Eastern NSW is currently experiencing a very wet spell with rain this morning making the return to school an agonising task for parents and kids alike in the heavy traffic jams. This heavy rain has come about as moist southerly winds feed moisture to a broad trough over eastern NSW. Over the past 24 hours, heavy rainfall drowned Australia Day celebrations across eastern NSW despite spirits being kept high. The heaviest rainfall was observed over the Mid North Coast from Seal Rock to Wooli with widespread totals ranging from 50-100mm leading to extensive flooding across the region. Some areas like Sawtell and Port Macquarie Airport registered 157mm and 166mm respectively. For Port, this is its wettest January day since records began 18 years ago. The cumulatively total so far for this month is 411mm to 9am this morning (149mm is its January average), also making it its wettest January. Further south, Sydney saw 33mm of rainfall to 9am this morning, its wettest day since mid-October. In the Emerald City, the heaviest rainfall was observed over the eastern Suburbs and northern Beaches, with Randwick picking up 50mm and 58mm in Castle Cove. Further west, rainfall totals were more modest ranging from 21mm in Parramata to 6mm in Penrith. The constant rain and showers will continue through most of today along the NSW coasts, north of the Wollongong and gradually ease overnight into tomorrow morning. The mighty sun, will then timidly poach through the cloud cover tomorrow afternoon before making a grandiose comeback on Thursday.
