Deficiencies ease in Queensland, persist in W.A.

The Bureau of Meteorology announced today that above average November rains helped ease or eliminate rainfall deficiencies in southeast Queensland. However, there was generally little change to the pattern of deficiencies in Western Australia.

9-month rainfall deficiencies

The first map below shows the regions in southern and western W.A. with serious to severe deficiencies for the nine-month period from March to November. Above average falls eased the situation to the west of Kalgoorlie, but average to below average falls in other areas left deficiencies largely intact. Totals were the lowest on record for this particular period near the far southwest corner of the State, and to the east of Carnarvon. Most of western and southern W.A. also experienced rainfall deficiencies during the 2000 southern growing season.

12-month rainfall deficiencies

Rainfall in excess of 100 mm during November significantly eased or removed rainfall deficits in parts of southern and eastern Queensland, particularly in the area between Roma and Gladstone. For the twelve months from December 2000 to November, serious to severe rainfall deficiencies affect most coastal areas from St. Lawrence to Brisbane. Southeast Queensland also experienced well below average rainfall last year.
