PHOENIX—Heavy snow shut down parts of major interstates in northern Arizona on Thursday while low-lying clouds delayed dozens of flights in Phoenix, after storms earlier this week battered California and left a muddy mess.
The mountainous region of northern Arizona recorded 2 feet (61 centimeters) of snowfall or more in some locations with more expected into the weekend. Snow, ice, and whiteout conditions forced partial closures of Interstates 40 and 17 in and around Flagstaff, northern Arizona’s largest city. I-17 later reopened but portions of I-40 remained closed Thursday night.
