Several small bushfires are burning in northwest South Australia after a barrage of lightning strikes overnight.
Lightning struck about 80,000 times across SA on Sunday night after a trough moved across the state, the Bureau of Meteorology says.
Firefighters are monitoring a blaze at Nectar Brook in the southern Flinders ranges, as well as several other small fires sparked by the lightning.
Thousands of homes lost power during the storm, and authorities were still working to restore power to almost 3000 homes at about 1pm (CST) on Monday.
The majority of the homes without power are located in Aldinga Beach and Port Willunga, about 40km south of Adelaide.
