Flood Warning Number: 15

RENEWED RISES TO THE MAJOR FLOOD LEVEL POSSIBLE AT WINTON FOR THE REMAINDER OF MONDAY AND INTO TUESDAY

Widespread heavy rainfall late last week has caused river level rises and flooding across the Diamantina River catchment and its upper tributaries. Over the last 48 hours, further rainfall totals up to 95 mm have been observed across the Western River catchment. Renewed rises to the major flood level remain possible along the Western River at Winton as flows arrive from multiple tributaries.
