Rescue crews are cleaning up after a severe storm cut power to regional communities and damaged more than 100 properties.

Emergency crews responded to more than 120 reports of damaged properties after a severe storm impacted the Riverina region, in southwest NSW, on Saturday afternoon.

The towns of The Rock and Yenda were the worst hit, with widespread power outages, uprooted trees and damaged roofs.

Griffith, Wagga Wagga and Coleambally were also impacted.

NSW SES southern zone commander Chief Superintendent Ben Pickup said the storm came through the area about 3pm.

Despite the widespread damage, he said there were no reports of injuries or major infrastructure damage.

“We have 15 teams of SES crews on the ground alongside VRA, NSW RFS, and Fire and Rescue NSW who will be working through the various requests,” he said late on Saturday.

“There are widespread power outages with many trees bringing down powerlines.

“Our priority is getting through the various damaged properties and undertaking initial assessments to render them safe.”

Pickup urged those affected to contact the SES for assistance.

Weatherzone said storms on Saturday were spawned by “oppressive humidity” which was experienced across much of NSW.

The excessive moisture triggered heavy rainfall and thunderstorms.

Moisture in the atmosphere is measured with the “dew point”.

Anything near 20 feels muggy to most people, and a dew point above 20 can “really start to feel uncomfortable,” according to Weatherzone.

“In New South Wales (on Saturday), dew points climbed to near or above 20 degrees across most of the state, apart from the Northern Tablelands and Snowy Mountains.

“In fact, dew points in the mid-20s were widespread from the Central West Slopes and Plains to the Sydney Metro.”
