Firefighters battled scores of wildfires raging across southeast Australia on Tuesday, Jan 8 as authorities evacuated national parks and warned that blistering temperatures and high winds had led to "catastrophic" conditions in some areas, Associated Press reported.

No deaths had been reported, although officials in Tasmania were still trying to find around 100 residents who have been missing since a fire tore through the small town of Dunalley, east of the state capital of Hobart, last week, destroying around 90 homes. On Tuesday, police said no bodies were found during preliminary checks of the ruined houses.

"We are shaping up for one of the worst fire danger days on record," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons said. "You don't get conditions worse than this. We are at the catastrophic level and clearly in those areas leaving early is your safest option."

Catastrophic threat level is the most severe rating applicable.

Wildfires have razed 20,000 hectares (50,000 acres) of forests and farmland across southern Tasmania since Friday. In New South Wales, the country's most populous state, the fires had burned through more than 26,000 hectares (64,000 acres) of land.
