For the second time this month, a wall of dust moved through the Phoenix area Monday evening, turning the sky brown. The dust wall, which was estimated at 3,000 feet high, reduced visibility and caused some flights out of Phoenix Sky Harbor International Airport to be delayed, according to the Associated Press.
A massive dust storm — which was estimated to be 50 miles wide — hit the Phoenix area earlier this month. This latest storm was not a big as the last, Austin Jamison, a National Weather Service meteorologist, told the AP.
