Thunderstorms have kept emergency crews in South Australia busy overnight, with power cut to more than 4,000 homes as severe weather and lightning passed across the state.
Many of those homes were in the state's south-east, close to the Victorian border where the weather is expected to be considerably worse.
Lightning killed three horses and injured another at a horse refuge north of Mount Gambier.
Lynn Brierley runs the refuge and said she was less than two metres from the horses when the lightning hit.
"It just sounded like gunshot going off in my ears and there was a great big white ball, the size of a soccer ball," she said.
"Next thing I know all three horses that were in front of me just dropped to the ground dead."
Power has since been restored to most properties, but hundreds remain without power, including many in the state's north.
Ironically, some of the outages are near Jamestown, close to Tesla's new giant battery, which will be officially unveiled today and is designed to stop summer blackouts.
While the weather has not been as damaging as predicted, rainfall totals have reached about 25 millimetres in the Mount Lofty Ranges and Mid North.
"We've had some decent rainfall totals overnight and there is expected to be more today. There could be some local heavy falls around," Bureau of Meteorology senior forecaster Tom Boeck said.
"There have also been some severe wind gusts. Oodnadatta had a wind gust of 118 kilometres an hour before midnight.
"Most parts of the state had some thunderstorm activity."
Showers expected to clear in time for Test
The bureau said while rainfall totals could still reach 40 to 70 millimetres, the first day of the second Ashes Test was unlikely to be significantly affected.
"There's going to be a little bit of shower activity in the morning," senior forecaster Simon Timcke said.
"By the time the game starts on Saturday, there won't be many showers left."
The Adelaide Bite baseball team was forced to cancel last night's match because of the weather, while the State Emergency Service responded to about 60 callouts, mainly across Adelaide's metropolitan area.
"The majority of those requests for assistance have been for trees down and for impacts to property," state duty officer Milo Kuga said.
"We were anticipating that the weather would have brought some greater impacts, but fortunately the impact has been relatively minor."
Mr Kuga said there was still "considerable rainfall" for the rest of today.
Warnings remain in place, including a flood watch for various river catchments.
"The rainfall totals expected over Victoria are significantly higher than over South Australia," Mr Boeck said.
