Friday, 1 May 2009 - Monthly Climate Summary for Queensland - Product code IDCKGC24R0
At the beginning of the month, a surface trough was located off the southern coast of Queensland, with a low embedded in this trough. Aided by an upper level low pressure system the combination produced areas of moderate to heavy falls over the southeast coast. After midday on the 2nd, flood warnings were issued for the Sunshine Coast streams as very intense rainfall of 150 to 300 mm was recorded over the previous 3 hours in the northern areas of the Sunshine Coast (including the catchments of the Noosa and Maroochy Rivers, and Six Mile Creek). Flood warnings were also issued for the Mary River and tributaries as similar falls of 150 to 300 mm were recorded in the same time period in the Cooroy and Pomona area to the west of Noosa. Between 9am and 3pm on the 2nd, 413 mm fell inland of Noosa, while places around the Sunshine Coast recorded 130 mm. Black Pinch Road Alert recorded 464 mm to 9am on the 3rd.By the 3rd, the trough lay off the Wide Bay coast and was moving north, and weakening. Rainfall continued around the Sunshine coast hinterland, the Gold Coast hinterland, eastern Darling Downs, Capricornia and Wide Bay districts. The southern quarter of the state recorded the heaviest rainfall in the first week of the month.
On the 13th, a surface trough was lying near the Capricornia and southeast Queensland coast with an upper level trough located over the southern interior.

This statement has been prepared based on information available at 10 am on Friday 1 May 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
Please note that the rainfall data from Bureau of Meteorology telemetry gauges (those with ALERT, AL or TM in their names) includes real-time operational data from automated systems and has not been checked.
Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably. *In this case, averages from a nearby suitable site have been used instead (these are marked with an *).
The temperature anomaly maps are calculated with respect to the reference period 1961−1990. The rainfall decile maps are based on a reference period comprising all gridded analyses from 1900 to the present available at the time the deciles are calculated
The Rank indicates how rainfall this time compares with the climate record for the site,
based on the
(very low rainfall is in decile 1, low in decile 2 or 3,
average in decile 4 to 7, high in decile 8 or 9
and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
