for DAMAGING WINDS and HEAVY RAINFALL


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.

HEAVY RAIN, FLOODING AND STRONG WINDS POSSIBLE FOR THE SOUTH COAST THIS WEEKEND


A trough over the New South Wales coast is forecast to deepen a low pressure system near the southern coast on Saturday, while another low pressure system over the inland weakens. The low near the coast looks set to linger nearby during the weekend, bringing very wet and windy conditions to the southern half of the New South Wales coast and adjacent ranges.

HEAVY RAINFALL which may lead to FLASH FLOODING and RIVERINE FLOODING is possible along the South Coast and eastern parts of the Snowy Mountains and Southern Tablelands forecast districts on Saturday. Heavy rainfall is likely to continue throughout Sunday and possibly into early Monday, due to the slow movement of the low.

Embedded thunderstorm activity along the coastal fringe from Saturday may also locally enhance rainfall, leading to FLASH FLOODING.

A Flood Watch is current for the South Coast river catchments. This includes the risk of Moderate to Major flooding along the Bega River. See http://www.bom.gov.au/nsw/warnings/flood/floodwatch1.shtml for more information.

DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h, are currently occurring along the western side of Alps and are expected to ease early Saturday morning.

DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h, are also possible along the coastal fringe of the South Coast district from Saturday afternoon as a low develops nearby.

Locations which may be affected include Batemans Bay, Eden, Bega, Moruya Heads, Bombala and Cabramurra.


Cabramurra AWS recorded a 100 km/h wind gust at 3:51 pm on Friday.

The next Severe Weather Warning will be issued by 5:00 am AEST Saturday.

Flood Watch for the New South Wales South Coast and Queanbeyan River

FLOODING LIKELY FOR NSW SOUTH COAST AND QUEANBEYAN RIVER FROM SATURDAY
Rainfall associated with a Coastal Low has the potential to cause moderate to major flooding along the Bega River and minor to moderate flooding along the Moruya River. Minor flooding is possible along St Georges Basin and the Shoalhaven and Queanbeyan Rivers. Flooding is also possible in Upper Murray and Snowy Rivers. There is flood watch current for Upper Murray, Snowy, Bemm, Cann and Genoa Rivers in Victoria.

A complex low pressure system near the far northwest of New South Wales will track southeast today bringing widespread rain and windy conditions to many areas. During Saturday, the focus will shift to southeastern New South Wales as a low centre deepens offshore, bringing heavy rain to southern parts of the coast. This low looks set to linger in the region until at least Monday.
Catchments likely to be affected by flooding are currently near saturation following rainfall earlier in the previous weeks.
A Severe Weather Warning has been issued for South Coast and parts of Southern Tablelands, South West Slopes and Snowy Mountains Forecast Districts.
The weather system is expected to cause flooding for the catchments listed from Saturday. Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service. Catchments likely to be affected include: Flooding is no longer expected in the following catchments:
