Cape Leveque to Port Hedland, including Broome and Port Hedland, as well as remaining inland parts of the far western Kimberley and far northeast Pilbara.

Details of Tropical Cyclone Joyce at 2:00 pm AWST:
Intensity: Category 1, sustained winds near the centre of 75 kilometres per hour with wind gusts to 100 kilometres per hour.
Location: within 35 kilometres of 17.3 degrees South 121.7 degrees East, estimated to be 90 kilometres northwest of Broome and 155 kilometres north of Bidyadanga.
Movement: south at 9 kilometres per hour.
The uncertainty in the forecast track means that it is still possible the system could impact coastal parts of the central Pilbara late on Friday or during Saturday.
GALES with gusts to 100 kilometres per hour are possible today between Cape Leveque and Bidyadanga. GALES may extend to areas between Bidyadanga and Wallal Downs during Thursday evening, and to areas between Wallal Downs and Port Hedland on Friday. If the system tracks further to the west then GALES are possible in areas between Port Hedland and Karratha on Saturday.
DESTRUCTIVE winds with gusts to 130 kilometres per hour may develop in coastal parts between Beagle Bay and Wallal Downs, including Broome, on Thursday evening if the system is close enough to the coast. DESTRUCTIVE winds may extend to Pardoo Roadhouse during Friday.
VERY DESTRUCTIVE winds with gusts to 180 kilometres per hour are possible near the centre of the system on Friday, if it develops into a severe tropical cyclone.
Tides will be higher than expected between Cape Leveque and Pardoo Roadhouse.

Widespread daily rainfall totals of around 50 to 150 mm are expected with isolated heavier falls of 150-300 mm possible. Flood Watches and Warnings are current.
