PHOENIX (CBS5) -
North Phoenix residents on Monday continued to clear the mess left from a macroburst that produced winds in excess of 100 mph Saturday night that snapped power poles, toppled trees and cut power to 33,000 utility customers.
The National Weather Service defines a macroburst as "a convective downdraft with an affected outflow area of at least 2 1/2 miles wide and peak winds lasting between five and 20 minutes. Intense macrobursts may cause tornado-force damage of up to F3 intensity."
The storm damaged part of Paradise Valley Hospital. Crews were out early Sunday cleaning up the mess on the roof.
At the height of Saturday night's storm, Arizona Public Service said 23,000 customers were without power. Salt River Project identified 10,000 households that were offline, mostly in the Mesa and Apache Junction areas.
By Sunday afternoon, APS reported 3,800 customers still remained without power. Most are located in neighborhoods south of Bell Road along the SR51 corridor. Meantime, SRP said that by 1 p.m., service had been restored to its customers.
CBS 5 meteorologist Steve Garry said other wind gusts during the height of the storm included:
61 mph - Deer Valley
43 mph - Scottsdale
35 mph - Mesa (Falcon Field)
35 mph - Sky Harbor International Airport
24 mph - Glendale
High winds, lightning, hail, dust and rain pelted parts of the area as monsoon moisture tapped into the energy of an upper-air disturbance.
Residents reported trees were uprooted and fell onto rooftops.
One family in the 15000 block of North 38th Street escaped injury when their roof caved in from a toppled tree.
The lightning was intense, with what many residents described as a spectacular display.
