SA Severe Weather Warning: 100km/h Winds, Heavy Rain and Flood Risk
SA Severe Weather Warning: 100km/h Winds, Heavy Rain and Flood Risk
SA Severe Weather Warning: A powerful winter storm is heading towards South Australia, bringing damaging winds, heavy rain, dangerous seas and ongoing flood concerns. The Bureau of Meteorology has issued several warnings covering large parts of the state.
Forecasters expect the worst conditions on Monday and Tuesday. Some coastal areas could see wind gusts of up to 100km/h, while parts of the Adelaide Hills, Kangaroo Island and the South East may receive up to 60mm of rain.
The warnings come as winter begins and while some inland communities continue to deal with flooding from earlier rainfall events.
Weather Snapshot
Damaging Winds: Up to 100km/h
Rainfall: Up to 60mm in some districts
Adelaide Rainfall: Up to 40mm across Monday and Tuesday
Marine Conditions: Strong Wind and Gale Warnings
Flood Risk: Inland flood warnings remain active
Peak Impact: Monday and Tuesday
SA Severe Weather Warning for Damaging Winds
The Bureau of Meteorology expects damaging winds to develop across western and central South Australia from Monday morning. The strongest winds will reach coastal districts and elevated areas later in the day.
The Bureau forecasts wind gusts of up to 100km/h across the West Coast, Eyre Peninsula and Yorke Peninsula on Monday afternoon and evening.
Western and central districts could experience gusts of up to 90km/h. The Mount Lofty Ranges may also see damaging winds during the afternoon.
Meteorologist Michael Conway said a deep low-pressure system moving across southern Australia will drive the severe weather.
Residents should secure loose outdoor items, park vehicles away from trees and stay indoors during the strongest winds.
SA Severe Weather Warning Brings Heavy Rainfall Risk
The storm system will also bring widespread rain to southern parts of the state.
Forecasters expect the heaviest falls across the Mount Lofty Ranges, Kangaroo Island and the South East. Some areas could receive up to 60mm of rain between Monday and Tuesday.
Adelaide could receive up to 15mm on Monday and another 25mm on Tuesday.
Showers are likely to continue through much of the week. Cooler temperatures will accompany the wet weather as winter settles across South Australia.
The Bureau is also watching for thunderstorms in the South East on Monday evening. These storms could bring heavier rain and stronger wind gusts.
SA Severe Weather Warning Issued for Coastal Waters
The Bureau has also issued Marine Wind Warnings for several South Australian coastal waters.
Strong winds and rough seas are expected across Gulf St Vincent, Spencer Gulf, Investigator Strait, Adelaide Metropolitan Waters and parts of the state’s western and southeastern coastline.
Boaters should closely monitor weather updates and reconsider plans during the peak of the storm.
Large waves, rough seas and poor visibility could create dangerous conditions on the water and along exposed coastlines.
Abnormally High Tides and Coastal Impacts Possible
Forecasters are also watching for elevated sea levels and abnormally high tides.
Strong onshore winds may push additional water against sections of the South Australian coastline. This could cause minor coastal flooding in low-lying areas.
Similar weather conditions affected several coastal communities during winter last year.
The Bureau may issue additional warnings if the risk of coastal impacts increases.
Inland Flood Warning Remains Active Across South Australia
Flood warnings remain active across parts of inland South Australia.
Several river systems continue to carry elevated flows from earlier rainfall events. Extra rain from this week’s storm could slow recovery efforts and prolong flooding in some regions.
Authorities remind motorists never to drive through floodwaters. Drivers should also check local road conditions before travelling through affected areas.
Some remote roads and access tracks may remain closed for an extended period.
Councils and Emergency Services Preparing
Local councils have already started preparing for the severe weather.
Holdfast Bay Council says crews are focusing on known stormwater hotspots and priority drainage areas. The council has also postponed some planned roadworks to protect public safety and infrastructure.
Emergency services are encouraging residents to prepare their properties now, especially in areas exposed to strong winds, rough coastal conditions or localised flooding.
How South Australians Can Prepare
The Bureau of Meteorology and emergency services recommend residents:
- Secure outdoor furniture, trampolines and loose items.
- Move vehicles under cover where possible.
- Stay indoors and away from windows during severe weather.
- Avoid unnecessary travel during damaging wind conditions.
- Keep mobile phones and essential devices charged.
- Monitor official weather warnings and emergency information.
- Never drive through floodwaters.
Official Weather Warnings
Residents can stay up to date using the following official resources:
- Bureau of Meteorology Severe Weather Warning
- Bureau of Meteorology Marine Wind Warning
- Bureau of Meteorology Inland Flood Warning
