OCTOBER 2017 - WARMER THAN NORMAL AND DRY IN THE SOUTH
pUBLISHED november 10, 2017

Across Victoria, October rainfall was generally average to below average but some areas around the Otways and West Gippsland were very much drier than usual (decile range 1—in the driest 10% of the historic record for October). Large parts of East Gippsland are suffering serious to severe rainfall deficiencies in their latest 6-month to 12-month rainfall totals. October lower-layer soil moisture (10 cm – 100 cm depth) was below average across most of State and very much below average in East Gippsland.

Both daytime and overnight temperatures were warmer than average. The mean monthly maximum temperature for the State was 2 °C warmer than average for October.



Warm northerly winds were responsible for a string of new overnight temperature records on 18 and 19 October, with many sites recording daily minimum temperatures more than 10 °C above their long-term monthly average.

La Niña a possibility but above average rainfall not favoured

While the El Niño-Southern Oscillation (ENSO) remains neutral, the Bureau's ENSO Outlook is currently at La Niña WATCH. The means the chance of La Niña developing in 2017 is around 50%, about twice the normal likelihood. If La Niña does develop, it’s likely to be short-lived and much weaker than the last La Niña event (2010 to 2012). It is unusual for La Niña to develop this late in the year, but not unprecedented. While La Niña typically means above average rainfall for Victoria, the November to January rainfall outlook does not favour above average rainfall. The outlook shows a roughly equal chance of a wetter or drier than average three months ahead. Cooler waters in the eastern Indian Ocean are driving a drying signal that is competing with the typical wetting influence from a possible La Niña in the tropical Pacific Ocean.

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.

NEW LIGHTNING VIEWER

The Bureau of Meteorology has released a 'cracking' new lightning viewer available at satview.bom.gov.au

This lightning detection service has been added as a viewing option or 'layer' for the Bureau’s high definition Himawari satellite cloud viewer and is updated every 10 minutes.

The Bureau's General Manager Data Dr Anthony Rea said the addition of a near real-time information lightning service can help people seek safety in advance of an approaching thunderstorm.

“Lightning is dangerous. It is associated with thunderstorms and can occur well away from the storm’s centre," Dr Rea said.

“Adding the new lightning layer to the satellite infrared cloud image will also help Australians living in remote areas with limited radar coverage to identify severe weather and track thunderstorms."

The Bureau’s viewer shows the frequency of lightning ranging from two to more than 20 strikes every ten minutes. It also shows the most recent four hours of lightning data consistent with the satellite cloud image updates.

The lightning coverage is Australia-wide and extends into the surrounding high seas.

Users can zoom into to an area only slightly bigger than that of New South Wales. They can also select viewing options that add coastal and state boundaries, as well as roads and cities, to show where lightning has struck.
