Another rainy week ahead in Brisbane March 10, 2013 - 6:00PM Weatherzone: Brisbane storm tracker It has rained 22 out of the past 24 days in Brisbane and a reprieve is not certain by the end of the week. The rain continues to pour as a second cyclone forms in the Gulf of Carpentaria and Cyclone Sandy officially moves out of Australian waters. Weatherzone forecaster Drew Casper-Richardson said 10 days into March, 140 millimetres had already fallen on Brisbane, higher than the average for the entire month of 97 millimetres. "The rain is due to a really, really slow - almost stationary low - pressure system," he said. It's driving all the moist easterlys which is making it really humid as well as driving showers. I'm sorry to say it's going to be much the same until Thursday or Friday. Mr Casper-Richardson said there were no certainties skies would clear by next weekend. Meanwhile, Cyclone Sandy morphed into a Category 3 cyclone but has officially drifted out of Australian waters. It is now being monitored by Fijian authorities instead of Australian ones though nervous eyes are cast back to the Gulf of Carpentaria where a low system is forming, which could potentially turn into a cyclone. The cyclone is supposed to form by Wednesday. If it does it will be named Cyclone Tim. "It doesn't actually exist yet," Mr Casper-Richardson said. There is still some modelling being done about what direction it could head in too. The Bureau of Meteorology says Cyclone Sandy is likely to reach a category four early on Monday morning but would be downgraded as it heads towards New Caledonia on Monday and Tuesday. It should not do too much damage to the islands in the area, with gale force winds and rain predicted on land but the worst of it staying out to sea.
