A low pressure system forming over the Coral Sea is likely to bring flooding rain, blustery winds and dangerous surf to QLD's central and southeast coasts. A low developing just off the QLD coast will deepen and move south, causing wind and rain to increase from about Rockhampton to the NSW border. This system has already brought heavy falls, with 109mm recorded in Hamilton Island and 79mm at Mackay in the 24 hour period to 9am this morning. St Lawrence had their heaviest rain this month with 48mm to 9am, while Samuel Hill Airport recorded 82mm, their biggest February rain for three years. Elsewhere, Nambour on the Sunshine Coast had 56mm, with 69mm at Hervey Bay and 56mm at Redlands, east of Brisbane. As the low intensifies so will the rain, with falls of 100-200mm likely for many places from the central to the southeast coast. The Wide Bay and Burnett and Sunshine Coast look likely to see the most rain, where falls of more than 200mm are possible. Along with the rain, flooding, blustery winds and dangerous surf leading to coastal erosion are likely for some areas. A flood warning has been issued for coastal rivers and adjacent inland catchments from St Lawrence to the NSW border. A general severe weather warning for heavy rain and dangerous surf is also current from the Capricornia to the Southeast Coast. By Wednesday rain should ease in the southeast, with showers mostly clearing further to the north. The NSW coast will then begin to feel the brunt of the low during the second half of the week.
