Town of Eureka evacuated due to risk from Iron fire as officials forecast more hot weather in week ahead Extreme heat and dry, windy conditions are fueling multiple wildfires across the US west, including a massive blaze in Utah that forced the evacuation of a small town, with hot weather in the forecast raising the risk of more blazes in the week ahead. The Iron fire in Utah’s Juab county was first detected on Saturday and has so far blackened more than 2,000 acres. The fire, about 70 miles (113km) south-west of Salt Lake City, forced the evacuation of Eureka, population 1,000, and people at a nearby ranch.
