Volunteers in the southern zone of the State Emergency Service responded to more than 180 jobs over the weekend.

Mangoplah was deemed a "particular concern", according to an SES spokesperson, due to the significant damage caused by the wind.

Resident Donna McBride said the storm seemed to come out of nowhere, and it felt like a scene from The Wizard of Oz.

She was home by herself when the wild winds hit and had to hold the door closed to make sure her terrified pets did not get outside.

"Nearly the whole roof has come off except for a bit at the back," Ms McBride said.

"The verandah inside got smashed up, and the windows blew out, and so the dirt blew in."

Ms McBride has lived in Mangoplah for five years and the Riverina for 30, but said she had never witnessed such extreme weather.

She said it had been fantastic to see the community rally to help each other. "It feels like all of Mangoplah has come to see if we need anything," Ms McBride said.

Structures at the town's AGnVET Services branch were destroyed or damaged by the ferocious winds, with one grain storage shed's roof torn off and left crumpled. Manager Nathan Stoll said only minutes before the storm ripped through, there had been 10 people on site, but most had left to help at the scene of a fire.

He said if they had all still been there, someone would have undoubtedly been hurt.

"We have lost a reasonable amount of grain and significant damage to infrastructure," Mr Stoll said.

"I have been amazed by the support we have had here with local farmers offering whatever support they could give."

Paul Baker spent Sunday and Monday cleaning up after a gum tree was uprooted and damaged his fence line and shed.

"You could see it was raining and the storm was coming from The Rock," he said.

"It started with the thunder and then the rain and then the hail and the wind.

"We have lived out here for about 30 years and I probably have not seen anything like that in 25 years."

Essential Energy crews had to restore power to thousands of customers in the Riverina after storms caused severe damage to the electricity network in towns such as Mangoplah, Cootamundra, Temora, Harden, Cowra and Grenfell.

The network at Mangoplah was significantly damaged after three power poles and 10 powerlines were destroyed.

As of Monday afternoon, some residents were still without power.
