Cyclone Joyce forms off WA coast

Ben Domensino, Thursday January 11, 2018 - 12:21 EDT

Tropical Cyclone Joyce has formed off the north coast of Western Australia and is expected to make landfall on Friday or Saturday.

Joyce is the third cyclone to be named in Australian waters so far this season and should become the second to cross the coast.

At 8am WST on Thursday, Cyclone Joyce was located about 140km to the north northwest of Broome, moving towards the southwest at 6km/h. Wind gust near its core were estimated to be reaching 95km/h at the time, which is the minimum threshold for a category one cyclone.

Conditions will be favourable for Cyclone Joyce to strengthen further during the next 24-48 hours as it approaches Western Australia's northern coastline.

At this stage Joyce is expected make landfall somewhere to the east of Port Hedland as a category two or three cyclone on Friday. However, there is some disagreement between forecast models regarding the system's likely movement during the next couple of days, so this track may alter.

Moisture laden onshore winds to the east of the cyclone are already causing heavy rain and thunderstorms across the Kimberley District. Derby received 148mm during the 48 hours up to 9am today, which is more than half of its monthly average at this time of year.

Anybody living along the Pilbara and west Kimberley coasts should prepare for the possibility of being impacted by a tropical cyclone in the coming days and monitor the latest advisories for updated details.
