Tuesday, 1 March 2011 - Monthly Climate Summary for Queensland - Product code IDCKGC14R0
The current La Niña event has shown signs of weakening during February. Two February daily rainfall records and one monthly rainfall record occurred over the tropical areas close to the location of the monsoon trough early in the month. One of the daily records happened over the Central Highlands area and this was related to a cut off low near the Central Coast during the 8th and 9th. The state-averaged rainfall total for February was 132.87 mm, slightly above the long-term average of 115.61 mm.
Queensland state-averaged mean temperature for February was 0.02 oC above the long-term (1961-1990) average of 28.19 oC. The state-averaged maximum temperature was 0.14 oC below the long-term mean of 33.99 oC, while the state-averaged minimum temperature was 0.18 oC above the long-term mean of 22.39 oC.
Tropical Cyclone Yasi formed in the Fijian area of responsibility near the end of January and quickly intensified to from a Category 3 to a Category 4 on the 1st of February then accelerated its movement towards the tropical Queensland coast. Tropical Cyclone Yasi upgraded to a marginal Category 5 system during the morning of the 2nd of February and made landfall on the southern tropical coast near Mission Beach between midnight to 1 am early on the 3rd. Severe Tropical Cyclone Yasi maintained a strong core with damaging winds and heavy rain, tracking westwards across the northern parts of the state and finally weakened to a tropical low near Mount Isa around 10pm on the 3rd. A barograph at the Tully Sugar Mill recorded a minimum pressure of 929 hPa as the cyclone eye passed over the suggesting wind gusts of about 285 km/h were possible. Significant wind damage was reported between Innisfail and Townsville. A 5 metre tidal surge was observed at the DERM storm tide gauge at Cardwell. Widespread rain areas with moderate to heavy rainfalls had remained over the northern parts of the state during the 4th and 5th as the Ex-Tropical Cyclone Yasi moved into the NT as a low pressure system.
On the 5th and 6th, a middle to upper level trough over the western Coral Sea moved into eastern Queensland, leading to an enhanced area of rain showers and thunderstorms over the central districts and into the Wide Bay and Burnett district. Showers then eased over the shoutheast of the state.
A surface trough over the southern interior on the 7th shifted towards the northeast and merged with a cut off low near the central coast. As a result, scattered showers and thunderstorms over the southern interior parts of the state on the 7th were pushed over the southeast o the state, the Capricorn Coast and the Wide Bay areas , with some moderate to heavy falls during the 8th and 9th.
On the 10th, a high over the Tasman Sea had extended a ridge across the southeast of the state. Fine weather conditions were dominated the southeastern parts of the state over the following days while some isolated showers persisted along the southeast coast.
A deep and slow moving trough remained over the southwestern border area during the 13th to 18th and produced scattered showers and thunderstorms with some moderate to heavy falls over the southwestern and western regions.
From the 13th to 16th, an upper low over the Queensland central coast maintained unstable conditions along the coast and adjacent inland parts with some showers and thunderstorms over the area.
A deep surface trough entered into the southwestern districts on the 19th and triggered scattered showers and thunderstorms over the southern and southwestern districts on the 21st. This trough pushed the scattered showers and thunderstorms over the southeast quadrant and into most central and northwestern parts of the state on the 22nd.
Rain areas and storm activity persisted over the northern parts of the state, particularly over the Cape York Peninsula, for the rest of the month due to the monsoon trough over the northern tropics. Fine weather conditions dominated the southern and most of the central parts of the state during this period, apart from some very isolated showers over the southeast.
Tropical Cyclone Yasi formed in the Fijian area of responsibility near the end of January and quickly intensified to from a Category 3 to a Category 4 on the 1st of February before accelerating towards the tropical Queensland coast. Yasi upgraded to a marginal Category 5 system in the morning of the 2nd of February and made landfall on the southern tropical coast near Mission Beach between midnight to 1 am early on the 3rd of February. Severe Tropical Cyclone Yasi maintained a strong core with damaging winds and heavy rain, tracking westwards across the northern parts of the state and finally weakened to a tropical low near Mount Isa around 10pm on the 3rd of February.
Yasi was one of the most powerful cyclones to have affected Queensland since records commenced. Previous cyclones of a comparable measured intensity include the 1899 cyclone Mahina in Princess Charlotte Bay, and two cyclones of 1918 at Mackay (January) and Innisfail (March). More details please refer to the Report of Severe Tropical Cyclone Yasi.
During the February, rainfall totals were below the long-term averages over most parts of the southeastern parts of the state, the central interior and the western half of the Cape York Peninsula. Areas with total rainfalls very much below the average (decile 10) were over parts of the eastern Darling Downs, the Central Coalfields and the southwestern parts of Cape York Peninsula.

The February mean maximum temperatures were 1 to 2 oC below their long-term averages over the southern districts, most of the central coast, the western parts of the central interior, and the western half of the Cape York Peninsula. For the eastern parts of the central interior and most of the central coast, their maxima were 1 to 2 oC below the long-term means and 2 to 4 oC below average over the northwestern districts.
The February mean minimum temperatures were near or 1 oC above the long-term means over the southern districts, along the central coast as well as the southwestern parts of the Cape York Peninsula. Particularly, about 1 to 3 oC above the means near the southern border areas. For most northern and central interior parts, the monthly mean minimum temperatures were near or 1 oC below the long-term means.

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 10 am on Tuesday 1 March 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
(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.
