SES personnel were called to four incidents in Wagga on Monday night, with flash flooding in Forge Street, and reports of damage to roofs on three homes in the city.

A further eight calls for assistance were received in the Junee and Temora areas, where dozens of rural properties were still without power hours after storms ripped through.

Ben Pickup from the SES’s Murrumbidgee zone, said floodwaters up to a metre deep affected a 400-metre section of Forge Street.

With Wagga bracing itself for a second thunderstorm on Tuesday afternoon, Mr Pickup was warning people about the dangers of flash flooding.

“People should never ride, drive or walks through floodwaters, particularly flash flooding,” Mr Pickup said.

The Bureau of Meteorology  is predicting an 80 per cent chance of showers in the Riverina’s east and medium in the rest of the region on Tuesday afternoon, with the chance of a possibly severe thunderstorm.

The BoM recorded 28.4mm of rain at its Forest Hill base, but other parts of Wagga – and the wider region – received much less.

It warned on Monday there could be damaging winds, hail and heavy rainfall across NSW, most likely in the afternoon or evening on Tuesday.

This storm, along with strong winds, thunder and lightning, hit central Wagga just before 2.30pm.

Old Junee farmer John Baxter recorded 70mm of rain on his property, where winds ripped off the entire roof of one shed and half of another roof.

Mr Baxter’s wife Jan suffered a broken arm after she slipped while helping her husband to secure shed doors, but a trip to the emergency room was delayed by hours because her husband had to clear a path on the road through fallen tree branches.

The storm hit Mr Baxter’s property late on Monday afternoon.

“It was pretty horrendous,” Mr Baxter said.

“I was driving along and couldn’t find the farm gate. The rain was so heavy, I couldn’t see it.”

The storms were also extremely patchy. While a neighbour of Mr Baxter recorded 60mm of rain, only 15mm of rain was recorded on son Mark’s property, which is just a few minutes’ drive from his parents’ farm.

Monday night’s storms triggered blackout that affected thousands of homes across the region.

Essential Energy crews were called out to power outages affecting more than 5300 customers in West Wyalong, Ariah Park, Ardlethan, Temora, Young, Cootamundra and Junee.

Acting regional manager southern, Mathew Rogers said crews were kept busy well into the night responding to a range of incidents caused by severe storm activity in the area.

“Around 4460 customers in West Wyalong and Ardlethan were affected by a power outage with other outages affecting customers in the Ariah Park, Temora, Young, Cootamundra and Junee areas,” Mr Rogers said on Monday afternoon.

“Supply has progressively been restored to most customers this morning, however, 55 customers still remain without supply. Crews will continue to work on repairing damage to the network.”
