Severe thunderstorms brought damaging winds and large hailstones to Adelaide, leaving fallen trees, blocked roads and damaged vehicles across metropolitan areas, according to emergency-service reports published on Monday, 12 October 2026.

South Australia's State Emergency Service (SES) received more than 100 calls for assistance after storms moved across the region on Sunday afternoon and evening. Approximately 80 per cent of the reported incidents involved fallen trees, highlighting the impact of strong winds on residential streets and surrounding properties.

Several suburbs in Adelaide's north and north-east experienced significant disruption. Reports of fallen trees came from areas stretching from Payneham towards Paradise, while other communities also dealt with hail and wind damage.

One incident affected Vale Park resident Niall Dowdell, who had returned home after visiting the Barossa region to celebrate his wedding anniversary. As the storm approached, he heard thunder followed by heavy rain. Within minutes, he discovered that a large tree had fallen onto the front of his car.

The incident illustrates how quickly conditions can deteriorate during severe thunderstorms. Trees weakened by strong winds or struck by lightning can fall onto vehicles, houses and roads, creating dangerous situations for residents and motorists.

Hail was another notable feature of the storm. The SES reported hailstones measuring approximately three centimetres across at Happy Valley at around 7:45 pm on Sunday. Such hail can damage vehicle panels, break windows and harm gardens and outdoor property. Storms crossed metropolitan Adelaide and other parts of South Australia throughout Sunday afternoon. Most of the activity had cleared by approximately 9 pm, although emergency crews continued responding to reports of damage.

SES duty officer Ian Bonython said the majority of call-outs were concentrated in Adelaide's northern areas. Fallen trees were also reported across several north-eastern suburbs, creating obstacles for residents and road users.

The Bureau of Meteorology warned that unsettled conditions would continue across South Australia on Monday. Forecasters expected showers, extensive cloud cover and further thunderstorms, with activity gradually shifting towards the state's north-eastern areas.

Residents were advised to remain alert to changing weather conditions and follow official warnings. During thunderstorms, people should seek shelter indoors, stay away from windows and avoid standing beneath trees. Drivers should never attempt to cross roads blocked by fallen trees or electrical hazards.

Anyone who encounters a fallen powerline should keep well away and contact the relevant emergency or electricity authority. Residents should also check their properties for storm damage only when conditions are safe.

The latest storm damage highlights the importance of preparation during South Australia's spring storm season. Securing loose outdoor objects, parking vehicles away from large trees where possible and monitoring official forecasts can reduce risks when severe weather approaches.

Emergency services continue to encourage residents to report dangerous situations and follow safety advice while storm activity remains possible.
