LAS VEGAS >> Gusty dry winds delayed flights at McCarran International Airport in Las Vegas, and prompted wildfire warnings and air quality dust advisories in southern Nevada.

The National Weather Service clocked gusts Thursday at more than 40 mph at the airport, where some arrivals were delayed more than 90 minutes and some departures were an hour or more late. Officials said some flights were held on the ground in other cities due to the weather.

Dry and windy conditions were expected to continue until about 8 p.m. PDT, with a red flag fire warning issued in the Mojave Desert and lower Colorado River valley.

Clark County firefighters cited high winds and summoned additional crews to battle an afternoon house fire in a Silverado Ranch neighborhood southeast of the Las Vegas Strip.
