PHOENIX, AZ (3TV/CBS5) -- Monsoon storms moved through the Valley Sunday afternoon knocking down trees and knocking out power to thousands of customers.
As of Monday morning, most of the power has been restored in the Phoenix area.
Phoenix Fire Department confirmed strong winds ripped off the side of the Phoenix strip mall.
Monday, the fire department told businesses they have to close for two or three days while clean-up is happening.
"Sad to me because this is my parents only income," said Jason Nguyen. "I’m not sure how it will affect the business and all the customers."
Nguyen's parents own a nail shop in the strip mall. He said no one was there when the storm tore the building a part.
"I’ve only learned of this disaster this morning," said Nguyen. "When I came to the scene, it was really dramatic."
Employees across the street at Domino's also described the damage.
"You just don’t expect it," said Lexy Frantzen. "It’s really crazy to see a building behind us that’s been there forever to just all of a sudden have no signs on it because of the wind."

The storms hit the valley first in the Apache Junction area, then moved through Queen Creek, Fountain Hills, north Scottsdale, Cave Creek, Mesa, Gilbert and central Phoenix. By the time the storm made its way to the west Valley, it was breaking up.
The National Weather Service issued a severe thunderstorm watch for major portions of the state until 11 p.m. Sunday.
Due to the storm, parts of the Phoenix-metro area were without power. According to SRP and APS, almost 8,500 customers in Phoenix, Scottsdale and Mesa were without electricity at the height of the storm.
Early Sunday afternoon, the storms developed in the higher regions along the Mogollon Rim.
