SYDNEY      -        Australian authorities urged another mass evacuation across the heavily populated southeast on Thursday as a return of hot weather fanned huge bushfires threatening several towns and communities. Victoria state Premier Daniel Andrews urged communities to be on alert ahead of the extreme conditions.

“If you receive instructions to leave, then you must leave,” Andrews said in a televised briefing. “That is the only way to guarantee your safety.”

Parts of Kangaroo Island, a wildlife-rich tourist spot off the southeast coast where Prime Minister Scott Morrison on Wednesday made a plea for foreign tourists not to be deterred by the fires, were again evacuated on Thursday.

 “I urge everyone to heed warnings, follow advice, and to head to the east part of the island, which is deemed safe at this point,” South Australia Fire Chief Mark Jones said in a separate briefing in Adelaide.

Twenty-seven people have been killed this fire season, according to the federal government, as the monster fires have scorched through more than 10.3 million hectares (25.5 million acres) of land, an area the size of South Korea.

Thousands have been made homeless and thousands have had to evacuate repeatedly because of the volatility of the fires. Residents of the coastal town of Mallacoota, where thousands of people were stranded on a beach for days until a military evacuation that only ended on Wednesday, were among those again advised to flee.

“If we evacuate, where do we go?” said Mark Tregellas, who spent New Year’s Eve on a boat ramp as fire destroyed much of his town, and one of about 1,000 people who decided to stay.

“The electricity is slowly coming back but everyone is reliant on generators, and fuel for those is very limited,” he told Reuters by telephone from his house.

The Australian Bureau of Meteorology reported only 6% of typical annual rainfall last year, while daytime temperatures were more than 2 degrees Celsius (3.6 degrees Fahrenheit) above normal: “Australia’s getting warmer, the fire season’s getting longer and the severity of the fire weather during that season is getting more frequent and severe.”

The fires have emitted 400 megatonnes of carbon dioxide and produced harmful pollutants, the EU’s Copernicus monitoring program said.

 Smoke has drifted across the Pacific, affecting cities in South America, and may have reached the Antarctic, the U.N. World Meteorological Organization said.
