Heavy smoke from range fires in Southwest Texas impacted air quality in parts of Southwest, South, and Central Texas on Wednesday April 27th. Smoke from agricultural burning in Mexico and Central America also continued mainly along the coast in the morning in South and Southeast Texas. The highest measured PM2.5 daily averages was 50.0 micrograms per cubic meter (µg/m3) at Eagle Pass CAMS 319, which rated as Level Orange, Unhealthy for Sensitive Groups, on the U.S. Environmental Protection Agency (EPA) Air Quality Index (AQI) scale. PM2.5 in the "Moderate" range on the AQI was measured at all of the monitoring sites in South Texas and at one site in San Antonio and two in Houston. High PM2.5 levels in the "Unhealthy for Sensitive Groups" range or possibly higher are likely to occurred locally in the smoke plumes in Southwest Texas.
