Firefighters battling some of the most destructive wildfires to ever strike Australia's most populous state were bracing Sunday for worsening conditions, with higher temperatures and winds expected to intensify the danger in the coming days. The fires had destroyed a total of 208 homes and damaged another 122, the service said as assessment teams continued to update the tally in their search for survivors and victims. A Blue Mountains hospital was evacuated on Saturday because of the wildfire threat. The 24 patients were transported to a Sydney hospital where they are expected to stay until Wednesday at least, Health Department official Clair Ramsden said. "I'm increasingly concerned about the potential for significant fire runs and consequential damage if the weather conditions materialize like they're indicating they could over this week," Rural Fire Service Commissioner Shane Fitzsimmons told Seven Network television on Sunday. Police have charged two girls aged 12 and 13 with lighting a fire in a woodland on Sydney's western fringe on Friday. Firefighters were able to extinguish the small blaze without damage to property. The girls will appear in a juvenile court on Dec. 4, police said in a statement. It was not immediately clear what penalty they could face if convicted.
