TCEQ Daily Air Quality Forecast Update

Saturday 04/30/2016

Smoke from agricultural burning in Mexico and Central America should continue across parts of South, Central, and Southeast Texas. The smoke will diminish from west to east across Central and parts of South Texas with the passage of a cold front, but the overall daily PM2.5 AQI is forecast to reach “Moderate” or possibly higher levels in the Brownsville-McAllen area and “Moderate” levels in the Corpus Christi, Houston, Laredo, and Victoria areas.

Winds may be light enough and incoming background levels high enough for ozone to reach “Moderate” levels in the Austin, Dallas-Fort Worth, San Antonio, and Waco-Killeen areas; background levels may also be high enough for ozone to reach “Moderate” levels in the El Paso area. Highest ozone concentrations are expected in the afternoon and early evening.

Elsewhere in the state, moderate winds, heavy cloud cover with precipitation, and/or low incoming background levels should help to keep air quality in the “Good” range.
