Health officials have issued urgent air quality warnings along the U.S. southern border as hazardous conditions affect parts of Texas and New Mexico. The Environmental Protection Agency (EPA) raised its highest alert level for a roughly 150-mile stretch, warning that the pollution poses risks to everyone — including healthy individuals. Residents in areas such as El Paso, Texas, and nearby New Mexico communities are being advised to stay indoors, keep windows closed, and limit outdoor activity.

Air Quality Index (AQI) readings climbed near 290, placing conditions in the “very unhealthy” to “hazardous” range. Levels above 200 signal serious health concerns for the entire population. Officials say the spike is primarily due to high concentrations of PM10 — tiny dust and debris particles that can travel deep into the lungs. Exposure may worsen asthma and other respiratory issues and increase heart-related risks over time.

The National Weather Service has also issued blowing dust advisories and high wind warnings. Gusts exceeding 75 miles per hour are reducing visibility and spreading airborne dust. Drivers are urged to use caution and pull off the road safely if visibility drops suddenly. Red Flag Warnings remain in effect in parts of the Southwest, indicating an elevated wildfire risk due to dry, windy conditions.

Public health guidance includes avoiding strenuous outdoor activity, using indoor air purifiers, and wearing protective masks if going outside is necessary. Officials continue monitoring the situation and encourage residents to stay updated through reliable weather and air quality reports.
