Phoenix hit by 4th 'haboob' so far this summer

A cloud of dust has swallowed Phoenix at sundown for the fourth time this summer on the hottest day on record in August.

A strong thunderstorm system late Friday afternoon pushed a brown cloud over most of the city, which hit a record 117-degrees hours earlier.

Phoenix has been hit by the wall of dust, known as a haboob, on July 5, July 18 and Aug. 19.

Friday's haboob didn't appear to be as severe as the previous ones.

Weather experts say such massive dust storms only happen in Arizona, Africa's Sahara desert and parts of the Middle East because of dry conditions and large amounts of sand.

The 117 degrees topped Phoenix's previous high of 114 for August, set 10 years ago.

Phoenix hit 118 degrees on July 2.
