Severe weather has cut power to parts of Perth Airport, delaying check-ins, flights, and leading to the delay of the city's flight schedule, after a high-voltage transmission pole was damaged.
Travellers at Western Australia's largest airport have been warned flights will be impacted, while some terminals are without overhead lighting, an airport spokesperson told AAP.
Flights scheduled to arrive at Perth that have not yet departed have been delayed until further notice, Perth Airport said on Tuesday afternoon.
Flights scheduled to depart after 7.30pm have also been delayed.
Planes already in the air expected to arrive in Perth will be welcomed to the airport as normal, the statement said.
"Passengers should expect delays or cancellations."
The outage on Tuesday is linked to storm damage causing a blackout for several thousand people in Perth's eastern foothills, a Western Power spokesperson said.
While the entire airport is not affected, repairing the damaged transmission pole is expected to take six to eight hours.
"As part of our hazard response, our crews have found a transmission pole that has been damaged resulting in high voltage conductor hanging close to the ground, posing a safety risk," the spokesperson said.
To carry out repairs, surrounding power supply lines had to be cut.
The airport spokesperson confirmed services had been delayed.
"The severe weather experienced over the past 24 hours has caused damage to power lines supplying Perth Airport," the spokesperson said in a statement.
"The safety of everyone who works in or is travelling through our airport remains our highest priority."
Western Power is working with Perth Airport to repair the power lines, and services will be impacted temporarily as the work continues, the spokesperson said.
Critical operations are being supported at Perth Airport by backup generators.
