If severe weather is forecast for NSW, expect significant delays and cancellations across roads, rail, ferries and flights. Plan extra travel time, check weather radar and official alerts, and consider postponing non-essential trips until conditions clear.
What types of transport disruptions happen during severe weather?
Heavy rain and flooding close highways and urban roads, often for hours. Flash flooding can trap vehicles and stop bus and train services. Strong winds ground some flights and may suspend harbour ferries. Landslips occasionally block rail lines in the Blue Mountains and South Coast.
Bureau of Meteorology severe weather warnings usually include expected impacts on transport. Check Hunter severe weather warnings if you travel through that region.
How can I stay up to date?
Before you travel, check the Australia weather hub for current warnings. Use Live Traffic NSW for real-time road closures. Transport for NSW posts disruption updates on its website and social media. Listen to local ABC radio for emergency broadcasts.
How long do rail closures usually last?
Rail closures depend on floodwater receding or debris clearance. Most last a few hours, but major events can shut lines for 12–24 hours. Check Transport for NSW before heading to the station.
Are all flights cancelled during severe storms?
Not always. Sydney Airport may suspend departures during lightning or strong crosswinds. Check your airline for individual flight status. Regional flights are more likely to be cancelled.
