Statement on Drought for the 7 and 10-month
periods ending 31st October 2004
Rainfall deficiencies removed along NSW coast & ranges
The Bureau of Meteorology announced today that heavy rain along parts of the NSW coast and adjacent ranges in October, removed rainfall deficiencies for the period since the start of April. This was particularly the case on the central and mid-north coasts where October totals were among the wettest 10% on record, and in some cases the highest on record going back to 1900. However, rainfall deficiencies persist between Grafton and Bowen, over Queensland’s Central Highlands and across some inland areas of southeastern Australia.
For the 7-month period from April to October, serious to severe rainfall deficiencies are evident along the east coast and Great Dividing Range from Bowen on Queensland’s central coast, to Grafton in northeast NSW. Deficiencies spread inland across the Central Highlands district in Queensland and into the Central West towards Longreach. Rainfall deficits also remain over and to the northeast of the ACT, and for the second successive month below average falls in southern WA caused a modest expansion of the areas affected by rainfall deficiencies since April.
For the 10-month period from January to October, serious to severe rainfall deficiencies affect the ACT and adjacent areas of southeast NSW, as well as parts of the Lower Western, and Riverina extending into northern Victoria. Serious deficiencies are analysed near and to the south of Mackay on Queensland’s central coast. Canberra’s year-to-date total of 278 mm is the driest for 10 years and the fifth lowest on record dating from 1939. The record low is 213 mm set in 1944.
Much of southern and eastern Australia continues to experience deficiencies for periods of two years and longer, and only a prolonged period of above average rainfall will remove them.
maps for standard periods (3, 6, 9, 12, 18, 24 and
36 months) are updated monthly on the Bureau's web site.
