Emergency services are working to rescue people in Perth’s northern suburbs after flash flooding left people trapped in their cars.

A Department of Fire and Emergency Services spokeswoman said crews were called to Winton Road, Connolly Drive, and Hester Avenue in Joondalup after reports of multiple cars being caught up in the floods.

More than 40 calls have been made to SES so far due to the torrential rain in Clarkson, Ridgewood, and Nowergup.

Most of the calls have been as a result of flooding and water ingress in homes and some calls have been for hail and roof damage.

Ocean Keys Shopping Centre in Clarkson has been damaged with water flooding through the roof.

Main roads warned motorists Mitchell Freeway Northbound has been flooded at Neerabup road, Clarkson.

The Department of Fire and Emergency Services has issued an alert for severe thunderstorms in parts of the Perth Metropolitan and Midwest-Gascoyne.

Affected areas include Gingin, Joondalup, Jurien Bay, Lancelin and Yanchep.

Residents in these areas should take action by finding a safe shelter away from trees, powerlines, storm drains and streams.

If driving, don’t drive through waters of unknown depth, and be alert for hazards.

The northern suburbs have been smashed by heavy rainfall, with some areas even being battered by hail.

“There is certainly an alignment of thunderstorms extending from the north over the northern suburbs,” Bureau of Meteorology said.

“Right now, it’s not too far from the Perth CBD, so there is some potential for rainfall.

“However, it is a slow-moving feature, and I’m expecting it to weaken over the next few hours but there is some potential that we may get something.”

Footage taken by locals show just how intense the rainfall has been.

“Very welcome news to hear the sound of rain!” a resident wrote in a local group.

Others confirmed that nearby suburbs were also copping the deluge.

The 30-day dry spell has been intense in Perth however, it’s not as unusual as it might seem.

“It is a long spell, but we have had long spells before where we haven’t had much rain, especially through April. It is unique, but it’s not like it’s never happened before,” the Bureau of Meteorology said.

Perth is expected to see a sunny week ahead with only a 0-5 per cent chance of rain.
