Gusty winds and blowing dust in the San Joaquin Valley have prompted local air officials to issue a health cautionary statement through Saturday.
The health caution is in effect for Merced, Madera, Fresno, Kings, Tulare, and Kern counties.
Blowing dust can result in unhealthy concentrations of particulate matter 10 microns and smaller, or PM10.
Exposure to particle pollution can cause serious health problems, aggravate lung disease, cause asthma attacks and acute bronchitis and increase risk of respiratory infections, officials said. People with heart or lung diseases should follow their doctors' advice for dealing with episodes of unhealthy air quality.
