Weather Hazards

Lightning thunderstorm storm weather hazard

The weather is one of the major risks to bushwalkers. Its effects can be widespread and catastrophic. Bushwalkers should always check weather forecasts before any trip to avoid becoming involved in an incident.National parks close for a variety of reasons including bushfire, hazard reduction burns, flooding, storm damage, pest control, infrastructure damage and bush regeneration. Check with NSW National Parks and Wildlife Service (NPWS) for park alerts or closures before you set out.It’s also a good idea to talk to local rangers to gain a clear picture of any safety issues in their local park. Find NPWS Visitor Centre phone numbers using the interactive map on the NSW Office of Environment and Heritage website.

Where can I find weather warnings?

The Australian Government Bureau of Meteorology posts nationwide rain radar, satellite images, weather  maps, tide predictions, sea temperature, tsunami  warnings and cyclone maps.

The new Bureau of Meteorology mobile weather website makes it easier and quicker to check Australia’s official weather forecasts. Access it from your mobile device on http://m.bom.gov.au/
