MEDIA RELEASE - ISSUED 6th OCTOBER 2000

Statement on Drought for the 6, 8, & 48-month periods ending 30th September 2000

Rainfall deficits intensify in W.A.

The Bureau of Meteorology announced today that during the past six months large areas of southwest Western Australia have experienced severe rainfall deficiencies. Parts of southeast Queensland and northeast New South Wales are similarly affected. Despite above average falls in September over much of southeastern Australia, parts of Victoria, Tasmania and South Australia are still experiencing longer-term deficiencies.

Relatively dry weather in September exacerbated rainfall deficiencies in Western Australia, southeast Queensland and New South Wales. For the six months from April to September 2000 a large region in the west of W.A. is experiencing severe deficits (see first map below). Rainfall deficiencies for this period are also evident on the central NSW coast and the border region of northeast NSW - southeast Queensland.

The eight months from February to September 2000 were also deficient in rainfall over southeast Queensland and northeast NSW, but in comparison to the 6 months the affected region spreads further north and east to the coast. (see second map below)

The rainfall for the past 48 months has been markedly below average over southern Victoria, the southeast of S.A., together with the north and east of Tasmania. Above average September rainfall barely changed this pattern. (see third map below)


Rainfall deficiency maps for standard periods (3, 6, 9, 12, 18, 24 and 36 months) are updated monthly on the Bureau's web site, at http://www.bom.gov.au/cgi-bin/silo/rain_maps.cgi .
