 When you think about all the factors that lead to these large-scale fires, you have several things. You have the record heat, you have the wind, and you have the low humidity. And in Death Valley this weekend, we are expecting temperatures to get as high as 129 degrees. That is just a few degrees shy of the hottest temperature ever recorded on Earth, 134 degrees. And across the country in New Jersey, a wildfire in Wharton State Forest has spread to 4,000 acres.
