Thousands of vacationers have evacuated a popular tourist spot in southeastern Australia as a heatwave and strong winds fuel wildfires sweeping through the region.

But with temperatures hitting 40 degrees Celsius (104 degrees Fahrenheit) Monday and blazes closing sections of the main highway, many more tourists and residents of East Gippsland are now unable to leave.

“It’s a very serious, life-threatening situation,” Bureau of Meteorology senior forecaster Kevin Parkyn told the Australian Broadcasting Corporation. Authorities warned that conditions in the forested coastal region are the worst since 2009, when the state’s Black Saturday blazes left 180 people dead.

The emergency is the latest development in a wildfire crisis that’s gripped Australia since blazes broke out months ago during the southern hemisphere winter amid a prolonged drought. The fires, which are affecting several states, have triggered an emotive debate about the impact of global warming in the world’s driest inhabited continent.

At least nine people have been killed and hundreds of homes destroyed, putting pressure on Prime Minister Scott Morrison’s conservative government, which champions the coal industry and has dismissed calls to take more steps to curb emissions.
