Thunderstorms, flooding in Australia kill 10 and cause widespread blackouts

Ten people were killed in Australia after severe thunderstorms battered the country's east over the Christmas period, authorities said Wednesday, and tens of thousands of properties remain without power.

Wild weather lashed the states of Victoria, New South Wales and Queensland on Dec. 25 and 26, bringing large hailstones and torrential rains. Strong winds blew off roofs and brought down trees in some of the worst-affected areas. More than 90,000 households remained without power.

Three men were killed after a yacht with 11 on board capsized near Green Island in Moreton Bay during the storm, Queensland Police Commissioner Katarina Carrol told reporters.

People swept away by stormwater

Two women were found dead near the town of Gympie, about 180 kilometres north of the state capital of Brisbane, after they were swept away in flooded stormwater drains, police said.

A nine-year-old girl was found dead after going missing in a drain in Brisbane's south.

Authorities warned fast-rising rivers and streams could burst banks inundating campgrounds, which usually become crowded during the Christmas and new-year weeks.

A man was found dead in a campground in Victoria after flash flooding, police said. It's believed he camping with a woman who was found dead on Tuesday.

Two people were killed by falling trees.

The storm took down a concrete power line, which was "pretty significant and unprecedented," Queensland Premier Steven Miles said during a media briefing. Miles said the damage from Cyclone Jasper, which hit the state earlier this month, and the latest thunderstorms could be in "the billions."

'Escalating climate consequences'

Australia's Bureau of Meteorology has forecast further rain, though the wild weather was expected to ease later Wednesday.

"Thankfully today, we are not expecting to see quite as widespread thunderstorm activity, but there is still a risk of severe thunderstorms right across the east coast," forecaster Jonathan How told ABC television.

The storms follow intense heat waves in the spring that resulted in several bushfires and after Cyclone Jasper caused widespread damage.

"When you start to piece together the experiences of this summer so far, it is clear that we are living through an era of escalating climate consequences," said Simon Bradshaw, research director at the independent non-profit Climate Council.

As Australia battles rain in the east, several regions in the west, in contrast, are fighting fires. A volunteer firefighter was killed while responding to a bushfire, media reported.

Australia's December-February summer is under the influence of the El Niño phenomenon, which can cause weather extremes ranging from wildfires to cyclones and prolonged droughts.
