Flood Warning Number: 51

MAJOR FLOODING POSSIBLE AT NITMILUK CENTRE FROM LATE TUESDAY AFTERNOON

Moderate to heavy rainfall associated with Ex-Tropical Cyclone Narelle since Sunday has caused significant river level rises along the Katherine River and its tributaries.

Renewed rises are occurring at Birdie Creek and are approaching a second larger flood peak Tuesday morning. As the flows from this second flood peak travel downstream, further rises to the major flood level are possible at Nitmiluk from late Tuesday afternoon. Downstream at Katherine Bridge, minor flooding is likely from Tuesday morning, with further rises to the moderate flood level possible from overnight Tuesday. The river level may reach the major flood level late Wednesday morning.
Further showers and thunderstorms are possible over the next few days. This situation will be closely monitored and this warning will be updated as required.
