STOCKTON - High winds may kick up dust throughout the San Joaquin Valley today, potentially causing serious health problems, the San Joaquin Valley Air Pollution Control District said Thursday.

Dust can aggravate lung disease, cause asthma attacks and acute bronchitis, as well as increase the risk of respiratory infections.

A dry cold front moving in from the north was expected to bring moderately strong to gusty winds through the day. That will stir the soil long dried out from the hot summer sun.

Older adults and children should avoid prolonged exposure to the dust, including strenuous activities, and air pollution, officials said. Those with heart or lung ailments might wish to consult a doctor.
