Not only is the smoke from Mexico and Central America, but it's also from Pioneer Woman's ranch in Oklahoma and from wildfires in North Texas. TCEQ updated today's information to read:
Friday 4/10/09 Smoke from agricultural burning in Mexico and Central America should continue, and this may raise fine particulate to "Moderate" levels in south and southeast Texas. Residual smoke from wild fires in north central Texas could cause fine particulate to reach "Moderate" levels in parts of central and east Texas. Ozone may reach "Moderate" levels or higher in the Houston area today if a cold front slows down and doesn't move through the area this morning. Elsewhere, moderate winds and low background levels should help to keep air quality in the "Good" range over most of the state.
