QLD rain, some record October falls

October 16, 2017

The most outstanding weather event of the last few days has been the widespread rain in Central and Eastern districts of Queensland. Some places along the coast between Mackay and Brisbane have had record rainfalls for October.

Sandy Cape has received a total of 288 mms up to 15th October. It is already the wettest October there in 146 years of records. Bundaberg has received a total of 272 mms up to Sunday 15th October and is just short of the record wet October of 1953.

St. George received a further 47 mms last Thursday 12th October taking this month's total to 98 mms the highest to mid October since 1949. After one of the driest June to September periods on record at St. George with only 19.4 mms rainfall, this is an amazing turnaround.

The only other time this happened in 137 years of records was in 2000. There was flooding rains late October and in November in 2000 at many places in our region.

Other very wet Octobers at St. George were in 1886, 1892, then a break of 42 years to October 1934, Five very wet Octobers between 1946 and 1955, October 1969 and October 2000. Spring and Summer following these past wet Octobers at St.George were indeed wet, humid with high frequency of thunderstorms at most places in our regions.

The widespread rain in QLD is due to an extensive low pressure trough over northern areas. Together with a high pressure system over Tasmania this constitutes a blocking pattern, allowing more rain in QLD in the next two days.

The approaching low pressure trough over WA will bring warm to hot days this coming week to our regions followed by rain and thunderstorms during the weekend of 21st-22nd October.
