A severe thunderstorm Sunday night knocked out power to thousands, caused damage around the Valley and led to interruptions at Phoenix Sky Harbor International Airport.

The storm moved into the Valley from the north just before 10 p.m. It dropped more than an inch of rain in some places.

The heavy rainfall led to ponding on Interstate 10 in the Deck Park Tunnel.

The tunnel was reopened to traffic around 11:30 p.m.

APS and SRP both reported thousands of customers were without power due to downed power lines and tripped substation breakers. For the latest power outage information, click here for APS outages and here for SRP outages.

Sky Harbor said it put a ground stop in place for almost an hour as the storm brought lightning, wind gusts greater than 60 miles per hour and reduced visibility to less than a mile. Airport officials said flights were delayed and diverted but did not immediately have a specific number of flights impacted.
