The extreme heat is affecting the Valley's prime event and tourism season, with temperatures expected to reach 105 degrees. This has led to changes to events such as the Ostrich festival, Spring Training, and the East Valley's annual carnival, which moved to Rawhide Western Town, providing additional shaded areas, misting zones, indoor cool-down spaces and complimentary water for its second weekend. The National Weather Service has issued an extreme heat warning for the first time in March, but it is expected to remain above-normal temperatures for the foreseeable future. If weather conditions worsen, April's signature events could be disrupted.
