A Severe Weather Warning for heavy, locally intense rainfall has been issued for large parts of South Australia, with the risk expected to increase across central and southeastern districts, including Adelaide, on Sunday.
The warning, issued at 11:18am CDT on Saturday 28 February 2026, covers the Adelaide Metropolitan, Mount Lofty Ranges, Lower Eyre Peninsula, Eastern Eyre Peninsula, Yorke Peninsula, Flinders, Mid North, Kangaroo Island, Riverland, Murraylands, Upper South East, Lower South East, North East Pastoral and parts of the West Coast and North West Pastoral districts.
The Bureau of Meteorology says a low pressure system over southern parts of the Northern Territory is moving slowly southwards, expected to cross into north-central South Australia this afternoon and evening. An extremely humid tropical airmass is wrapping around the southern flank of the low, extending into central and southern parts of the state.
A trough over southern South Australia is forecast to interact with the tropical airmass into Sunday, increasing the likelihood of heavy and locally intense rainfall.
Heavy rainfall which may lead to flash flooding is likely about northern and western parts of the state today and possible about central and southeastern parts, including Adelaide. The risk is expected to increase across central and eastern districts, including Adelaide, on Sunday.
Six-hourly rainfall totals between 30 and 50mm are possible today, increasing to 40 to 60mm about central and southeastern parts on Sunday.
Locally intense rainfall which may lead to dangerous and life-threatening flash flooding is likely about northern and western parts today and possible in thunderstorms elsewhere. The risk will broaden to the Murraylands and Riverland districts tonight and more broadly about central and southeastern parts, including Adelaide, on Sunday.
