Residents in Perth’s east and north-east have been urged to flee as two bushfires threaten homes.

Emergency warnings have been issued for the two blazes, one around Kenwick, in the city’s east, the other further north in Upper Swan.

The Kenwick fire broke out around midday (AWST) and has since burned along Boundary Road and into the Kenwick Wetlands.

People in the area, in the parts of Kenwick, Wattle Grove, Maddington and Beckenham bounded by Welshpool Road East, Tonkin Highway, Kenwick Road, Brixton Street and Roe Highway, have been told to leave to the south if it is safe to do so.

“You are in danger and need to act immediately to survive. There is a threat to lives and homes,” the emergency warning states.

“Homes in Bickley Road, Brook Road and Boundary Road are under threat by fire now.”

Fire crews are on the scene battling the fire.

It is not clear if any buildings have been lost to the blaze.

Further north, people in Upper Swan, Bullsbrook and Walyunga National Park – those east of Great Northern Highway, north of the Swan River and south of Stock Road – have also been told to evacuate, this time to the west.

The northerly blaze was first reported just before 1pm (AWST), and is still uncontained and uncontrolled, despite the efforts of firefighters.

Perth has sweated through hot conditions today, with the mercury reaching 36.4 degrees at the airport, in the city’s east, shortly before 1:30pm today, and wind gusts reaching 43km/h.

Temperatures for metropolitan Perth are forecast to hit 35 degrees tomorrow, before rising to as high as 39 over the weekend.
