Australia’s east faces days of storm danger this week, with warnings increased after a destructive storm swept through Alice Springs, downing trees and knocking out power to thousands of homes.

Emergency crews were sent to Alice Springs on Tuesday after Monday’s storm toppled trees and power lines, pelted the town with large hailstones and caused widespread damage.

It brought winds of nearly 100km/h and led to 100 calls for help to the State Emergency Service.

“Our thoughts are with the many Alice Springs residents who have been affected by this destructive storm. We are here to help you get back on your feet as soon as possible,” Northern Territory Chief Minister Lia Finocchiaro said.

NT Treasurer Bill Yan said it was fortunate no injuries had been reported despite the significant damage caused by the storm, including trees that fell onto cars.

“We want to keep it that way. We need people need to stay safe with powerlines and trees down all over town,” he said.

The State Emergency Service responded to more than 100 calls for help.

On Tuesday, the weather bureau warned parts of NSW and Queensland faced the chance of similar weather all week.

“There’s a risk of severe thunderstorms in central Australia… and then the east coast. So the Mid-North coast and Northern Rivers district of NSW, as well [as] the south-east coast of Queensland,” senior meteorologist Sarah Scully told Today.

“These storms could bring damaging wind gusts in excess of 90km/h, large hail, or heavy rainfall that could lead to flash flooding.”

Tuesday’s warnings come after Sydney sweltered through maximum temperatures of 35 degrees on Monday. A much more comfortable 22 was expected on Tuesday, with rain and cloudy weather as a cool change swept up from the southern states.

Forecaster Weatherzone said daily storms were likely in states and territories.

“Some of these thunderstorms are likely to be severe,” it wrote.

“The majority of this week’s wet and stormy weather will occur over the eastern two-thirds of the country, with Queensland and NSW likely to be active areas for intense storms and heavy rainfall.”

Weatherzone said central Queensland would be a focus area for potentially severe thunderstorms this week, with areas of heavy rain likely on multiple days bringing increased flood risks.

“South-east Queensland also has a chance of thunderstorms on several days this week,” it said.

“Storms were already developing over south-east Queensland and north-east NSW on Monday afternoon, and further storms are likely in both areas on Tuesday, possibly becoming severe.”

Elsewhere, Alice Springs is “not out of the woods yet”, with a repeat of Monday’s storm predicted for Tuesday afternoon and evening.

“There’s still the chance of severe thunderstorms again bringing damaging wind gusts, large hail and the chance of heavy rainfall,” the Bureau of Meteorology’s Robert Urbaniak said.

“Unfortunately another day of it, but after that should settle down somewhat.”
