The Bureau of Meteorology has reported a ridge of high pressure along the NSW coast while a trough lies over the far southwest. This trough will deepen and move towards the northeast during Wednesday as a cold front crosses to the south, bringing unsettled conditions.
During Thursday and Friday, the trough is expected to linger near the northern coast while another trough develops over the northern inland. The combination of these two systems will cause unsettled conditions in the east and north of the state for the remainder of the week and during the weekend.
Weatherzone reports said it was too early to know exactly how this dynamic weather event will unfold, which means it is not yet possible to predict where and how much rain will fall.
The Casino SES Unit said because the region already had saturated catchments, damaged roads and unstable slopes, potential further road damage and landslips were a real possibility.
