Due to increasing wind speeds and blowing dust arriving from the southwest, a dust advisory was issued Wednesday.
As part of the county's dust-control program, air quality officials have sent out a notice to construction sites in the Las Vegas valley and other outlying areas in Clark County, asking them to take precautions to prevent blowing dust.
Air Quality officials will continue to monitor conditions and will post an alert on the forecast page if unhealthy levels actually occur.
Excessive dust in the air can aggravate respiratory diseases such as bronchitis and asthma. It may be best for children, the elderly and people with respiratory problems to remain indoors when it is excessively dusty outside.
Windy conditions persisted throughout much of Wednesday, keeping temperatures near average.
