A low pressure trough lying along the southern and central New South Wales coast is gradually weakening, but still bringing persistent rain, windy conditions and large waves to parts of the far southeast through Monday. In addition, King Tides are again expected along the entire New South Wales coast for Tuesday morning.
HEAVY RAIN, which may cause FLASH FLOODING and RIVERINE FLOODING, is possible for the southern parts of the South Coast and Monaro Country this morning and early afternoon, easing later this afternoon.
DAMAGING WINDS averaging 60 to 70 km/h, with gusts in excess 90 km/h, are possible along the coastal fringe south of Batemans Bay. These winds are expected to ease during this afternoon and evening as the trough weakens.
DAMAGING SURF CONDITIONS, with waves exceeding 5 metres in the surf zone, may produce significant beach erosion south of Batemans Bay for areas exposed to the east. The surf conditions are expected to ease this afternoon or evening, although hazardous surf will persist into Tuesday.
ABNORMALLY HIGH TIDES are again expected on Tuesday morning's high tide for the entire New South Wales coast. Water levels on Tuesday morning's high tide may exceed the highest tide of the year.
A Flood Watch and a number of Flood Warnings have also been issued for this event. Severe Thunderstorm Warnings may also be issued.
Locations which may be affected include Ulladulla, Eden and Moruya Heads.

The State Emergency Service advises that people should:
* Move vehicles under cover or away from trees.
* Secure or put away loose items around your house, yard and balcony.
* Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
* Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
* Report fallen power lines to either Ausgrid (131 388), Endeavour Energy (131 003), Essential Energy (132 080) or Evoenergy (131 093) as shown on your power bill.
* Don't drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
* Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
