Damage minimal as Cyclone Christine lets loose on Pilbara AUSTRALIA'S largest iron ore ports were swinging back into operation last night and emergency services were mopping up in Pilbara towns after Cyclone Christine ripped across the coast, forcing shutdowns that delayed hundreds of millions of dollars of iron ore shipments. The small towns of Roebourne and Wickham were hit hardest by the category-three storm that generated gusts of more than 170km/h when it made landfall late on Monday, uprooting trees and causing damage to homes, buildings and cars.
