Hello, fall chill: Strong winds buffet Las Vegas, Mount Charleston power cut

The fall chill, with strong winds, is making its mark in the Las Vegas Valley.

The Las Vegas Valley and surrounding areas are under a wind advisory until 5 a.m. Tuesday.

On Monday, winds that gusted up to 45 mph at each of the valley’s three airports and Red Rock National Conservation Area lightened a bit but were still at 27-35 mph Monday evening at the airports, according to the National Weather Service.

“With this type of weather pattern, the gusts are usually strongest in the daylight hours,” meteorologist Chris Outler said. “The cold front is expected to move through the valley between midnight and 2 a.m., dropping the temperatures and shifting the winds to come from the north and northwest.”

Some sprinkles are a possibility Tuesday morning, but only about 20 percent.

“We may see some or nothing,” Outler said.

At 4 p.m., wind gusts had diminished to about 30 mph at the valley’s three airports and around 40 mph at Nellis Air Force Base.

At 8:30 p.m., departing flights were delayed about 15 minutes at Harry Reid International Airport because of the wind, according to a Federal Aviation Administration website. Delays averaged 75 minutes during the noon hour.

NV Energy de-energized lines that serve 466 Mount Charleston area customers shortly before 7:45 p.m. Monday in an effort to reduce the risk of wildfires. Power is expected to be off for residents until 10 a.m. Tuesday, according to an NV Energy spokeswoman.

Valley temperatures will see a high near 70 degrees on Tuesday but Tuesday morning lows will be sub-50 degrees, according to the weather service.
