Temperatures continue to rise in the West, as the U.S. battles a prolonged heatwave. Cities across the region are reporting record-high temperatures.

The heatwave is raising fears of a wildfire season, with dryness growing alongside the heat. Wildfires are expected to come anytime between May and October but are now in danger of happening until December after last year’s wildfires began in winter month.

On Sunday, heat alerts were sent across western states, affecting 30 million people.

The heat has surged in places like Death Valley, California, which is prone to wildfires. On Friday, temperatures reached 130 degrees Fahrenheit.

Las Vegas on Saturday saw temperatures reach 117 degrees, joining other parts in the West that have seen temperatures that were 10-to-20 degrees above average.

Las Vegas typically expects high temperatures during the summer, but this heat flash can beat records if temperatures don't subside.

The highest recorded temperature on Earth was recorded in Death Valley, when it hit 134 degrees in 1913.

Death Valley will continue to gain attention if it sees temperatures hit 130 again for the second time in three days.

Western states affected by the heatwave, which has crept over from June, include Oregon, Washington, Colorado, Nevada, Utah, and New Mexico.

The western region can expect these dangerously high temperatures through the first half of this week.
