ADELAIDE (Azat TV) – Adelaide is bracing for what is expected to be its wettest weekend in months, with the Bureau of Meteorology (BoM) forecasting significant rainfall and severe thunderstorms across South Australia. The deluge, projected to begin intensifying on Saturday, February 28, 2026, and reach its peak by Sunday night, follows an unusually dry period for the region, raising concerns over flash flooding and hazardous conditions.
According to the BoM’s latest severe weather update on Friday, February 27, heavy rain and flooding are set to expand deeper into South Australia and Victoria. Southern and central parts of South Australia could see between 20 to 150mm of rain, with Adelaide specifically projected to receive between 50 to 150mm as the new week begins. Weatherzone reports a slightly more conservative forecast for Adelaide itself, estimating 7mm to 30mm on Saturday and 10mm to 50mm on Sunday, highlighting a degree of uncertainty in the exact precipitation totals for the metropolitan area.
A Severe Weather Warning for heavy rainfall, initially issued for central Australia, has been expanded to cover the southern coast of South Australia. Northern parts of the warning area could experience six-hourly rainfall totals up to 110mm, significantly increasing the risk of flash flooding. As the low-pressure system moves across the country, showers and storms are expected to build along the southern coastline throughout Saturday. Sunday night is identified as the main risk period for Adelaide and south-eastern South Australia, with the potential for flash flooding to develop across the city into Monday morning.
Adelaide’s Dry Spell Ends with Major Rainfall
The anticipated rainfall marks a stark contrast to Adelaide’s recent weather patterns. So far in 2026, the city has recorded a mere 3.6mm of rainfall, all of which occurred in February after a completely dry January. December 2025 also saw very little rain, with just 2.8mm, bringing the total for summer 2025-2026 to a meager 6.4mm. While the incoming rain will be welcomed by some parts of the south-east, particularly in western Victoria and south-eastern South Australia, it also presents challenges, including the risk of topsoil erosion and widespread generalized flooding.
Thunderstorm Risk and Travel Warnings
In addition to heavy rain, severe thunderstorms are forecast due to abundant tropical moisture across southern Australia. These storms are expected to bring heavy rainfall and are possible across central parts of the country, dipping into South Australia and southern Victoria. Adelaide falls within the severe thunderstorm risk area, especially on Sunday. The BoM has also issued multiple flood watches and warnings covering central and southern South Australia, urging residents to check conditions before travelling.
Impacts and Public Safety Directives
The heavy rainfall and potential flooding could create dangerous travel and driving conditions, with several roads and freight lines already impacted in central Australia. Authorities are advising the public to exercise extreme caution, obey all road signs, and never attempt to drive, walk, swim, or play in floodwaters. The dynamic nature of the weather warning suggests that conditions could change rapidly, and residents should stay updated through official channels.
The significant and unseasonal rainfall for Adelaide, following a prolonged dry spell, underscores the increasing volatility of weather patterns and the critical need for robust urban infrastructure to manage sudden deluges and protect public safety.
