The warning stretches as far north as Seventeen Seventy down to Caloundra. A trough with an embedded subtropical low over the central Coral Sea is forecast to deepen while moving rapidly southwest towards the Capricornia Coast on Sunday. It is then expected to adopt a south to south easterly track on Monday and move parallel to the coast, either along the coastal fringe or just offshore. The threat of heavy rainfall is highly dependent on the track of the trough and embedded subtropical low. The weather warning said the heavy rainfall may lead to flash flooding. Six-hourly rainfall totals between 120mm and 160mm are likely in some areas with locally intense falls of 200mm to 250mm possible over coastal communities and Fraser Island.
