Strong northwesterly winds are expected to continue through today and into this evening, followed by the potential for ongoing high winds into early next week as a significant temperature change in the Valley is anticipated. These high winds have the potential to cause blowing dust and elevated PM10 concentrations. The District recommends that residents in affected areas remain indoors with window and doors closed, avoiding exposure to blowing dust.
Strong winds often cause localized blowing dust in areas where soils are exceptionally dry—creating unhealthy concentrations of particulate matter 10 microns and smaller (PM10). Exposure to particulate pollution can cause serious health problems, aggravate lung disease, trigger asthma attacks and bronchitis, and increase risk of respiratory infections.
Where conditions warrant, people with heart or lung disease should follow their doctors’ advice for dealing with episodes of particulate exposure. Additionally, older adults and children should avoid prolonged exposure or heavy exertion, depending on their local conditions.
