Rainfall – Well above average rainfall

Monthly Rainfall Total: 263.7 mm (189.6 mm above average) and 479.1% of the long term average. This total is in decile 10/ 97th percentile which ranks as very high and 223.4 mm above the long term median (610.4 % of long term median). This is higher than the previous year which was 218.1 mm, the highest since 374 mm in 2010 and is the second highest on record.

 

All of the official sites in the Brisbane area measured above average rainfall with some sites close to average. Two sites ranked as average being Amberley at 119% of long term average with 87.2 mm which was the lowest total for the official sites and Cape Moreton Lighthouse with a total of 91 mm which was 115% of the long term average. The remaining sites measured between 118 and 239 % of the long term average of which many of these sites measured twice the October average rainfall. Many of these ranked as high ranging of between 118% (Point Lookout with a total of 114 mm) and 239% of the long term average (Logan City Treatment Plant with a total of 162.6 mm). Two sites measured rainfall that ranked as very high at 227% of the long term average for both sites being 179.2 mm at Brisbane and 205.4 mm at Beerburrum (the highest total of the official sites).

 

The above average rainfall was a result of numerous showers and thunderstorms in the Brisbane area. Mt Tamborine recorded it highest October rainfall total in 46 years with a total of 373.9 mm, while Corbould Pk Racecourse recorded a new record high for October total rainfall exceeding the old record of 327 mm in 2017 and recording 413 mm for the month.

 

Number of Rain Days: 20 days, 8 higher than this month last year and 12.4 days above average. This is the second highest on record whilst the record high is 22 days in 2017.

 

Highest Daily Total: 56.5 mm on 6 October 2018. This is the highest since 61.8 mm on the 12 October 2010 and the fourth highest October daily rainfall on record. The wettest location in the Brisbane area of all official sites was 90 mm at Mt Tamborine Fern St on the 16 October 2018.

 

Monthly Rainfall Total – (automatic gauge) 24 hours to 9am: 247.1 mm (16.6 mm less than official standard gauge and within 6.2%). Highest daily total (automatic gauge, 24 hours to 9am): 59 mm on the 6 October 2018, (24 hours from midnight): 40.6 mm on 6 October 2018.

 

Note: This automatic gauge is developing rust on its magnet which is possibly affecting its accuracy. Based on the performance of a similar gauge with a failed switch it is expected the accuracy of this gauge will be affected and become erratic as this fault develops further and was decommissioned from use from 5 October and replaced with new equipment. For the month of October, the combined rainfall total meet the expected accuracy (of +/- 10% of the standard gauge) of -6.2%.

Weather influences

• A high pressure system shifted east over the Tasman Sea extending a ridge and onshore winds on the 1st and the ridge was maintained on the 2nd
• The ridge and onshore winds started to weaken on the 3rd and further on the 4th as the high pressure system shifts further east
• A surface trough shifted eastwards over the interior on the 4th extending a warm air mass, along with a upper trough
• The surface trough and upper trough shifted further east on the 5th with showers and thunderstorms as a result
• The trough system moved over the region on the 6th with further instability and cleared late in the day
• Light onshore flow on the 7th in the wake of the trough moving further north, which brought some showers and storms
• A weak ridge remained in place on the 8th with a slow moving surface trough and upper trough over the interior maintained unstable conditions
• On the 9th unstable conditions remained with a upper trough over central and eastern parts of the state
• A surface trough shifted east over the interior and combined with the upper trough to continue to bring showers and thunderstorms on the 10th. A coastal trough shifted north along the coast in the evening
• On the 11th an upper trough moved east and off the coast with another shifting eastwards. This and a surface trough continued to bring showers and thunderstorms. A coastal trough shifted further northwards allowing a ridge and onshore winds to extend northwards
• The ridge and onshore winds remained in place on the 12th as a high pressure system shifted eastwards. A surface trough and upper trough to the west maintained showers and storms
• On the 13th an eastward moving coastal trough deepened off the coast, with a circulation developing on this trough. This combined with the persisting ridge brought further rainfall
• On the 14th rainfall continued with an upper trough shifting across the region. A coastal trough lied off the coast with a low pressure centre south of Fraser Island and another further south on this trough
• On the 15th an upper trough moved east over the region and out to sea later in the day. A coastal trough remained off the coast and extended north to Fraser Island with several lows on the trough with the main centre to the southeast of Fraser Island, and enhanced the rainfall
• Showers persisted on the 16th with the coastal trough and low near Fraser Island weakening and shifting offshore. The onshore winds and ridge remained in place
• The 17th saw the ridge and onshore winds combining with a few weak troughs in the Coral Sea to maintain some shower activity
• The ridge started to ease on the 18th and maintain shower activity
• On the 19th and 20th the ridge extended some onshore winds before decaying on the 21st
• A surface trough remained slow moving through the interior of the southeast and along with an upper trough extended a moist and unstable air mass eastwards
• The surface trough cleared offshore on the 22nd, though the moist air mass with a surface trough over the interior
• With a trough inland on the 23rd supressed upper level conditions brought stable conditions
• A trough remained inland on the 24th and extended a warm, moist and unstable air mass. A coastal trough shifted northwards along the coast later the day aiding the instability.
• A persistent high pressure system in the Tasman Sea extended a weak ridge on the 25th, while an inland trough maintained unstable conditions
• The surface trough remained in place on the 26th and extended dry, hot and stable air, before a coastal trough shifted northwards late in the day with a cool and moist south-easterly wind change
• A weak ridge developed on the 27th with light winds
• On the 28th an upper trough shifted eastwards and along with an inland surface trough that shifted north-eastwards brought unstable conditions. A coastal trough also shifted northwards followed by a south-easterly wind change
• On the 29th, in the wake of the coastal trough a ridge and onshore flow extended northwards. The surface trough inland and a upper trough brought some instability
• The 30th and 31st saw the ridge decay as the high pressure system shift northwards
