Emergency services in New South Wales have been placed on alert due to threats of severe thunderstorms and heavy rainfall during the long weekend. The Bureau of Meteorology predicts a cold front will bring widespread thunderstorms to the South Coast, Illawarra, Sydney, Central West, and Riverina, with some areas potentially receiving up to 100mm of rain alongside damaging winds and large hail.

NSW SES Acting Assistant Commissioner Brigid Rice identified flash flooding as the primary concern, warning that conditions can change rapidly and make roads dangerous within minutes. Residents in Greater Sydney, the North Coast, and southern NSW have been urged to secure loose outdoor items, clean gutters, and avoid driving through floodwaters.
