Western Australia assesses Cyclone Ilsa's 'path of destruction'

Emergency authorities in Western Australia were assessing damage on Saturday from a tropical cyclone that hit the state's northwest, sparing heavily populated areas but affecting several remote communities.

Ilsa, downgraded to a severe weather system, made landfall in the sparsely populated Pilbara region of Western Australia early on Friday with an intensity rating of 5, the highest.

The storm is the second extreme weather event this year in the state's northwest. “Once in a century” floods lashed the vast Kimberley region further north in January.

Western Australia Department of Fire and Emergency Services Assistant Commissioner Rick Curtis said crews were surveying damage in the “very large area” hit by Ilsa.

“There is a large path of destruction,” Curtis told ABC television, saying there had been damage to some homesteads and station properties in the region.

“It’s quite a remote part of Western Australia so getting support services to the area will take some time and effort.”

The cyclone, which set a preliminary Australian record 10-minute sustained wind speed of 218km per hour (135mph), missed the world's largest iron ore export hub at Port Hedland, before moving inland.
