"Record-breaking Heatwave Grips Southwest U.S., Taking a Toll on Mind and Body"

The US southwest is experiencing a record-breaking heatwave, with temperatures exceeding 100F (38C) in Arizona, Nevada, New Mexico, and southern California. Phoenix is facing its longest-ever heatwave, with temperatures expected to continue for the next week. The region has not yet seen any monsoon activity, exacerbating the scorching temperatures. Local authorities have closed hiking trails and advised residents to stay cool, hydrate, and check on vulnerable individuals. Cooling centers and hydration stations have been set up to provide relief for those without shelter. The heatwave is attributed to high pressure systems and the lack of precipitation in the area.
