“At least the sun came up today,” he said.

“Today is a great cleanup day.”

The Southland District Council had listed the road closures on social media and said the roads around western Southland around Riverton and Otautau had temporary speed limits in place and can be navigated with care Monday morning. Some roads were also affected in the Gore district on Sunday.

McKay said that the Civil Defense had contacted everyone who suffered property damage in the floods. Some properties in Riverton, Invercargill and Otatara were pumped by fire crews, and a dozen homes on Grant Rd in Otatara had water up to the front step, he said.

The Rural Support Trust met Monday morning to plan how to reach farmers in the eastern south who had been affected by the floods.

The Wyndham and Mokoreta areas had been badly affected on Sunday, although locals had coped well with the situation, he said.

“There has just been a lot of surface water. It didn’t go down the river systems as it usually does, the ground was just saturated from the weather earlier in the week so it didn’t run off.

A polar explosion on Monday and Tuesday of last week brought snow to low levels in the province.

Around 50-60mm of rain fell over 24 hours in some areas over the weekend.

“It never got to the level where we would get warnings from the MetService. It was a constant rain. ”

As of Monday morning, Environment Southland still had flood warnings issued for the lower reaches of the Mataura, Mokoreta, Makarewa, Waiau and Waihopai rivers, Hedgehope Stream and Waituna Creek, although levels were dropping.

At Riverton on Taramea Bay Rd, owner Cherly Murphy said she had seen many heavy rains in the area before, but none had been as bad as Sunday.

Although there was no damage to his property, a small stream running through his backyard flooded over the banks and turned it into a lake, Murphy said.

“It was a lot of water.”

The monitor that measures water levels had broken, causing sewage to be pumped overhead, Duncan said.

It was fortunate that the high tide had been at 4 p.m. when the rain had subsided or the damage could be worse, Duncan said.

According to MetService, more rain was forecast for Southland on Tuesday and Wednesday, while strong winds were expected to continue.
