Heavy rainfall developing about the southeast of the state on Thursday.

Weather Situation
On Thursday a low pressure system is forecast to develop and intensify along the southern and central coast in response to an upper level low. This system is expected to move out into the Tasman Sea on Saturday.
HEAVY RAINFALL for the following areas:
South Coast and Snowy Mountains
HEAVY RAINFALL which may lead to FLASH FLOODING is forecast to develop from Thursday morning over the southeast, continuing into the late evening. Rainfall is forecast to ease, but continue through Friday into Saturday morning.
Six-hourly rainfall totals between 70 to 90 mm are possible. Isolated heavier falls are also possible with thunderstorms.
A Flood Watch is current for the South Coast. See http://www.bom.gov.au/nsw/warnings/ for more information.
Locations which may be affected include Eden, Bega, Bombala, Narooma and Merimbula.

The State Emergency Service advises that people should:
* 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.

The next Severe Weather Warning will be issued by 11:00 pm AEDT Wednesday.

FLOOD WARNINGS CURRENT FOR NSW INLAND RIVERS

Renewed river level rises and flooding is possible from late Wednesday across the Upper Macintyre, Gwydir, Castlereagh, Peel, Macquarie and Belubula Rivers from rainfall associated with a deepening trough extending across inland New South Wales.
During Thursday a low pressure system will likely form along the southern and central coast. This has the potential to cause heavy rainfall and riverine flooding along the NSW South Coast, Snowy and Upper Murray and Mitta Mitta Rivers from Thursday.
Renewed river rises are also possible in the Lachlan, Namoi, Macquarie and Bogan Rivers where flood warnings are current. The situation is being closely monitored and warnings will be updated to reflect any renewed rises as the situation develops.
Catchments are wet following persistent and recurring rainfall in recent weeks.
A Flood Watch is current for widespread areas of Southern Queensland.
A Flood Watch is current in Victoria for the Gippsland, parts of the North East Victoria and the Werribee River Catchment.
