Residents of Arizona, California, and Nevada might start thinking about investing in some sunscreen–and possibly fixing that broken air conditioner–as a massive heat wave is set to sweep through the area. According to weather.com, forecasters have predicted record setting temperatures for much of the region starting this Friday and continuing into the weekend, perhaps going as high as 130 degrees Fahrenheit.

On the high end of the scale is Death Valley in California, which will of course see some of the worst conditions during the heat wave. Experts predict that the desert could see its highest temperatures since 1913 at over 130 degrees. Tourist meccas Las Vegas, Nevada and Phoenix, Arizona will follow closely with the temperatures soaring above 120 degrees.

Visitors on the Strip are advised to resign themselves to their air-conditioned suites and the cool floors of the casinos as the heat wave rolls through. However, it is not urban areas that experts are worried about. Officials are concerned for people living in remote areas and near deserts. Those who plan on doing outdoor activities are advised to check their local weather. In addition, Border Patrol agents are stepping up efforts to rescue migrants attempting to cross the border in these high temperatures, and have already reported an increasing number of deaths. The risk of brush fire is also raised due to dry, low-humidity winds along the California coast.

Although not suffering the same record high temperatures, forecasters say the heat wave may cross over to Colorado and even Utah.

“It’s a potentially historical event that we’re looking at here, and the heat is encompassing all of Nevada, all of Utah and Arizona,” Meteorologist Brian Brong told USA Today.

In comparison, the East Coast will be seeing a soggy weekend punctuated by flooding and thunderstorms.
