Residents in north-west Western Australia are being urged to remain prepared for a cyclone. The weather bureau predicts cyclonic activity will increase in the next fortnight. The bureau says there is a heightened chance a cyclone will threaten the north-west coast by mid-February. Two cyclones have already formed off the West Australian coast this northern wet season. North-west Western Australia weathered Cyclones Helen and Melanie without major damage to life or property. The bureau predicts two further cyclones could threaten Western Australia before the wet season ends.
