A gigantic dust storm blew across Phoenix on Monday, the second storm in less than a month. Footage shot aboard a helicopter caught the incredible sight created by the beige clouds of dust.The dust storm also known as a "haboob" caused visibility problems for drivers and filled the skies with a dense cloud that blocked out the sun as it moved across residential neighborhoods.Monday's storm had winds of up to 30 miles-per-hour (48 kilometers-per-hour) and hovered three thousand feet (914 meters) over the city.
