Queensland in December 2010: 

The wettest December on record

*Updated information*  Special Climate Statement 24 was first issued on the 7th Jan 2011 with updated details on the widespread flooding across eastern Australia in Dec 2010.

Queensland experienced yet another month of widespread rainfall under the influence of a strong La Nia and followed the wettest spring on record. Flooding continued across many southern and central Queensland river systems. Many significant weather systems affected the state bringing torrential rainfall at times and severe thunderstorms battered the southeast coast between the 15th and 18th. A weak category one tropical cyclone Tasha crossed the coast south of Cairns early on Christmas morning and continuing active monsoonal activity led to a wet Christmas period that culminated in one of the most widespread and significant floods in Queensland's history.

  • The wettest December on record
  • One of the most significant floods in Queensland's history
  • Record flooding across southern and central catchments
  • Queensland's first cyclone of the season, Tasha, crossed the coast south of Cairns on Christmas morning
  • Severe thunderstorms with large hail in the southeast
  • There were 26 high daily rainfall and 107 high December total rainfall records
  • There were 16 low daily and low mean maximum temperature records
  • There were 7 high daily and mean minimum temperature records 

Weather Summary

At the beginning of December a slow moving high-pressure system over the Tasman Sea extended a ridge along the east Queensland coast, a surface trough lay through the western interior and an upper trough was approaching the state from the west. Moisture laden northeasterly winds extended to the inland trough and combined with the unstable upper atmosphere, showers, thunderstorms and rain areas developed across most of the state. Widespread rain areas with some heavy falls persisted for the next two weeks as a series of upper troughs moved through the state and enhanced existing or triggered new flooding in many river systems. The development of several near coastal surface troughs also enhanced the rainfall and moderated local winds. Fine conditions returned to western Queensland and gradually spread east as the final upper trough cleared the coast, though shower activity persisted along parts of the east coast and shower and storms over the northern tropics. Two of the heaviest daily falls during this period were at Escott Station in the southern Gulf of Carpentaria where 266 mm was recorded on the 11th from a line slow moving storms and at Mount Charlton with 228 mm on the 3rd. 

On the 15th the upper trough was offshore but upper temperatures remained cool and surface moisture remained high in the east, making conditions  unstable. A surface trough entered the the far south west and moved slowly east and scattered showers and thunderstorms developed to the east of the trough in the south over the next few days. Severe storms produced large hail, damaging wind and torrential rain in the southeast during the 15th and 18th. During the 17th a surface trough moved east into south-east Queensland and the following day a coastal trough moved north along the southern Queensland and combined with mid-level instability triggered showers and thunderstorms from north-west Queensland to the southeast.

During this time most of northern Australia, including all Queensland, was covered  by cloud  that developed near a deep low of the Western Australian coast and in a developing monsoon flow across northern Australia and was further developed and advected east by mid and upper- level troughs. Thundery rain developed across southern and central interior districts and the south-east with moderate to heavy falls and showers and thunderstorms  continued in the tropical north.

During the 20th upper trough activity was weakening and the surface trough pushed northward followed by a much cooler, drier air  and clear skies spread across southern Queensland and contracted the heavy rain to the north of the state. 

Following the extended period of wet weather over the previous weeks the following flood warnings were current for the 20th: Barcoo, Bulloo, Don, Condamine, Balonne, Moonie, Paroo, Warrego, the Fitzroy River basin, Brisbane River above Wivenhoe Dam, the Burnett Catchment, Mary River and Cooper Creek, Laidley and Warril Creeks and the Bremer River. 

A low pressure system deepened in the Coral Sea and formed into tropical cyclone Tasha  early on Christmas morning and crossed the coast about 5:30 am south of Cairns between the townships of Gordonvale and Babinda.  It was a weak category one system but brought significant rain to a broad area of northern Queensland. The active monsoonal conditions continue and further widespread and heavy rainfall affected northern, central and eastern Queensland during the Christmas period Christmas period leading to one of the most significant flooding events in Queensland's history. Theodore and Condamine were fully evacuated and 22 towns and over 200,000 people were affected. 41 local government areas were disaster declared with significant disruption to mining and agricultural and other industries expected to cost many hundreds of millions of dollars.

Tropical cyclone Tasha

Queensland's first cyclone of the 2010/11season, Tasha, formed early on Christmas morning near Agincourt Reef to the east of Cairns and crossed the coast about 5:30 am south of Cairns between the townships of Gordonvale and Babinda. It was a weak category one system but brought significant rain to a broad area of northern Queensland.

Very extensive flooding

Following very extensive and heavy rainfall periods during the past few months, river catchments were overwhelmed by further rainfall in December that culminated in one of the most widespread and significant floods in Queensland's history. Theodore and Condamine were fully evacuated and 22 towns and over 200,000 people were affected. 41 local government areas were disaster declared with significant disruption to mining and agricultural and other industries expected to cost many hundreds of millions of dollars. 

Abnormally high tides

Some parts of southeast Queensland had had tides 20-30cm above the normal expected tide before Christmas, easing off further north. This extra height pushed the tides above the high water mark on the highest tide of the day.The majority of this anomaly is thought to be related to La Nia when stronger than normal trade winds act to pile up water on the western side of the Pacific. These high tides were not King tides.

Rainfall

Area averaged across the state rainfall was the highest on record this December with 209.45 mm based the on the dataset beginning in 1900 and more than double the long term 1961 to 1990 baseline mean of 82.48 mm. The previous highest December record was 200.1 mm in 1975. Average or greater rainfall was recorded throughout the state, with all eastern and central districts receiving very much above average and large areas the highest on record. The continuing rainfall and further heavy falls after the wettest spring on record culminated in one of the biggest flood events to affect the state during the Christmas period. For many towns this would have been one of the biggest weather events in living  memory.

Rainfall anomalies of 200 mm or greater than average cover most of the Central Coast & Highlands, Port Curtis, Moreton and parts of the southern interior and Carpentaria with some parts more than 500 mm. Some of these areas had received more than twice the December average rainfall. All the near average rainfall was recorded in western far southern interior areas.The northern wet season which runs from October to April has already seen amongst the highest 10% of rainfall on record over almost all the state  and large areas have already exceeded the highest on record.

The wettest overall for December was Bellenden Ker Top Station with 1221.2 mm, followed by Mount Charlton with 1173.1 mm and  Mt Jukes with 1007.4 mm.

The driest overall was the southwest corner and Birdsville Airport recorded 2.0 mm.

Some sites had their highest total December rainfall on record. Some sites had their highest total December rainfall for at least 20 years. Some sites had their lowest total December rainfall on record.

The wettest single day was at Babinda Post Office with 294.0 mm on the 25th.

Some sites had their highest December daily rainfall on record. See a map of total rainfall. See a map of rainfall deciles.

Temperature

The coolest on average was Applethorpe with 18.5 C, followed by Stanthorpe Leslie Parade with 19.2 C and Toowoomba Airport with 20.1 C.

Maximum temperature

The widespread and frequent rain bearing weather systems kept daily maximum temperatures well below average on many days in December. The mean maximum was within a degree of average over much of the northeast tropics and coastal fringe between Agnes Waters and the northern Sunshine Coast. For the remainder, mean maximum temperature anomalies were well below average and especially through the central and southern interior with a large part more than 4 C cooler. The December  maximum temperature decile map depicts  lowest on record areas in the Central Highlands and southeast interior districts. This anomaly pattern is similar for the three-month period October to December 2010 and is a welcome relief from the normally hot periods experienced at this time of year.

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Queensland using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

This statement has been prepared based on information available at 9 am on Tuesday 4 January 2011. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

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 9 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (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.
