Friday's midafternoon storm wreaked havoc on Tucson's south and west sides while dropping more than 2 inches of rain in Marana.

Staff at Van Buskirk Elementary School, 725 E. Fair St. off South Park Avenue, had to be evacuated after a microburst blew sections of roof off the building and knocked down several utility poles in front of the school, said Capt. Chris Jurvig, spokesman for the Tucson Fire Department.

In the Foothills, crews from the Rural/Metro Fire District were called to a house fire in the 4700 block of north Via Molino near East Snyder Road and East Catalina Highway, likely sparked by lightning, said Capt. Grant Cesarek, spokesman for Rural Metro.

An Oro Valley teen had to be fished out of a wash off North Oracle Road south of Catalina State Park. The boy entered the wash when it was dry, but "while he was there, a flash flood came through, stranding him on a small sand island," Battalion Chief Josh Hurguy, Golder Ranch Fire District spokesman, said in a news release.

At the storm's peak as many as 9,000 Tucson Electric Power customers were without electricity because of downed power lines. Most customers had their power restored by evening, the utility said.

Tucson International Airport received just a trace of rain, but some areas of town received more than 1 1/2 inches while others parts were dry.

The weekend is expected to remain partly cloudy with a slim chance of showers and temperatures in the high 90s and low 100s, according to the National Weather Service.
