AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

Forecast Discussion: The influence of the high pressure over the region will weaken today as atmospheric waves from the Pacific begin to press against it and push it eastward. Though temperatures are expected to remain near or above 100°F today and tomorrow, winds will be breezy both afternoons. The main concern is that winds are expected to assume a westerly direction later this evening (shifting from southwesterly) and be westerly tomorrow as well. Since it has been two weeks since the region's last rain, this will result in a potential for blowing dust in the Yuma area. By Friday, winds calm down and the dust threat diminishes. Ozone still remains the trickiest part of the forecast. There may be a potential for transport of ozone into the area today, but wind strength could help spread out the ozone and limit higher concentrations. Ozone is forecast to decrease tomorrow but is expected to trend upwards toward the weekend due to either more transport or stronger stagnation. We'll continue to watch ozone trends. Check back tomorrow for more. Until then, have a good day! –M. Graves Last Update: Wednesday, May 24, 2017, 8:50 AM
