 A massive dust storm moved through the Phoenix area Friday evening, knocking out power to more than 10,000 Salt River Power electricity customers and diverting at least one flight bound for Phoenix Sky Harbor International Airport. Visibility could be reduced to less than a quarter of a mile in some areas. #abc15wx pic.twitter.com/EPN0w2Zcnt — Amber Sullins (@AmberSullins) July 26, 2014 
 
 The National Weather Service in Phoenix says the storm could last until 7 p.m. local time in Maricopa and Pinal counties. The NWS encouraged drivers who encounter severely reduced visibility to pull off the road as far as possible and park with vehicle lights off while keeping feet off the brake pedal.
– Thousands of Phoenix residents lost power when a huge dust storm rolled in yesterday evening, reports NBC News. The storm arrived in time to mess up the rush-hour commute and also temporarily forced a halt to incoming flights at the Phoenix Sky Harbor International Airport, reports the Arizona Republic. A storm like this is called a haboob, which NPR explains is from the Arabic word for a summer dust storm. See ABC15 for a collection of photos.
