このコンテンツについて
Yesterday, ozone levels exceeded the federal health standard at six monitors around the Phoenix Valley. However, PM10 and PM2.5, which refer to dust and fine particulate pollutants, mostly stayed within the good AQI category, except at a few locations experiencing increased local activity. This morning, elevated levels of dust and smoke were observed at multiple sites, but forecasts predict these should improve as the day progresses and as temperatures rise.
Phoenix is facing the hottest day of the week, with highs near 115 degrees Fahrenheit. After today, cooler air and daily afternoon breezes are expected to arrive, likely improving air quality as the weekend approaches. The incoming weather pattern is expected to bring ozone levels down, possibly into the good category, while PM10 and PM2.5 may remain elevated during morning hours due to local activity before dissipating later in the day.
The overall air quality is satisfactory for most people, and no special precautions are needed for the general public. Sensitive individuals should limit prolonged or heavy exertion outdoors, especially during peak heat and pollution hours. For everyone else, it’s a good day to enjoy typical outdoor activities, while staying hydrated and mindful of the intense heat. The forecast indicates that both air quality and temperatures should improve gradually after today.
