Central Texas is under an Ozone Watch today and tomorrow.
Watches are usually issued during the summer months when the temperatures are higher and humidity is lower. And so far this year the area is already dangerously close to exceeding EPA standards. Austin sits at a 74 parts-per-billion average for ozone. If that average jumps to 75 PPB, the area will be in non-compliance.
“If we get one day at one site in particular, like our Northwest Austin site which has a 79 parts-per-billion eight-hour average … one more at that level will throw us into non-compliance," says Bryan Lambeth, senior meteorologist at Texas Commission on Environmental Quality.
Deana Altenhoff, Executive Director of the CLEAN AIR Force of Central Texas, agrees. "Ozone season ends October 31st," Altenhoff says. "This is our most critical time of the year because historically this is when we see our highest levels of ozone."
