Towns on the NSW Mid North Coast have been inundated by floodwaters for the fourth time this year with the heaviest rain falling across the Bellinger Nambucca catchment. This deluge comes after 3 months of below average rain for the region. Coffs Harbour has received a month and a half's worth of rain in just a day with 147mm, making it it's wettest October day on record. Bellingen was the worst hit with a whopping 409mm in just a day! This is as much rain as places like Mt Isa, Tennant Creek and Bourke would get in an entire year! It brings Bellingen's rainfall total so far this year to over 3000mm or 3 metres! Other parts of the coast between Kempsey and the NSW/QLD border were soaked by falls of over 100mm.
A further 50-100mm is possible from Kemspey to Yamba today leading to further flash flooding and river rises. Rain will ease by tonight with showers persisting tomorrow, but drier weather will kick in from Thursday.
The reason for this huge downpour is a lingering trough over the coast which is being fed by very humid onshore winds. As this system moves to the west, conditions will ease.
Further inland, rain and storms have also been pelting north-western parts of NSW with 25mm in Cobar, it's heaviest day of rain in 4 months. Another 50mm is possibe today, especially for towns hit by storms which may be severe.
