Local air-pollution officials are advising people in the Valley to be careful because gusty winds are expected in the area through Wednesday evening.
The San Joaquin Valley Air Pollution Control District says winds may produce areas of localized blowing dust in the following counties: San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare and the Valley air basin portion of Kern.
Blowing dust can result in unhealthy concentrations of particulate matter. Exposure to particle pollution can cause serious health problems, aggravate lung disease, trigger asthma attacks and acute bronchitis, and increase risk of respiratory infections.
The Valley Air District says adults and children should avoid being outdoors for a long period of time.
