High winds can damage poles and lightning strikes blow fuses. Tucson Electric Power says monsoon mounts its annual assault on their grid every year.
Since last Friday, there have been about 15,000 people throughout Southern Arizona who have lost power for a time.
TEP says monsoon is to blame for the power outages.
"They were all tied back to the weather that we were seeing but they can be classified in different ways, safe to say that the majority of those outages were caused by storms."
TEP says when multiple outages happen, they prioritize repairs to the largest number of people as quickly as possible. It is also recommended that people have a plan for if the power should go out for a long period of time.
"We recommend that customers keep an eye on the weather and are generally aware that there might be stormy conditions that could lend themselves to outages. It's a good idea to keep your mobile devices charged and to have a flashlight and plenty of batteries on hand."
