Air quality advisory
The Clark County Department of Environment and Sustainability advisory continues Friday for elevated levels of smoke and ozone because of regional wildfires.
According to the U.S. Environmental Protection Agency, people who may be most sensitive to elevated levels of particulates and ozone include individuals with respiratory problems, cardiac disease, young children or senior citizens.
Consult your physician if you have a medical condition that makes you sensitive to air quality conditions.
After Labor Day, the triple-digit days might be in the past — thanks to a cold front headed south in the middle of the country.
“We agree that a big cold air mass will come south. The question is how far does it penetrate and how far west does it come,” weather service meteorologist Clay Morgan said. “If it comes more west, the cooldown will be bigger, but the winds will be stronger presenting a fire danger. If it stays further away, it won’t cool down as much and the winds won’t be as strong.”
The current forecast projects a high of 93 on Tuesday and 89 on Wednesday.
Dry streak extended
Thursday was the 136th day without measurable rain at McCarran International Airport. The record is 150 rain-free days in 1959.
The record could be tied Sept. 17.
