A 17-YEAR-old girl was electrocuted - and two friends who came to her rescue were injured - in Geraldton early this morning after she stepped on live power lines following yesterday's wild storm.

The girl was electrocuted about 2.30am this morning when she stepped on a live power line that was connected to a street light on Augustus St.

Police spokeswoman Ros Weatherall said two youths who tried to help the victim were injured.

A 17-year-old girl was badly hurt when she tried to pull her friend off the wire. She was flown to Royal Perth Hospital for treatment and is in a serious condition.

A courageous 17-year-old boy who then dragged the two girls off the fallen line is understood to be in Geraldton hospital receiving treatment for burns.

Investigators from the Office of Safety and Energy are travelling to Geraldton to investigate the tragedy.

EnergySafety director Ken Bowron said the regulator was working with Western Power and police to prepare a report for the coroner."Two of her friends also received shocks and burns, and are in hospital. One is in a serious condition," Mr Bowron said.He said the girl's death was a reminder for others about the dangers of stepping on or touching wires that have fallen to the ground.Mr Bowron said as ex-cyclone Bianca brought storms to the coast today more wires could fall to the ground."Do not touch any wires. Keep yourself and others well away from the wires and call Western Power to report such incidents on 13 13 51," he said.

Meanwhile, an 88-year-old woman was killed in a horror car accident during yesterday's storm near York.

The woman was driving along Waterfall Rd about 3.30pm during the thunderstorm when her car ran off the road and down an embankment.

The car caught fire and the woman died at the scene.
