With northeast winds buffeting the Las Vegas Valley today, Clark County officials have issued an air-quality advisory for blowing dust, especially in eastern parts of the county.
The Clark County Department of Air Quality, in a news release, said unhealthy levels of dust were not yet occurring. But as part of the county's dust-control program, the department was notifying construction sites in the Las Vegas Valley and other outlying areas and asking them to take precautions to prevent blowing dust.
Airborne dust is a form of inhalable air pollution called particulate matter, which aggravates respiratory diseases such as bronchitis and asthma. It may be best for children, the elderly, and people with respiratory diseases to stay indoors during dust storms.
The National Weather Service’s forecast for today calls for northeast winds around 15 mph with gusts up to 23 mph. Tonight, the winds will shift to the north with gusts as high as 24 mph, forecasters said.
By Friday, forecasters expect only light and variable wind for the Las Vegas Valley.
