Damage caused by Tropical Cyclone Christine in Western Australia's Pilbara region appears to be limited to trees and fences, with a few minor roof leaks.

Christine crossed the coast between Whim Creek and Roebourne early yesterday as a category-three cyclone, but has since been downgraded to category two as the system weakens and tracks southeast.

The Bureau of Meteorology said the cyclone was 220km south of Karratha and 75km northwest of Paraburdoo, and moving south at 20km/h.

Roebourne councillor Robin Vandenberg said many trees had fallen but there was little structural damage.


He said on a scale of one to 10, he would rate the cyclone as a seven in severity.

Vandenberg has lived in his house for 30 years and said the older buildings had stood the test of time against cyclones, while some of the newer buildings had suffered leaks.

The all-clear has been given for people between De Grey and Mardie, including Marble Bar, Port Hedland, South Hedland, Whim Creek, Karratha and Dampier.
