Over a month's worth of rain in the last two days has left rivers swollen in northeast New South Wales. A slow-moving low pressure trough near the coast was largely responsible for the two day deluge, which targeted the state's Northern Rivers and Mid North Coast Districts. Rainfall totals during the 48 hours to 9am today reached 304mm at Goonengerry and 271mm at Doon Doon. Ballina Airport's 181mm in this time was the site's heaviest two day total since June last year. Widespread falls of 100-150mm were observed during the last 24 hours along the coast and adjacent inland between Forster and the Queensland border. Port Macquarie Airport registered 166mm during this time, which is their heaviest rain in 10 years. Further north, Smoky Cape collected 180mm, a month's worth of rain and the heaviest for March in 43 years. Drier weather has returned to the region after the rain-bearing trough moved offshore this morning. While this has giving bulging rivers a chance to recede, minor flooding may still occur in some areas today. Showers are affecting the central and southern coasts of New South Wales today and should return to the saturated north coast from Friday. There may be further heavy falls in the state's northeast on the weekend, so keep up to date with the latest severe weather and flood warnings during coming days.
