Storm clouds built up during the day in Perth yesterday as the temperature hit 38C.

A dramatic electrical storm then swept through southern suburbs at night.

These spectacular pictures were taken by part-time photographer Dan Avila about midnight last night as he overlooked Coogee beach and South Fremantle.

He said the lightening was so intense he felt like it was going to crack his house in half.

Despite the storm overnight, rainfall was isolated in Perth.

Bureau of Meteorology senior forecaster Matt Boterhoven said Perth recorded slight rainfall of 2mm, Jandakot received 4.2mm while Meekatharra recorded 44mm.

“Meekatharra had a good drop of rain from a thunderstorm,” he said.

“We have got the chance of another thunderstorm today. It’s 28C and very humid out there.”

The WA Flood Warning Centre has also issued a flood warning for Nullagine.

"Isolated rainfall has been recorded in the De Grey catchment for the 24 hours to 9am Wednesday which include 10mm at Bonney Downs," the centre said.

"Isolated thunderstorms are expected for the rest of Wednesday and for the remainder of the week.

"The Nullagine River at Nullagine is currently above the minor flood level. Areas of minor flooding around Nullagine are expected to continue throughout Wednesday and into Thursday.”
