Rainfall beats annual average
Rain gauge counts for the Sunday night-Monday downpour varied, with 40.6mm falling at Coolangatta, 53mm at Murwillumbah, 71mm at Uki and 69mm at Mullumbimby.
The bulk of the rain occurred between Coolangatta and Coffs Harbour and has since moved further south and inland, according to Bureau of Meteorology forecaster Jane Golding.
“The Tweed-Murwillumbah areas missed the heavier falls that largely dominated Coffs Harbour, where 464mm was recorded in the past four days,” said Ms Golding.
“Showers will continue, remaining fairly widespread and becoming isolated, before clearing by tomorrow.”
While the weekend rain was enough to give the grass a healthy shade of green, climatologist from the Bureau of Meteorology, Agata Imielska, said to expect a drier summer season despite the higher-than-average rainfalls received already in 2009.
“We have had three larger rainfall events in the Northern Rivers area this year (April 1, May 19-23, October 27) which have pushed rainfall statistics well above the annual average,” said Ms Imielska at the New South Wales regional office.
Murwillumbah has recorded a rainfall of 1690mm to-date – 116mm more than the annual average of 1574mm.
“November to January will be drier than average and we will see warmer temperatures with the minimums and maximums,” she said.
“The conditions in the Pacific Ocean and an El Nino event are associated with these warmer temperatures, particularly for eastern NSW.
“The pattern of seasonal rainfall across south-eastern Australia is a result of recent warm conditions in both the Pacific and Indian Oceans.”
Temperatures are expected to reach 25 degrees on the Tweed today, with a chance of isolated showers in the morning and increasing sunny periods in the afternoon.Rainfall
