Air quality improves, but haze and smoke may return early Saturday
Air conditions improved across the valley on Friday but smoke and haze could return Saturday morning, according to the latest National Weather Service forecast.
A Clark County Department of Environment and Sustainability smoke advisory for the Las Vegas Valley issued Thursday was extended through Sunday.
Early Friday, most air monitoring stations were showing moderate air quality. Conditions improved gradually Friday afternoon to mostly good air quality across the valley.
But smoke and haze from the French fire in Kern County, California, could enter the valley before sunrise on Saturday.
“There is another push coming in tonight,” said meteorologist Clay Morgan, noting winds from the south could blow the gray air to the north. “It will probably arrive before sunrise if it makes it this far east. It was headed across Death Valley before sunset.”
The outlook for ozone is moderate through Sunday while smaller particulates are expected to be in the unhealthy for sensitive groups range.
The Friday high reached 95 at McCarran International Airport. The normal this time of year is 103.
People with respiratory issues should limit their outdoor exposure when ozone and particulate matter rises, according to the Environmental Protection Agency.
