Ex-Tropical Cyclone Oswald has delivered close to 600mm of rain in just 24 hours to parts of Queensland's central coast, while damaging winds and high seas pounded the region. Very heavy rainfall and gale force winds will develop in Brisbane tonight and will intensify further during Saturday. Widespread rainfall totals of 100 to 200mm soaked areas between Proserpine and Bundaberg in the 24 hours to 9am this morning. The largest totals fell around Rockhampton, where some areas recorded daily totals of close to 600mm. Rockhampton itself recorded 349mm in the 24 hours to 9am this morning, which was its heaviest daily total in 70 years of records. Ex-Tropical Cyclone Oswald is responsible for this deluge that affected the Queensland tropics before pushing south through the state's central interior. As the system continues to move in a south to southeasterly direction the heavy rainfall and strong winds will ease from Rockhampton this evening, while the severe conditions spread towards the state's southeast tonight. A severe weather warning remains in place for the Capricornia, Central Highlands and Coalfields, Wide Bay and Burnett, Southeast Coast and Darling Downs and Granite Belt for the threat of damaging winds and heavy rainfall that may lead to flash flooding. The warning also includes the risk of abnormally high tides and dangerous surf for the central and southeast coasts, which could lead to beach erosion and flooding of some low-lying areas close to the shoreline. For the remainder of today, the heaviest rainfall will affect areas between Rockhampton and the Sunshine Coast, before spreading into Brisbane tonight. The heavy rainfall and strong winds will then spread to the New South Wales border during Saturday. Brisbane is likely to see rainfall totals in excess of 200mm during this weekend, which could lead to flash flooding and significant stream rises. The city could also see damaging winds gusts reaching 90km/h during Saturday and into Sunday, with coastal areas at the highest risk. Winds of this strength combined with very heavy rainfall could bring down trees and power lines. The heavy rainfall is expected to continue into Monday morning across southeast Queensland, before easing to scattered showers. By Tuesday skies are expected to clear as temperatures warm with humid conditions. For the latest warnings and forecasts check weatherzone.com.au.
