Queensland in January 2011: Widespread flooding continuedSpecial Climate Statement 24 (SCS 24) titled 'Frequent heavy rain events in late 2010/early 2011 lead to widespread flooding across eastern Australia' was first issued on 7th Jan 2011 and updated on 25th Jan 2011.
- High rainfall totals in the southeast and parts of the far west, Cape York Peninsula and the Upper Carpentaria
- Widespread flooding continued
- There was a major rain event from the 10th to the 12th of January in southeast Queensland
- TC Anthony crossed the coast near Bowen on the 30th of January
- The Brisbane Tropical Cyclone Warning Centre (TCWC) took over responsibility for TC Yasi on the 31st of January
- There were 12 high daily rainfall and 13 high January total rainfall records
- Queensland's area-averaged mean maximum temperature for January was 0.34 oC lower than average
SummaryJanuary total rainfall was very much above average (decile 10) over parts of the Far Southwest district, the far west, Cape York Peninsula, the Upper Carpentaria, the Darling Downs and most of the Moreton South Coast district, with some places receiving their highest rainfall on record.
The current La Niña event, which is one of the strongest on record (see SCS 24, page 3), has contributed to the extremely wet period experienced in Queensland from late November 2010 to mid January 2011 (see SCS 24, page 6 and Fig. 2). La Niña events are normally associated with higher than average winter, spring and early summer rainfall over much of Australia. Indeed, Queensland had its wettest spring on record in 2010 (see the summary at: http://www.bom.gov.au/climate/current/season/qld/archive/201011.summary.shtml) and its wettest December on record (see the December Monthly Weather Review at: http://www.bom.gov.au/climate/mwr/qld/mwr-qld-201012.pdf.)
This extremely wet period from late November 2010 to mid January 2011 contributed to widespread flooding of many Queensland rivers. During the second week of January severe flooding (including river and flash flooding) occurred in Brisbane and nearby areas of southeast Queensland. For more information see SCS 24, pages 7, 8 and 9.
Eleven January daily rainfall records occurred in the Moreton South Coast district between the 10th and 12th of January (at stations with more than twenty years of data), four of which were also all-time daily rainfall records, and one January daily rainfall record occurred at Cooby Creek Dam in the East Darling Downs district on the 11th.
Queensland's area-averaged mean maximum temperature for January was 0.34 oC lower than average (based on data since 1950). During La Niña events, summer daytime temperatures are often below average, particularly in areas experiencing excess rainfall.
Main Weather SystemsAt the beginning of the month a high pressure system in the Tasman Sea extended a ridge along the east Queensland coast. Showers occurred along the east coast, becoming scattered about the Northern Tropical Coast. The monsoon trough through Torres Strait strengthened a little and showers and thunderstorms occurred over much of the tropics. The ridge along the east coast weakened on the 2nd, allowing the monsoon trough to slip southwards onto Cape York Peninsula. On the 2nd and 3rd, showers and thunderstorms occurred about eastern and northern districts and to the east of a trough over the far southwest of the state. On the 3rd, a deep mid-level depression and surface circulation off the southeast Queensland coast drifted south-southeasterly with freshening southeasterly winds about the southeast coast. Showers and thunderstorms occurred across much of the state on the 4th.
Conditions cleared in the southwest on the 5th, while showers and isolated thunderstorms occurred in the high levels of instability ahead of the surface trough. The trough intensified as it moved slowly east and thundery rain areas with some heavy falls developed in the afternoon. An approaching upper level trough increased instability over the southern Queensland interior and occasional thunderstorms developing through the central and southern interior in the afternoon. Thunderstorm cells merged into thundery rain areas with moderate to heavy falls by evening as far north as the southern Central Highlands and Coalfields, spreading east during the evening and overnight.
On the 6th, an upper level low developed over the southeastern interior of Queensland. Scattered showers and thunderstorms occurred to the east of a slow moving surface trough that extended from northwestern Queensland into the Darling Downs. Rain areas and thunderstorms increased through the Southeast Coast District and eastern parts of the Wide Bay and Burnett District during the afternoon, with some heavy falls.
The position of the upper level low close to Rockhampton and a low level trough near Bundaberg on the 7th resulted in a focus of heavy rainfall over the Wide Bay with thunderstorms. The highest daily rainfall total recorded in Queensland during January by the Bureau's regular network was 304.0 mm over the Mary River catchment at Miva in the 24 hours to 9am on the 8th. Thunderstorms also developed in the Capricornia and eastern parts of the Central Highlands. There were some moderate falls during the morning in the southeast as a band of rain and thunderstorms crossed. Wind speeds increased on the southern side of the low over southeast waters.
Heavy rain overnight weakened to showers and isolated thunderstorms before rain areas returned to the Southeast Coast and Wide Bay and Burnett districts from the afternoon of the 8th and increased to moderate to heavy falls at times overnight.
