Almost 45,000 Sydneysiders are still without power today, after severe storms caused extensive damage to the electricity network yesterday.

NSW was in a state of extremes as severe storms lashed Sydney, downing trees and powerlines and cutting off power to thousands of homes, while snow fell in Thredbo, and parts of the state sweltered.

Power was cut to 52,000 homes in less than 10 minutes after the intense burst of wild weather swept through Sydney, and while Ausgrid is currently working on restoring the outages, the company said it may take some time “due to the level of damage.”
