June drenching brings welcome relief

The Bureau of Meteorology announced today that heavy, and in some cases record June rainfall over eastern and southern coastal Australia, has largely removed serious to severe rainfall deficiencies that had developed during 2005. Most of the northern two-thirds of New South Wales and the southern half of Queensland recorded more than twice the long-term June average, with large areas having had more than four times the monthly average. It must be remembered though, that the climate is naturally rather dry in June over western NSW and Queensland, with monthly means below 25 mm in many instances.

However, despite the recent heavy rains, rainfall deficits extending back over three years and longer (affecting water storages and stream flows in particular) still remain across large parts of eastern Australia. Some areas missed out on significant June rainfall, most notably southern Victoria, northern Tasmania and parts of northwestern and central Australia.

4-month rainfall deficiencies

6-month rainfall deficiencies

The coverage of rainfall deficiencies for the 6-month and 12-month periods beginning in January 2005 and July 2004 respectively, are very similar with large areas affected from northwest WA to the east and south of the NT, as well as the far northwest of SA. Lowest on record totals are common. The heavy June rainfall removed or eased deficiencies in the far northeast of SA and the adjacent parts of western NSW, western Queensland and the southeast of the NT. Northern Tasmania is also affected over both time-spans, with an area to the east of Launceston having had its driest 12-month July to June period on record.
