Aug. 26 (UPI) -- Planes are flying out of Phoenix again Tuesday after dust storms blew through central Arizona on Monday, grounding flights and knocking out power to thousands.
The Federal Aviation Administration announced a flight stoppage around 9:30 p.m. EDT at Phoenix Sky Harbor International Airport due to the weather before lifting the restrictions about an hour later.
Video of the storms showed walls of dust -- known as haboobs -- move across the Phoenix metropolitan area Monday. More than 40,000 people lost electricity during the event, which was created by winds from thunderstorms that lift dust and debris skyward.
As of 1:20 p.m. EDT Tuesday, over 3,400 customers were without power in Arizona.
Haboobs can be thousands of feet high and stretch for miles. The weather phenomenon can roll in with little warning and severely decrease visibility.
