A desert area near Martinez Lake in Arizona hit 43°C (110°F), setting a new record for the hottest March temperature ever recorded in the US. The previous record of 42°C (108°F), set in Texas in 1964, had stood for over 60 years. The extreme heat was part of a late-winter heatwave affecting much of the US Southwest, with unusually high temperatures also recorded in California, Arizona and Nevada. #US #arizona #temperature #hot #weather
