What does a severe weather warning mean for NSW?
The Bureau of Meteorology issues these warnings for thunderstorms, east coast lows or other systems that produce hazardous conditions. A typical warning covers damaging wind gusts exceeding 90 km/h, flash flooding from intense rainfall, and large hail. Treat it as an instruction to move to shelter and avoid travel until the system passes.
