A swirling,Pretty Ex-Girlfriend intense low pressure system spawned severe thunderstorms that took out the state of South Australia's entire power grid on Wednesday local time.

As of Thursday, the city of Adelaide and most of the state still lacked power, as more showers and thunderstorms, many of them bearing damaging winds, worked their way across the Adelaide area once again. Adelaide has a population of about 1.2 million.

Australian media are calling the storm among the worst in at least a half-century, if not longer.

According to The Guardian, the blackout was caused when high winds in the northern parts of the state took out five or six electrical transmission towers, which caused the entire state's network to shut down at around 3:48 p.m. local time on Wednesday.

The South Australia premier, Jay Weatherill, said that the shutdown of the entire grid was a step taken to isolate the problem to South Australia and avoid cutting power to all of Australia.

"This is a major weather event and the system has reacted a it is supposed to react," Weatherill said, according to The Advertisernewspaper. "The system operates in this way to shut the system down and is now being restored in regard to those protocols."

Flights into and out of Adelaide were halted for a time due to the lack of power in the terminal buildings, traffic came to a standstill without traffic signals, and other power-dependent systems also experienced disruptions.

The storm is expected to swirl its way southeastward, bringing strong winds and showers to Tasmania through the weekend.
