  • Changes to sea surface temperature forecasts for Great Barrier Reef

    Scheduled Release Date:27 November 2018*

    The Bureau will be updating its seasonal sea surface temperature anomaly forecasts for the Great Barrier Reef. This follows the upgrade of the seasonal model from POAMA (Predictive Ocean Atmosphere Model for Australia) to ACCESS-S1 (the seasonal prediction version of the Australian Community Climate and Earth System Simulator). The new service will provide more accurate and higher resolution outlooks for the next six months, showing more detail for each management zone in the Great Barrier Reef.

  • Indian Ocean Tsunami Warning Status website launch

    Scheduled Release Date:3 September 2018*

    The Bureau as a Tsunami Service Provider(TSP) for the Indian Ocean Tsunami Warning & Mitigation System will launch on 3 September 2018 a new public website that displays the latest status of tsunami warnings in the Indian Ocean. It will be available at www.bom.gov.au/tsunami/iotwms and can be accessed via the existing web link of the tsunami warning system at www.bom.gov.au/tsunami. From the webpage, users can also access the official tsunami warning web site of an Indian Ocean country for more information, noting however not all countries have such website.

    The new website will assist Australians with relatives or friends in potentially tsunami-affected areas in the Indian Ocean to stay up to date with the latest information whenever there is a major undersea earthquake.

    It is important to point out that TSPAustralia does not issue tsunami warnings for other Indian Ocean countries. Rather, it provides tsunami threat information to all Indian Ocean National Tsunami Warning Centres (NTWCs) who then issue tsunami warnings to their respective communities as their sovereign rights.

    All warnings displayed on this page came directly from those NTWCs who reported their warning status to three TSPs of Australia, India, and Indonesia in the Indian Ocean.

  • Changes to the Ocean Forecast Map Viewer

    Scheduled Release Date:During week commencing 13 August 2018*

    The Bureau is improving its ocean forecast map viewer at http://www.bom.gov.au/oceanography/forecasts/

    Changes will include:

    • Increased number of map tiles for the larger states of Queensland and Western Australia.
    • A new map tile covering eastern Tasmania and Timor Sea area.
    • Currents will now show distance travelled in 12 hours providing more meaningful comparisons.

    The new map tiles mentioned above will greatly improve readability leading to better clarity in interpreting forecasts. Additional tiles will be released soon after this time providing detailed forecasts using zoomed in maps for specific areas of interest including capital cities.

    *Timing is subject to technical and operational requirements at the time.

  • Changes to the Latest Coastal Weather Observations webpages

    Scheduled Release Date:Week commencing 23 July 2018*

    The Bureau's 'Latest Coastal Weather Observation' webpages show observations from weather stations along the coastline, grouped by marine forecast zones. The most recent observation is shown on a summary page (for example, Latest Coastal Weather Observations for NSW: www.bom.gov.au/nsw/observations/coastal.shtml). Observations from the previous 72 hours for each station are shown on a history page (for example, Latest Coastal Weather Observations for Cape Byron: www.bom.gov.au/products/IDN60701/IDN60701.94599.shtml).

    Based on customer feedback, the Bureau is making the following changes to these pages to improve their use and consistency:

    • columns will be reordered so that similar elements are grouped together and the most relevant elements for mariners are at the beginning;
    • the column 'Pressure' will be shortened to 'Press hPa' to align with other observation pages; and
    • the 'Trend' column for pressure will be removed as data are unavailable.

    This change will not affect other formats (e.g. json and axf) or non-coastal observation pages.

  • Forecast wind wave heights for significant inland waters

    Scheduled Release Date:Week commencing 25 June 2018*

    Forecast wind wave heights will soon be available for Australia's significant inland waters.The aim is to raise awareness of wave conditions among users of lakes and other inland waters, reducing the likelihood of boats being swamped by waves.

    Forecast wind wave heights (in metres) will be available in three-hourly blocks, four days ahead. The maximum significant wave height is based on the maximum fetch from the 8-point compass of wind directions.

    The forecast data will be available to registered users in the Australian Digital Forecast Database (ADFD) and via the free online mapping tool MetEye.

    *Timing is subject to technical and operational requirements at the time.

  • Changes to the Interactive Weather and Wave Forecast Map Viewer

    Scheduled Release Date: Week commencing 28 May 2018*

    The Bureau is introducing additional areas for forecast maps in the Interactive Weather and Wave Forecast Map Viewer. All maps are produced from the Bureau's ACCESS model (for atmospheric elements) or AUSWAVE model (for ocean wave elements).

    The new areas are:

    • capital city local waters (ACCESS surface winds)
    • South Pacific (AUSWAVE elements)
    • Papua New Guinea (AUSWAVE and ACCESS elements)
    • Tasmania (ACCESS elements)—previously combined with Victoria.

    All areas in the Map Viewer will have the option of viewing a 7-day period based on the global ACCESS or AUSWAVE forecast models.

  • MarineLite service upgraded to include charts

    Scheduled Release Date: Week commencing 7 May 2018*

    The Bureau's MarineLite webpages are designed for mariners, such as those on cruising yachts and commercial vessels, whose offshore access is limited to satellite internet communication channels, or in areas of marginal mobile phone coverage. Previously these pages contained text-only forecasts and warnings, but this upgrade will include the provision of "lite" charts with small file sizes.

    The inclusion of "lite" charts enables users to be better informed, aiding decision making and situational awareness to improve safety outcomes.

  • Change to graphical forecast for thunderstorms in MetEye

    Scheduled Release Date: During week commencing 21 May 2018*

    In response to feedback, the Bureau is changing the 'Chance of' thunderstorms element within the thunderstorms graphical forecast in MetEye. The change will ensure this graphical forecast better represents the chance of thunderstorms in each three-hourly time-period and aligns with corresponding text forecasts(such as district forecasts). The thunderstorm forecast can be found under 'Storms, Snow, Fog, Frost…' in MetEye.

    *Timing is subject to technical and operational requirements at the time.

  • State and territory observation summary webpages to be updated every 10 minutes

    Scheduled Release Date: During week commencing 26 March 2018*

    The Bureau's 'Latest Weather Observation' webpages show observations from automatic weather station and manual stations, with the most recent observation shown on a summary page. Separate summary webpages are available for each state and territory (for example, the Latest Weather Observations for NSW at www.bom.gov.au/nsw/observations/nswall.shtml).

    To provide greater awareness of current conditions, state and territory summary pages will be updated every 10 minutes (rather than every 30 minutes).

    *Timing is subject to technical and operational requirements at the time.

  • Radar upgrade

    Scheduled Release Date: 14 March 2018*

    The Bureau of Meteorology will be conducting a major refurbishment of three radars (in Brisbane, Melbourne and Sydney) in 2018. Each radar will be offline for approximately 8 days.

    This refurbishment will replace ageing components, including the klystron, power supplies, motor and gear assemblies and control circuitry. This will complete the process started in June 2017 with the Dual Pol technology upgrade, and will extend the life of the radars by another 10 years.

    The radars will be offline through April 2018. The table below sets out the planned outages and nearby radars that will be available during the outage:

    City Radar Scheduled Outage Alternative Radar
    Melbourne Laverton Late April 2018* Broadmeadows (25 km northeast)
