For people in Pilbara and parts of Kimberley, Gascoyne and North Interior districts.
Issued at 4:26 pm Friday, 12 January 2018.
At 4:00pm AWST Category One Tropical Cylone Joyce was estimated to be 30km south-west of Wallal Downs and 195km east of Port Hedland, moving south-west at 12 km/h.
A Tropical Cyclone Warning is current for communities between Bidyadanga and De Grey and inland to Marble Bar. Please refer to the details here:
While a Tropical Cyclone Warning remains in place, heavy rainfall and damaging winds associated with Tropical Cyclone Joyce will impact areas outside this Warning area on Friday and into the weekend.
Tropical Cyclone Joyce is likely to weaken into a Tropical Low as it moves inland overnight. It is expected to bring HEAVY RAINFALL that may lead to FLASH FLOODING, with possible DAMAGING WIND GUSTS to 100 km/h near the centre. Widespread daily totals of 50-100mm are expected across the warning area, with isolated heavier totals of 100-250mm possible near the system's centre. Possible rainfall totals will gradually ease as the system weakens.
HEAVY RAINFALL that may lead to FLASH FLOODING, and DAMAGING WIND GUSTS will lie over the Pilbara and western parts of the Kimberley and Interior Districts during Friday night and Saturday morning before extending southwest into the northern Gascoyne during Saturday afternoon and to central parts of the Gascoyne in the evening.
Heavy rainfall is likely to extend through the southern Gascoyne and into northern parts of the South West Land Division during Sunday as the low continues south-west. However, there is still some uncertainty as to its exact path and therefore where the heaviest rainfall will be.
The heaviest rainfall total recorded in the 24-hr period until 4:00pm Friday was 205.8mm at Mandora.
A Flood Watch has been issued for the following catchments: Pilbara Coastal Rivers, Fortescue River, Ashburton River and Gascoyne Coast Rivers. For further details please refer to http://www.bom.gov.au/wa/warnings
Locations which may be affected include Karratha, Meekatharra, Mount Magnet, Newman, Paraburdoo, Port Hedland and Tom Price.
Conditions will gradually ease from the north as the low moves south-west.
The Department of Fire and Emergency Services advises that people should:
* If outside find safe shelter away from trees, power lines, storm water drains and streams.

* Be alert and watch for hazards on the road such as fallen power lines and loose debris.
