Very heavy rain drenched the Hunter region overnight, with several places seeing their heaviest November rain on record. A small but moisture-packed east coast low approached the region overnight, bringing gusty winds and heavy, unprecedented November rain. Clarence Town copped one of the heaviest falls of the region, recording 200mm in the 24 hours to 9am today, its heaviest rain for any month since 1946 and for November on record. Nearby Dungog collected 167mm, its heaviest fall since 2009 and for November on record, while Maitland received 120mm, also its heaviest in four years. Tocal saw its heaviest November rain on record and the most for any month since 2007, being drowned with a 24 hour total of 173mm. The town is now also experiencing its wettest November on record, with already more than 200mm for the month, two and a half times the monthly average. Further south, Newcastle's Nobbys Head was swamped with 124mm, the highest fall the city has seen in six years, and heaviest for November on record. Nearby Williamtown picked up 155mm, also its heaviest November fall on record. Further rain will fall today as the low crosses the coast today and weakens, with some places likely to experience a further 50-80mm. As the low makes landfall this morning and during the early afternoon, winds reach their strongest, with warnings in place for potential gusts to 90km/h as well as flash flooding. It has been quite a turnaround for the region after experiencing a very dry and record warm winter and spring period. While the rain would be welcome, flood warnings are now in place for the Paterson and Williams Rivers. As the low dissipates overnight, conditions will ease significantly, with only a few light showers lingering on the coastal fringe until the afternoon. By Wednesday, a weak ridge of high pressure will cause sunny conditions to return. However, a low pressure trough should approach the region from Thursday, creating further unsettled weather.
