Weekend weather: According to the National Weather Service, a rare heatwave event is forecast this weekend



The National Weather Service forecasts a peak of 126 in Death Valley, California. Phoenix, Arizona, expects a high of 117 on Sunday, and Las Vegas, Nevada, is preparing for weekend highs of 113.

The National Weather Service uses different criteria for heat warnings in different parts of the country. A warning of excessive heat indicates unusually high temperatures that can pose significant health risks.

In the southwest, “we take advantage of the so-called heat risk,” said Marvin Percha, a meteorologist with the National Weather Service. This differs from other regions of the country where heat indices play a greater role in heat warnings.

“We look at how rare the event is and compare what is normal,”

; said Percha. “Given the temperatures that we have now forecast, we are looking at a fairly rare event.”

The heat in Phoenix this weekend could break daily records. The expected Phoenix high of 117 on Sunday would exceed the July 12, 115 daily record of 2009. The heat in California and Nevada will be close to the records, but will not quite reach them.

High heat is seasonally appropriate for the region, but usually not as high as long.

Friday marks the 107th anniversary of the hottest day ever recorded on Earth when Death Valley hit 134 degrees Fahrenheit, said CNN meteorologist Pedram Javaheri.

Such high temperatures can be intensified in valleys and on the ground, where materials can start to melt.

While monthly records may not be broken this weekend, excessive heat is part of the general trend of rising temperatures. High heat patterns are just one of many extreme weather events that are exacerbated by climate change.

High temperatures can be dangerous and people in affected areas are asked to take safety precautions. “Everyone with heart or diabetes problems should be extra careful and do their best to really stay away from it,” said Percha.

According to the Centers for Disease Control, more than 600 people die each year from heat-related diseases. Stay safe by staying indoors, staying hydrated, wearing light clothes, and knowing the symptoms of the heat sickness.

“If you need to be outside, try to limit your exposure and keep yourself well hydrated,” Percha said. “Look for air-conditioned cooling centers if you have to.”

Phoenix has a map of the public cooling centers. Check with the local authorities for the nearest cooling center or water dispenser.
