathe. I don't. Shouldn't we?
