During the period of 9 to 14 January 2015 at least two major rainfall events unfolded across a significant portion of South Eastern Australia. In general this event swept south east during the period which has resulted in a number of weather phenomena being recorded.
This event has had many positives but also some negatives including:-
- The bush fire crises was eased in Victoria and South Australia.
- A flash flood or flood event occurred at Bendigo following a single rain event.
- Many areas have exceeded their normal January average rainfall.
As part of this system that swept through on Friday 9/1/2015, thunderstorms developed across parts of Western Sydney producing an isolated fall of 66 mm at Blacktown Dog Pound. This storm also affected power supplies across the Blacktown area.
On Saturday evening, a heavy rainstorm again swept through parts of Sydney producing another 30 mm deluge over Blacktown.
Thunderstorms and heavy rain events during the period boosted rainfall totals in some areas such as 167 mm at Fowlers Gap in far Western New South Wales (This is a cumulative figure for the week ending 12/1/2015). Other strong readings of 149.2 mm was recorded at Berridale and 117.6 mm at Tumbarumba Post Office.
For the week ending 12/1/2015, the most significant rainfall fell in an area near and west of Alice Springs of Central Australia. In this regard, rainfall totals exceeded 200 mm and approached 300 mm for the region. Another area in North West Western Australia also received similar but substantial totals.
Rainfall covered most of New South Wales except the northern inland in areas such as Narrabri and Moree. In South East Australia and primarily in New South Wales, an area south and east of Canberra received cumulative totals of between 50 and 100 mm and smaller areas received higher cumulative total of 100 to 150 mm.
In western New South Wales, large areas received falls of 50 to 100 mm.
Even in Victoria, good falls have occurred across large areas of the state.
It is also identified that an area around Hobart in South East Tasmania received a drenching during the latter part of the period including 153 mm at Mt Wellington.
I have produced a number of plots and tables demonstrating where rainfalls occurred. I have produced individual tables for a number of events which builds an overview of which region received what, especially across New South Wales. I also include the Southern New South Wales event of the afternoon of the 13/1/2015 and the South East Tasmania event around Hobart.
