Service Announcements - 2017 Archive

  • Updates to Water and the Land forecast wind maps:

    Scheduled Release Date: 18 December 2017

    The Water and the Land forecast wind maps will be updated with changes to arrow style and the location of the legend. Days 3 to 7 will use the ACCESS model instead of the model from the European Centre for Medium-Range Weather Forecasts.

  • Changes to rainfall forecast details in 7-day forecasts and Coastal and Local Waters forecasts:

    Scheduled Release Date: During week commencing 11 December 2017*

    In response to feedback, the Bureau is changing its rainfall forecast services to make them easier to understand and more representative of the day ahead:

    • 'Possible rainfall' amounts of 0 mm will no longer be shown in forecasts when the 'Chance of any rain' is less than 25% for the day.
    • The icon graphic, which appears in forecasts for major cities and towns for the next 7 days, will show rain or showers when the 'Chance of any rain' is 35% or higher for the day. The short-form (précis) text will use the same threshold (35% or higher) for reporting rain or showers. Previously the threshold was 25%. No changes will occur to the reporting thresholds for other phenomena (such as thunderstorms).
    • The chance of rain or showers (%) will only be shown in marine forecasts (Coastal and Local Waters areas) when it is 50% or higher for the day, in that coastal zone.
    * Release timing is subject to technical and operational requirements at the time.
  • Updated high seas forecast and ocean wind warning boundaries:

    Scheduled Release Date: 13 December 2017

    From mid-December 2017, the Bureau of Meteorology's north-east and south-east forecast and warning area boundaries will change to align with the service boundaries of the New Zealand MetService. Both agencies have agreed to remove the overlap of their services across the Tasman Sea. Mariners will be able to refer to adjacent forecasts and warnings as they cross the Tasman Sea. The high seas forecast and warning service boundaries will now align with each country's METAREA boundaries, designated by the World Meteorological Organization, under the Global Maritime Distress and Safety System.

    Mariners do not need to change how they receive high seas weather information. High seas forecasts and warnings will continue to be provided on the same HF radio schedule, and on the satellite SafetyNET system. There are no changes to tropical cyclone warning areas or services.

    For maps of the high seas forecast and warning areas visit http://www.bom.gov.au/marine/high-seas.shtml.

  • Updated Severe Thunderstorm Warning Service for Hobart:

    Scheduled Release Date: 7 December 2017

    The Bureau is improving the Severe Thunderstorm Warning services for Hobart. The new service will include a graphical representation of the Immediate Threat area from individual severe thunderstorms with their forecast movement for the next hour. This service is now consistent with detailed severe thunderstorm warnings issued for all capital cities.

  • Updated Severe Thunderstorm Warning Service for Perth:

    Scheduled Release Date: 5 December 2017

    The Bureau is improving the Severe Thunderstorm Warning services for Perth.

  • New webpage 'Our Performance: Bureau Forecast Accuracy'

    Scheduled Release Date: November 2017

    The Bureau has published a summary of performance statistics for the 2016–17 period. It presents an analysis of the accuracy of temperature and rainfall forecasts over recent years and a snapshot of performance for wind and tropical cyclone intensities.

  • Radar upgrade complete

    Scheduled Release Date: October 2017

    The Bureau of Meteorology has completed the upgrade of four radars in Adelaide, Brisbane, Melbourne and Sydney. Between June and October 2017, each radar was taken offline for three to six weeks to add new Dual Pol technology. This technology adds a vertical pulse to the current standard horizontal pulse and helps forecasters to more clearly distinguish between rain, hail, snow or ice pellets.

  • Implementing improvements to the Bureau's national Flood Watch service

    Scheduled Release Date: Throughout October 2017

    The Bureau of Meteorology will be introducing some changes to the Flood Watch service to deliver graphical products, have consistent language and common structure across Australia. The trigger for this work was the ANZEMC's Standardisation of Bureau of Meteorology Hazard Services Taskforce recommendation for the Bureau to deliver nationally consistent flood warnings and watches. The Bureau has used this opportunity to introduce new output formats and GIS information layers. These changes will improve the clarity of flood watches, and better integrate with emergency services. The improvements are expected to be released in all regions during October 2017.

  • Extending the Fire Danger Ratings forecast

    Scheduled Release Date: 21 September 2017

    Fire Danger Ratings are used by Emergency Services and the Bureau to communicate the level of bushfire risk. In conjunction with Emergency Services, fire danger ratings are now available for the next four days during fire danger season in each state and territory. The extension to four days means that people can keep informed of the ongoing level of bushfire risk in their area and plan ahead to stay safe. More information about Fire Danger Ratings is available at www.bom.gov.au/weather-services/bushfire/

  • Radar upgrade – Update

    Scheduled Release Date: 17 August 2017*

    The Bureau of Meteorology is upgrading and extending the operating life of four radars (in Adelaide, Brisbane, Melbourne and Sydney) in 2017. Each radar will be offline for approximately six weeks.

