Backyards have been turned into rivers in Adelaide today following the heaviest September rain in a century.
Three days of rain and thunderstorms have left parts of Adelaide and South Australia underwater this morning. A low pressure system moving over the state's southeast yesterday drove in the heaviest falls and damaging, capping off the multi-day drenching.
Parts of Adelaide received the heaviest rain in the state during the past 24 hours.
Millbrook on the Adelaide Hills saw 62mm in the 24 hours to 9am today, its heaviest September rain since at least 1914. Mount Lofty received 83mm in the same period, their heaviest September rain in over a century. This brings the three-day total at Mount Lofty to 120mm since Monday morning, more than a month's worth of rain.
Adelaide itself has seen 38mm since Monday morning, more than half the September average. The city is now having its wettest September in six years and is already having a wetter spring than 2015, 2014 and 2012.
Damaging winds also lashed the state on Wednesday, with Adelaide Airport registering a gust of 91km/h. These winds had no trouble bringing down trees with help from rain-softened soil.
Rain has now eased, although there are still areas of local flooding across the city and state today. A number of roads were closed this morning due to fallen trees and flooding, with a road weather alert in place for Adelaide due to hazardous driving conditions. Flood warnings are also in place for the Angas, Bremer and Onkaparinga Rivers and the Gawler River Catchment.
