An emergency warning has been issued for a fire burning at Kwolyin and Pantapin in the shire of Bruce Rock in Western Australia's southwest. Authorities say the fire started in Kwolyin and people should leave the area if they can. "You are in danger and need to act immediately to survive. There is a threat to lives and homes," the alert read. Another fire in the same shire closer to the coast is burning at a watch and act level of alert. Seven districts are braced for extreme fire danger with the whole state on alert. An earlier emergency alert in the Pilbara region further north in the state has been downgraded after threatening lives and homes. It is currently at watch and act. An emergency fire alert was issued on Saturday night for people at or near Wandoo Camp in Pannawonica in Ashburton Shire, with residents told to shelter in place. Four hours later the warning was downgraded to watch and act as Wandoo Camp was no longer under imminent threat. Crews remain on the scene, back-burning and fighting the lightning-lit fire as it moves in an easterly direction. "It is out of control and unpredictable," the alert advised. Extreme fire danger ratings have been forecast on Sunday for the districts of Yarra Yarra, Swan Inland North, Swan Inland South, Geographe, Capes, Brockman and Mortlock. The danger rating is high for 32 other fire districts in the state. It comes as firefighters continue to battle a fire that ripped through dozens of tinder-dry, semi-rural properties near Perth, destroying 18 homes. Previously burning at emergency level, the Perth blaze was reduced to a watch and act warning on Friday afternoon, although authorities warned it could take days to bring the fire, which has a 64km perimeter, under control. Watch and act alerts remained in place for parts of Jandabup, Melaleuca, Wanneroo and Marginiup in the City of Wanneroo on Sunday morning. Residents were being warned there was still a possible threat to lives and homes as the fire continues to burn and the weather forecast remained unpredictable, with a weekend of 39C temperatures. A severe storm warning is current for residents in parts of the Perth metropolitan and southwest districts. Federal Emergency Management Minister Murray Watt has flagged disaster recovery assistance - jointly funded by the federal and WA governments - will be made available to those affected by the Perth fire.