    The upgrade for Adelaide was completed on 9 June. The remaining radars will be offline through August - October 2017. The table below sets out the planned outages and nearby radars that will be available during the outage:

    City Radar Scheduled Outage Alternative Radar

  • Adelaide's official weather forecast now at the city centre

    Scheduled Release Date: 3 August 2017

    The Bureau of Meteorology's official weather forecast location for Adelaide will be relocated from Kent Town to the City Centre. This is in response to the Adelaide official observation station move in June 2017. The official name of the new station will remain Adelaide.

  • Marine wind forecast maps updated

    Scheduled Release Date: July 2017

    The Marine Wind Forecast maps have been updated with changes to arrow style and the location of the legend. Days 3 to 7 now use the ACCESS model instead of the model from the European Centre for Medium-Range Weather Forecasts.

  • Changes to frost reporting in forecasts

    Scheduled Release Date: 31 July 2017*

    In response to customer feedback, the Bureau has revised how frost is reported in forecasts. From 31 July 2017*, frost (if forecast) may appear in the short form (précis) and long form forecast for all seven days. The frost daily weather icon will no longer appear, giving users a more representative icon for the day's weather.

    *Subject to operational requirements at the time.

  • Update to state-based observations summary rainfall data

    Scheduled Release Date: 17 July 2017

    The State and Capital City observations summary data (XML data files) is being updated to remove the reporting of the word 'Trace' for the Rain elements. A rainfall observation that is less than 0.2mm, but greater than zero, will now be reported as 0.1mm.

  • Automatic Weather Station at Point Avoid, Coffin Bay National Park, SA

    Scheduled Release Date: 14 July 2017

    Following the decommissioning of Coles Point automatic weather station, the Bureau relocated to a new site at Point Avoid, within the Coffin Bay National Park. The new site gives an improved exposure for the instruments and will provide forecasters better observations of weather systems coming across the Great Australian Bight.

    To view observations from Point Avoid, go to the South Australian latest weather observations.

  • Lightning Observation Service

    Scheduled Release Date: 27 June 2017

    The Bureau of Meteorology has developed a lightning detection service which is now available through the Bureau's Himawari-8 satellite image viewer (http://satview.bom.gov.au/).

    This service allows users to view lightning observations across all of Australia including areas outside of radar coverage. Lightning observations corresponding to frequency of strikes in a 10 minute period are displayed, and can be selected by clicking on the "Layers" feature of the satellite viewer.

  • Hazardous Surf Warning (NSW & QLD only)

    Scheduled Release Date: 30 June 2017

    In NSW and southern QLD coastal waters a Hazardous Surf Warning will be available when hazardous surf conditions are present. This new warning alerts the community when the surf may appear gentle, but can still be hazardous for activities such as swimming, rock fishing and boating. Caution statements will continue to be included in the relevant NSW and QLD forecasts when hazardous surf conditions are expected to occur.

    See the latest warnings on the Australian warnings webpage.

  • Adelaide's official weather observation station is returning to its original location

    Scheduled Release Date: 14 June 2017

    The Bureau of Meteorology's weather observation station at West Terrace will replace the Kent Town station as Adelaide's official weather observation location on 14 June 2017.

    The new station was commissioned in early 2017 and will provide upgraded weather observations including wind, rainfall and temperature. The move has occurred due to the increasing effects of urbanisation at the Kent Town site. The official name of the new station will be Adelaide (West Terrace / ngayirdapira).

    See further details of this change.

  • Falls Creek forecast extended

    Scheduled Release Date: 9 June 2017

    The Bureau of Meteorology will produce a Town Forecast for Falls Creek from the start of the 2017 snow season. Town forecasts are available for major and tourist centres and include a longer text forecast out to seven days. The forecast will provide more detailed information including the forecast for wind and other phenomena (such as snow) over the next seven days.

    See the extended Falls Creek forecast on the Australian Alps Weather webpage.

  • Decommissioning of Coles Point, SA Automatic Weather Station

    Scheduled Release Date: 23 May 2017

    This station ceased reporting from 23 May 2017. The site lease expires on 31 May 2017 so the Bureau has taken this opportunity to relocate to a new site 33km south on Point Avoid in the Coffin Bay National Park. The new site affords an improved exposure for the instruments and will provide forecasters earlier surface observations of weather systems transitioning across the Bight. The new Automatic Weather Station is expected to come online mid June 2017.

  • Changes to the update time for UV Index forecast products

    Scheduled Release Date: 23 May 2017

    From 23 May 2017 the Bureau’s UV Index forecasts will be updated only once per day (instead of twice). The UV forecasts and Sun Protection Times will therefore update once per day at around 9 pm AEST / 7 pm AWST.

  • Radar upgrade

    Scheduled Release Date: 10 April 2017*

    The Bureau of Meteorology is upgrading and extending the operating life of four radars (in Adelaide, Brisbane, Melbourne and Sydney) in 2017; each radar will be offline for approximately six weeks.
