    To advise members of an upgrade to the Perth (Serpentine) radar, and an outage to this radar whilst upgrade works are completed.

    The issue

    • From 29 August 2022, the Bureau of Meteorology commenced the continuation of works at the existing Perth weather radar site.
    • The Serpentine weather radar, south of Perth, is being replaced with a new radar to provide the local community and industry with more reliable and up-to-date weather information.  
    • To complete the second phase of works to replace the radar, the existing radar will be offline for approximately 8 to 12 weeks. 
    • There will be no impact to the Bureau's forecasts and warnings, which are informed by observations from a range of assets including satellites, upper atmosphere monitoring and automatic weather stations.
    • During the outage period, those seeking situational awareness of rain can access radar data from the recently upgraded Perth Airport radar, as well as satellite images from the Himawari-8 satellite. Images that show cloud cover and lightning strikes are also available from the Bureau's website

    Purpose

    The Serpentine weather radar, south of Perth, is being replaced with a new radar to provide the local community and industry with more reliable and up-to-date weather information. To complete the second phase of works to replace the radar, the existing radar will be offline for approximately 8 to 12 weeks (late August to late November 2022).

    From 29 August 2022, the Bureau of Meteorology will continue works at the existing radar site. The old radar will be switched off at this time, to allow the new tower and radome to be installed.

    The replacement works are being done in two phases to minimise disruption to the community. The first phase of the project was completed in late-2021.

    The second phase of the project was originally scheduled to recommence in February 2022, however due to COVID-19 related border closures and travel restrictions, the Bureau rescheduled this work to take place outside of peak severe weather periods. Once complete, the community, emergency services and local industry will benefit from dual-polarised Doppler radar technology, one of the best tools for observing real-time rainfall and wind conditions across large areas.

    During the outage, there will be no impact to the Bureau's forecasts and warnings, which are informed by observations from a range of assets including satellites, upper atmosphere monitoring and automatic weather stations.

    The radar will need to be offline for technicians to complete the work. During the outage period, those seeking situational awareness of rain can use a range of alternative sources.

    • The recently upgraded Perth Airport radar will be available on the Bureau's website (bom.gov.au), this data will also be automatically visible on the BOM Weather app

    • The community can also access satellite images from the Himawari-8 satellite. These images are available from the Bureau's website and show cloud cover and lightning strikes.

    This radar replacement project is part of the Bureau's ongoing work to enhance and improve the Australian radar and observation network.

    The Perth (Serpentine) radar is one part of a comprehensive weather observation network of more than 11,000 assets including satellites, upper atmosphere monitoring, automatic weather stations, ocean buoys and flood warning networks.

    As a key stakeholder of the Bureau of Meteorology, we appreciate any support you can give to advise your colleagues or networks about this important change.
