Multiple lightning-caused brush fires are burning near the Valley following a series of monsoon storms this week.
Crews are fighting one blaze, named the Salt Fire, that is burning on the north side of Highway 188, a couple of miles east of the 188/288 junction.
It's estimated to be about 13,000 acres in size as of Thursday morning, up from 2,700 acres in size Wednesday, the U.S. Forest Service says.
SRP officials say the fire is threatening power lines that bring energy to the Valley and they are asking customers to reduce their electricity use from 3-9 p.m.

The Rolls Fire is also burning in the Tonto National Forest area following lightning on Tuesday evening.
Officials say it is burning in the Rolls OHV area, northeast of the Butcher Jones Recreation Area.
As of Wednesday morning, it's estimated to be about 1,200 acres in size with no containment.
No evacuations have been put in place, but there are some road restrictions, including along Bush Highway to Saguaro Lake. The lake will remain open, officials say.
Other smaller fire reports have been made in the Tonto National Forest area. Forest Service officials say "firefighters are working to suppress these fires as quickly and safely as possible."
Fire restrictions are in effect.
