ADVICE TO THE PUBLIC:
MAJOR FLOODING EXPECTED AT NITMILUK CENTRE LATE TUESDAY EVENING, MAY PEAK NEAR 7.7 METRES LATE WEDNESDAY MORNING
MAJOR FLOODING POSSIBLE AT KATHERINE BRIDGE FROM WEDNESDAY 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. Along the Katherine River at Nitmiluk, river levels peaked above the moderate flood level overnight Monday due to combined flows from Seventeen Mile Creek and the Upper Katherine River at Birdie Creek. Renewed rises and a second larger flood peak were observed at Birdie Creek during Tuesday morning. As the flows from this second flood peak travel downstream, further rises through the major flood level are expected at Nitmiluk late Tuesday evening, with a major peak expected late Wednesday morning.
Downstream at Katherine Bridge, minor flooding is expected overnight Tuesday into Wednesday, with rises expected to continue through the moderate flood level early Wednesday morning. The river level may exceed the major flood level Wednesday afternoon. Peak forecasts for Katherine Bridge will be provided after a peak is observed at Nitmiluk Centre.
Further showers and thunderstorms are possible over the next few days and further river level rises are possible. This situation will be closely monitored and this warning will be updated as required.
A Flood Watch is current for parts of the Top End.
