Update, 4.45pm: A fourth person has been struck by lightning, after a severe thunderstorm swept over the city this morning.

The storm ripped through the south metro area this morning, causing havoc with the power supply, bringing down branches and causing minor flooding.

A warning was issued for the Perth metro area as the storm shifted north.

People in areas bound by Lancelin, Northam and Narrogin were told to prepare for damaging winds, heavy rainfall and possible hail.

Multiple thunderstorms are expected to hit Perth this afternoon following intense lightning early this morning.

There were just over 8300 lightning strikes between 12am to 2:30pm within a 600km radius of Perth yesterday, according to local weather-watcher Tom Marsh, who uploads minute-to minute updates at www.tkup.net from his Floreat weather station.

The peak rate was 95 strikes a minute at 7.14am, including strikes between clouds as well as from clouds to ground, he said.

Weather bureau forecaster Nadine Baillard said while the storms were easing off for now, higher temperatures would see them build up again this afternoon.

One person was hit by lightning at 4am on Wyeree Road in Mandurah and was taken to Peel Health Campus and a second person was struck at 4:30am on Brennan Promenade in Baldivis. He was taken to Rockingham Hospital.

A third person was taken to hospital by ambulance after he was struck at about 9am.

Mysterious and gigantic jets of lightning that shoot up to near the edge of space have now been observed in unprecedented detail, revealing just how much charge they pack and how they form.

More than 50 miles (80 kilometers) above Earth’s surface, extreme ultraviolet radiation from the sun reacts with air molecules to produce highly charged particles, generating an energetic region known as the ionosphere.

In 2001, scientists discovered gigantic jets of lightning arcing up from clouds in the lowest portion of the atmosphere, the troposphere, to the ionosphere. These rarities apparently are caused by Read more…
