Updated Severe Weather and Severe Thunderstorm Warning Service for WA and NT
Scheduled Date: 25 October 2016
The Bureau is improving the Severe Weather and Severe Thunderstorm Warning services for Western Australia and the Northern Territory. Previously, warnings for severe weather and severe thunderstorm events were described using text-only updates. The new service will include a graphical representation of the warnings to better convey which areas are at threat of severe weather or severe thunderstorms. This completes the national roll-out of graphical severe weather and severe thunderstorm warnings.

Cessation of stand-alone numerical weather prediction chart images in PNG format
Scheduled Date: 8 August 2016
As part of a transition to new chart generation technology, the Bureau of Meteorology will be ceasing stand-alone .png versions of numerical weather prediction charts delivered via FTP. The same charts will continue to be made available as .tar files via the same service.
Products affected are IDY20000-IDY20301 in .png format.

Updated Severe Weather Warning Service for VIC and TAS
Scheduled release: 28 July 2016
The Bureau is improving the Severe Weather Warning service for Victoria and Tasmania. Previously, warnings for severe weather events were described using text-only updates. The new service will include a graphical representation of the warning to better convey which areas are at threat of severe weather. Victoria and Tasmania will join South Australia, New South Wales and Queensland with the graphical severe weather warnings. Similar improvements to Western Australia and the Northern Territory are planned by the end of 2016.

Changes to UV Index forecast products
Scheduled Release Date: 21 July 2016
From 21 July 2016 the Bureau's UV Index forecasts are changing.
The 'UV Alert times' in routine weather forecasts will change to 'Sun protection times' in line with the Cancer Council's recommendation, for example "Sun protection 9:50 am to 4:10 pm, UV Index predicted to reach 10 [Very High]".
The UV Index forecast graphs will be replaced by a new service inside our forecast viewer 'MetEye' with daily maximum and 3 hourly maps of UV Index. This will replace the UV index graphs (bell curves).
Changes to manual observations on 28 April, 2016
Scheduled Release Date: 28 April 2016
Improvements in the Bureau of Meteorology's automated observation systems are delivering more frequent observations to rural and regional Australians. Many observations which were taken daily or once every three hours are now taken continuously, and the number of forecasts and other products will continue to increase once the Bureau's new supercomputer comes online in mid-2016, enhancing data analysis capabilities.
Due to advances in automated observations and improving technology, the Bureau undertook an internal review of its observations network and field offices around the country. Through this review, the Bureau identified duplication between manual and automated observations in several locations, as well as several types of observations which have few or no users. As part of improving its practices, the Bureau is ceasing manual recording of observations which are also taken by automated systems, and ceasing manual observations which have few or no users.
As a result, from Thursday 28 April staff at many Bureau of Meteorology field offices will move from shift work to day work, typically working standard office hours from Monday to Friday.
These changes do not affect the Bureau's forecasting and warnings services.
A list of manual observations ceasing due to minimal usage is available below.
Information for rural and regional Australia is available through the following Bureau services:
- Bureau of Meteorology Water and the Land pages provide an integrated suite of meteorological information for people involved in primary production, natural resource management, industry, trade and commerce.
- Users who require cloud cover information can access the Bureau's Himawari-8 Satellite Viewer for cloud images every 10 minutes right across Australia.
- The Bureau provides a range of solar products to help people wanting soalr energy information.
- Users of sunlight hours can access the Bureau's solar exposure product.
- MetEye™ delivers a high quality seven-day forecast service at six-kilometre intervals right across the country.
Specialist services for the aviation sector will continue.
Staff at field offices located at aerodromes will continue to provide manual observations input to Aviation Weather Reports while they are on duty.

West Takone radar upgrade

Service improvements to the West Takone, Tasmania, weather watch radar are complete and new operational changes commenced from 5 April 2016.
More detail on the West Takone radar upgrade.
Decommissioning of MTSAT satellite
Scheduled Release Date: 24 March 2016
In 2015 the Japanese Meteorological Agency (JMA) launched its new Himawari-8 geostationary satellite. This new satellite delivers high-resolution weather imagery for the Australian domain every ten minutes. Images from Himawari-8 can be viewed through the Bureau's high-definition satellite viewer.
As a result, the JMA is decommissioning their previous geostationary satellite, MTSAT, on 24 March 2016.
Bureau of Meteorology images generated from MTSAT will cease on this date, though images supporting the Bureau's low-definition satellite viewer will continue, utilising Himawari-8 data.
