A thick layer of smoke has been hanging over Central Texas.
And when you walked outside today you probably saw the thick haze.
The smoke is actually coming from fires in East Texas.
But as of right now, there isn't much to worry about in terms of air quality because we are still considered to be in the moderate level.
"Of course that can change, and of course also because of wind patterns, one area may be fine, but 5 miles away it could be a whole different situation," Chris Evilia with the Metropolitan Planning Organization said.
This means anyone with pre-existing breathing problems should limit their outdoor exposure.
And if you thought we didn't have any effects from hurricane Irene, think again.
Evilia said we have experienced an increase in ozone, which is the main component of smog.
But those pollutants are coming from places like Tennessee and even farther up the Northeast coast.
