Get the um­brel­las ready, there’s rain on the way

The Queensland Times - - NEWS -

THE good news is it’s go­ing to rain - you can just about bet your house on it.

The bad news is it prob­a­bly won’t be un­til next week and no-one can guar­an­tee how much we’ll get.

As the pro­longed spell of dry weather con­tin­ued and the coun­cil made emer­gency sup­plies avail­able for peo­ple liv­ing on tank water, Weather­zone me­te­o­rol­o­gist Graeme Brit­tain had some good news.

“There’s a pretty good chance of rain in south-east Queens­land at last,” he said.

“It looks like you’ll get rain later in the week, maybe Wed­nes­day, Thurs­day and Fri­day.”

A low pres­sure trough is fi­nally due to move into the re­gion and have an im­pact on the high pres­sure sys­tem which has kept the rain away for so many weeks.

That will mean an ex­cel­lent chance of show­ers, thun­der­storms and a fresh set of leaves for the city’s jacaranda trees, which drop their bounty at the end of the dry sea­son, then leaf up again when the rain comes.

The big ques­tion is “how much rain?”. That de­pends on how things change.

“I can say that it is more likely than not that you will get rain but if it’s pass­ing show­ers, you might only get 5-10mm,” Graeme said.

“If it’s some de­cent storms, any­thing is pos­si­ble. It could be 10-20mm in lo­calised falls.”

Weather­zone’s web­site has a 40% chance of rain in the area on Wed­nes­day, 30% on Thurs­day and 50% Fri­day.

It will make a welcome change af­ter a month which has seen just 1.6mm of rain fall in 16 days - all of it on Septem­ber 5.

The long-term av­er­age for Septem­ber is 63.5mm, with the heav­i­est falls of 249.8mm recorded in 2007.

The dri­est Septem­ber on record was in 2000 when just 0.8mm was recorded.

Graeme said the longer-term out­look was more promis­ing, with a good chance of “closer to av­er­age” falls for the re­gion in Oc­to­ber and Novem­ber.

■ The Bureau has fore­cast pos­si­ble show­ers for Ip­swich on Fri­day with 100mm ex­pected be­fore Novem­ber.
