Heavy rainfall and Damaging winds over the Kimberley with Tropical Cyclone Dianne, extending south to the Pilbara and North Interior during today.

Weather Situation: Tropical Cyclone Dianne made landfall just to the east of Cockatoo Island early this morning, and is moving southwards, just inland from the coast. It is expected to pass east of Derby at about midday. Dianne is expected to weaken below tropical cyclone strength Saturday morning.

HEAVY RAINFALL which may lead to FLASH FLOODING is forecast for the northern Kimberley and spreading inland throughout the warning area as the system moves inland over the weekend.

Six-hourly rainfall totals of 70 to 100 mm are possible, with isolated totals increasing to 150 mm along the coast and extending inland during Saturday. 24-hourly totals of 100 to 150 mm are possible, with isolated totals up to 250 mm.

DAMAGING WINDS with gusts to 100 kilometres per hour are possible and could cause DAMAGE TO HOMES AND PROPERTY as the decaying system moves further inland today. This risk of damaging wind gusts sits on the southern flank of the decaying system, and may affect areas west of Fitzroy Crossing.

A separate Tropical Cyclone Advice is current for DAMAGING WINDS and HEAVY RAINFALL for adjacent parts of the Kimberley coast. See http://www.bom.gov.au/cyclone/index.shtml for more information.

Locations which may be affected include Fitzroy Crossing, Kalumburu, Kuri Bay, Mitchell Plateau and Mount Barnett.

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.
* Close your curtains and blinds, and stay inside away from windows.
* Unplug electrical appliances and do not use land line telephones if there is lightning.
* If boating, swimming or surfing leave the water.
* Be alert and watch for hazards on the road such as fallen power lines and loose debris.
* Keep away from flooded drains, rivers, streams and waterways.
* Be careful of fallen trees, damaged buildings and debris.
