Monstrous low pressure system to bring wild weather
A MONSTROUS low pressure system and strong cold front will hit eastern and southern parts of Australia this week.
Weather watch group Higgins Strom Chasing issued a warning late last night, saying forecasts and warnings needed to be taken "very seriously" and that potentially cyclonic weather could impact more than one quarter of Australia.
Higgins is warning that central pressure could drop down close to 970 hPa , with the brunt of the bad weather to be in South Australia and Victoria.
Meanwhile in Queensland, Bureau of Meteorology Forecaster Lauren Pattie said the combination of factors would bring widespread rain, showers and the chance of thunderstorms across most of the state.
"Currently we have a nice big high pressure system over us and this is leading to the sunny conditions we're expecting to see for the next couple of days, but we do have, over Western Queensland, an upper system and also a surface feature that is developing and is going to track from the west towards the east coast through Wednesday.
"Thursday is when it is expected to reach places around the Sunshine Coast.
"With that system we are expecting to see some patchy rain, tending towards showers after, and also the chance of some gusty thunderstorms, particularly in the afternoon and evening on Thursday."
The current forecast for Thursday is predicting a 70% chance of up to 8mm of rain.
Ms Pattie said coastal waters south of Fraser Island could expect strong winds on Thursday afternoon and evening.
Colder temperatures are expected to follow as the system tracks off shore on Thursday evening, with a maximum of 24C forecast for Friday.
Then it's "back to the sunny and warm conditions for the start of the weekend," Ms Pattie said.
