If today seems a lot like Tuesday, weatherwise, it's not déjà vu.

It's the monsoon.

Hot, sticky days with temperatures lingering in the low 100s will be followed by cooler evenings with a 30 percent chance of showers each night through at least Friday.

Hopefully, however, the welcome cool-down from monsoon rains won't be as hard on Tucsonans as the storms were on west-siders Monday.

The Tucson Fire Department responded to nearly 20 calls for downed wires; five for arcing wires; five for small fire-related issues such as brush, fence and tree fires; and more than 30 for fire alarms, Capt. Barrett Baker, spokesman for the Tucson Fire Department, said in a news release.

Firefighters also were called to rescued three people trapped in a car when a power pole fell on the vehicle in the 2500 block of West Ironcrest Drive near North Greasewood Road and West Ironwood Hill Drive. Tucson Electric Power workers secured the power lines "and safely escorted the three occupants away from their vehicles," Baker said.

Power lines also fell on a second vehicle.

No one was injured in either incident.

Downed power lines should immediately be reported by calling 911.

"Always assume that downed power lines are energized and never attempt to move them," Baker said.

Tucson Electric said at least 17 poles would need to be replaced after the storm, including 12 along West Ironwood Hill Drive.

Utility crews were still working Tuesday evening to restore power to customers.
