Oct. 6 - First regional dust day I've seen so far this time of year. The forecast for today was wind gusts as high as 44 mph in the afternoon. Here in Las Cruces I first saw dust at around 1 pm looking out my west facing window in my office. Hourly PM10 in Deming spiked to 400 µg/m3 at noon. Winds at the Las Cruces airport started to increase around 10 am and gusts in the 30 mph range by 11:30 am. The AQI forecast shows moderate air quality due to elevated PM10 in West Texas and parts of southern Otero and Dona Ana counties.
This isn't a strong dust event and doesn't show up on the various long wave difference products but it does kick off our fall dust events.
