EARLY-LOOK SPRING FORECAST NOW AVAILABLE
PUBLISHED 18 AUGUST, 2017

The first outlook for spring gives a roughly equal chance for a wetter or drier than average season across Victoria. The major climate drivers for spring rainfall in Victoria, the El Niño-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), are both neutral and are likely to stay that way for the rest of 2017. But while there is no strong push towards more or less rainfall than normal, Victorian temperatures are very likely to be warmer than average. The outlook shows a similar pattern for both maximum and minimum temperatures, with the strongest odds (greater than 80% chance) for warmer than normal temperatures over the east, easing to the west (60-65% chance). Warmer than average sea surface temperatures surrounding southeast Australia are having the main influence on this outlook.




The spring outlook issued on 17 August is our first mid-month climate outlook. The mid-month outlooks provide more lead-time for those making climate-sensitive decisions. We'll continue to release an outlook at the end of the month and like daily weather forecasts where the forecast we issue for tomorrow has the greatest reliability, the end-of-month outlook will provide the clearest picture of likely temperature and rainfall for the months and season ahead. More frequent updates to our climate outlooks allows our climate model to take account of changes in the oceans and atmosphere sooner, and therefore provides better rainfall and temperature guidance. The spring outlook maps will be updated on 31 August.

Upgrades to the Bureau’s Climate Outlooks service are delivered as part of a four year Agricultural Competitiveness White Paper project, known as the Improved Seasonal Forecasting Service Project.

 


 

MELBOURNE LAVERTON RADAR UPGRADE
PUBLISHED 18 AUGUST, 2017

Melbourne's Laverton radar will undergo a mid-life upgrade, extending its operating life by a further ten years.  To achieve this, the Laverton radar will be offline from the 25 August to early October.
 
The upgrade will improve forecasters ability to 'see' weather coming, especially hail, rain, snow and even bushfire debris.
 
Currently, the radar sends out a horizontal pulse, identifying rain, but it can't differentiate between rain, snow or hail. The upgrade will provide forecasters with a more detailed picture by sending out both horizontal and vertical pulses. This allows forecasters to measure the size and shape of the object, so they will know if rain, snow or hail is heading our way.
 
During the upgrade, forecasters will continue to draw on observations from a range of sources including satellites, lightning detectors, automatic weather stations, flood warning networks as well as nearby radar at Broadmeadows.
 
While the Laverton radar is offline, Victorians can use the Broadmeadows radar as an alternative. 
 
We are asking everyone to be patient while this upgrade is underway, it's an important step for BOM to continually improve services to the public.

METEYE 
PUBLISHED 18 AUGUST, 2017

Another tool available to the public is MetEye.

This provides information on a map about current weather, rainfall, wind, waves, temperature, humidity and a UV index forecast.

MetEye also provides significant weather forecasts for thunderstorms, snow, rain, fog and frost.

Additionally, there's also satellite imagery from Himawari-8.

This technology scans Australia every 10 minutes and users can zoom into an area for a closer look.

Mapping groundwater-dependent ecosystems
PUBLISHED 21 July, 2017

Groundwater is an essential water source for many rural communities and agricultural areas, but did you know groundwater may also be sustaining your local surface water supply?

Many rivers, landscapes, plants and animals need groundwater to support their health in dry times—or all of the time. These are known as groundwater-dependent ecosystems. Being dependent on an underground, ‘hidden’ water source, means these ecosystems can be vulnerable. So why do they matter and how can they be protected?

Groundwater-dependent ecosystems can have ecological, social and cultural values, as well as significant economic value. Many agricultural activities depend on water supplied by rivers, which in turn can depend on inflows from groundwater, especially during dry periods. Managing our groundwater resources needs a balanced approach, ensuring the current and future needs of all users of the resource are taken into account.

The Groundwater Dependent Ecosystems Atlas is a national dataset and web-based mapping application to inform groundwater management and planning. You can visualise, analyse and download information about groundwater-dependent ecosystems in your area without needing specialised software.

 Find out more about this groundwater mapping tool, and access it and other groundwater resources through the Bureau of Meteorology's groundwater information suite.

WATER STORAGE APP AND WATER INFORMATION DASHBOARDS
PUBLISHED 21 JULY, 2017

There are now simpler ways to access water storage and water markets information around the country.

 The Bureau of Meteorology's water information dashboards give you access to water storage and water markets information via a single web page.

 They've also upgraded the BOM Water Storage smartphone application—first released in 2010—and it is now available for iPhone and Android users.

 The water storage dashboard and smartphone application continue to provide nationally consistent and directly comparable information surface water stores across Australia, giving you an independent and transparent understanding of the nation's water resources. The upgraded website provides improved search functions, and interactive graphs.

 The water markets dashboard supports more efficient water markets, with improved public access to information that supports trading decisions. This dashboard replaces the former National Water Markets website. Users continue to have access to existing water trade information—but now have access to a longer record and better quality data.

 The water markets dashboard also provides greater spatial resolution and trade information. This includes the ability to see water trades in more than 1000 regions across Australia.
