LAS VEGAS — Nevada's largest power provider urged customers to conserve electricity Saturday and Sunday evenings because of extreme heat and wildfires affecting transmission lines in western states.
Customers should turn off lights and pool pumps, unplug appliances not in use and avoid using large appliances such as dishwashers from 6-9 p.m. each day, NV Energy said Saturday in a statement. "Conservation is the best way to reduce strain on the local power grid."
The National Weather Service issued an extreme heat warning that runs until 8 p.m. Monday and said Las Vegas could hit its all-time high during the weekend.
The record high for Las Vegas is 117 degrees Fahrenheit at McCarran International Airport, according to the weather service.
The city has recorded that high temperature four times, most recently in June 2017.
The forecast high for Las Vegas was 116 F on Saturday and 115 F on Sunday.
Clark County, which includes Las Vegas and Laughlin, set up 13 cooling stations for people needing a break from the heat.
