Phoenix storm knocks out power

A summer storm in Phoenix brought lightning, strong winds and sheets of rain that flooded streets, delayed flights and left thousands of people temporarily without power Thursday evening.

The storms made for a frightful commute for motorists as torrents of water poured from darkened skies onto Phoenix roadways and power outages turned off stoplights. Emergency vehicles rushed through the opposite lane of traffic amid broken tree limbs as cars clogged the other side of the road.

Huge trees were uprooted, blocking traffic, and especially heavy street flooding was reported in nearby Tempe.

The roof of an unoccupied furniture store collapsed, apparently under the weight of water, and fire authorities said there was also flooding at a neighboring supermarket. No injuries were reported.

The Phoenix Zoo will close Friday while workers clean up and assess damage to the grounds, mostly from downed trees. All animals were reported safe and accounted for, Phoenix radio station KTAR reported.

Water bubbling up from the drainage system pushed the covers off several manholes outside Phoenix Sky Harbor International Airport, forcing drivers to navigate around fountains of water as they picked up passengers. Some flights were delayed and diverted around 5:15 p.m. because of heavy rain, lightning and 50 mph gusts.
