A very wet weekend ahead for NSW

14:35 AEST Rainfall is set to intensify over the weekend and early next week, with hundreds of millimetres in just three days possible across parts of the central NSW coastline.  The heavy rainfall forecast at the end of this week will follow a prolonged period of rainfall which began on Tuesday, generated by a coastal trough lingering off the NSW coast for days.  Nord’s Wharf Oval in the Hunter Valley recorded 93mm in the 24 hours leading up to 9am Wednesday, May 5.
