The Bureau of Meteorology advise that a Severe Thunderstorm could impact on the Northern suburbs of Canberra over the next hour.
Storm water drains could carry large volumes of water and ACTSES and ACT Fire & Rescue advise the public to avoid the fast flowing water around those possible areas.
Road conditions could also deteriorate.
Due to possible lightning strikes, residents are advised to stay indoors.
Residents who require storm and flood assistance can call the ACTSES on 132-500.
