Hazardous air conditions along the southern U.S. border have led health officials to urge residents in parts of Texas and New Mexico to stay indoors and keep windows closed. The Environmental Protection Agency (EPA) issued its highest air quality alert for a 150-mile area centered around El Paso, Texas, where strong winds have stirred up large amounts of dust and smoke. The National Weather Service (NWS) also released a blowing dust advisory for El Paso and nearby Santa Teresa, New Mexico, warning of reduced visibility and potential health risks.

Air quality levels reached an Air Quality Index (AQI) of 290, considered extremely dangerous for everyone. Monitoring services reported high concentrations of PM10 particles—tiny inhalable pollutants from dust, smoke, and debris—that can penetrate deep into the lungs and worsen respiratory and heart conditions. Officials advised people, especially those with breathing problems, to remain indoors and avoid travel during dust storms. Red Flag Warnings and high wind alerts remain in effect across parts of the Southwest, signaling an increased risk of wildfires and rapidly changing weather conditions.