On the 9th, the upper level and surface troughs moved towards the west. Heavy rain areas and thunderstorms occurred about northern and central parts of the Southeast Coast District, southern parts of the Wide Bay and Burnett District, and northeastern parts of the Darling Downs and Granite Belt district. In the 24 hours to 9am on the 10th, Peachester recorded 298.0 mm and Maleny Tamarind St recorded 282.6 mm.
Please see SCS 24 (page 4 and a comparison with previous events on page 7) for further information about the major rain event that brought very heavy rain to southeast Queensland between the 10th and the 12th of January.
TC Vania formed in the Fijian area of responsibility and was named on the 12th of January (see below).
On the 13th, a sharp surface trough was located over the west of the state and a deep northerly flow brought showers, thunderstorms and rain areas to the west and north of the state with some moderate to heavy falls. On the 14th, this trough moved a little further east with a band of very active showers and thunderstorms through western districts and the southern tropics. TC Zelia formed in the northern Coral Sea and was named on the 14th (see below).
Showers and thunderstorms continued near and to the east of the surface trough located over western Queensland on the 15th, while ridging over southeastern and central parts of the state resulted in mostly fine conditions with only isolated showers near the coast and adjacent inland. The monsoon trough over Cape York Peninsula began creeping south on the 16th, with rain areas and thunderstorms occurring over the tropics. Isolated showers occurred along the east coast. Instability increased further west towards a weak surface trough and isolated afternoon showers and thunderstorms developed east of the trough on the 16th and 17th. Locally heavy activity occurred in the northwest of the state in a convergence zone.
By the 18th the monsoon trough was located at the northern end of the central coast with showers and thunderstorms to its north and some locally heavy falls. The surface trough extended from northwest Queensland to the southeast interior, with scattered showers and thunderstorms occurring to its east. Fine conditions occurred over most of the Channel Country and southwestern Maranoa and Warrego districts in the drier southerly flow. The monsoon trough began to move north on the 21st, contracting activity, and only isolated showers and thunderstorms occurred over the interior of the rest of the state as the surface trough moved west and weakened.
From the 22nd, a middle level ridge over western Queensland resulted in fine conditions over most of the state. The heavy rain and thunderstorms about the monsoon trough and over the northern tropics contracted to over Cape York Peninsula by the 23rd. TC Anthony was named on the 23rd (see below). Daily maximum temperatures increased to up to 6 oC above average in the far southwest of the state in the northwesterly flow ahead of a very slow moving trough over South Australia on the 23rd and the hot conditions continued to spread northeast over the following days (see the maximum temperature section below for more details).
On the 27th isolated showers and thunderstorms developed near the surface trough over the west of the state. The trough weakened by the 30th and maximum temperatures were closer to average, within 2 oC of average over most of the southwest.
TC Anthony crossed the coast near Bowen on the 30th (see below).
At the end of the month, major flooding extended along the Condamine-Balonne Rivers from Warkon to the NSW Border and minor to major flooding was occurring along the Weir River between Surrey and Jericho.
The Brisbane TCWC took over responsibility for TC Yasi at about midnight on the 31st of January (see below).
TC VaniaTC Vania formed in the Fijian area of responsibility and was named on Wednesday the 12th of January. It remained outside the Australian area of responsibility but caused swells to increase about the southeast Queensland coast between the 15th and 17th.
TC ZeliaTC Zelia formed in the northern Coral Sea and was named on Friday the 14th of January. It moved away from the Queensland coast in a generally southeasterly direction. Responsibility for Severe Tropical Cyclone Zelia was transferred to RSMC Nadi on Sunday the 16th of January as it moved into the Fijian area of responsibility.
TC Anthony formed in the western Coral Sea and was named on Sunday the 23rd of January. It initially moved away from the Queensland coast and weakened below tropical cyclone strength during the afternoon of the 25th of January, then began to move in a generally northwesterly direction. At 12pm on the 28th of January Ex-TC Anthony was renamed. It began to move west/southwest on the 29th and crossed the coast near Bowen just before 10pm on the 30th as a category 2 cyclone. A wind gust of 128 km/hr was recorded at Hamilton Island Airport at 8:11 pm on the 30th. Bands of heavy rain affected the Central Coast and northern Coalfields. The heaviest rainfalls occurred about the Pioneer River catchment. Minor flooding occurred on the Don River and minor to moderate flooding on the Pioneer River.
TC YasiTC Yasi formed in the Fijian area of responsibility near the end of January and moved west with the Brisbane TCWC taking over responsibility for it at about midnight on the 31st of January.

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 11 am on Tuesday 1 February 2011. Some checks have been made on the data, but it is possible that results will change as new information becomes available.* These sites are compared to other long-term sites in the area using the 1961 to 1990 period where available for Brisbane temperature, the 1981 to 2004 for Redcliffe temperature and all years of record for rainfall.
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.
