COASTAL LOW BRINGS DAMAGING WINDS, SURF, AND POSSIBLE HEAVY FALLS,
TO CENTRAL AND SOUTHERN PARTS OF COAST TODAY
A deep low pressure system lies off the Illawarra coast and is
expected to remain slow moving today, bringing damaging winds, rain
and large wind-driven waves along southern parts of the coast.
Conditions are forecast to ease overnight or during Tuesday morning
as the low weakens and moves east.
DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess
of 90 km/h are expected along the parts of the Illawarra and the
South Coast districts, and are likely to extend to the coastal
fringe of Sydney, and possibly the Central Coast, this
afternoon.
DAMAGING WINDS may also develop across parts of the Snowy
Mountains, Southern Tablelands, ACT, Southern Highlands and the
coastal ranges of South Coast during the afternoon.
Winds are expected to gradually ease overnight or on Tuesday
morning, as the low gradually weakens and moves east.
VERY HEAVY SURF which may lead to localised damage and coastal
erosion with wind-driven large sea waves is likely for coastal
areas south of about the Central Coast, especially in the
south-facing surf zones.
Beach conditions in these areas could be dangerous and people
should stay well away from the surf and surf exposed areas.
A Hazardous Surf Warning is also current for coastal areas between
the South Coast and Hunter Coast. See
http://www.bom.gov.au/nsw/warnings/hazardoussurf.shtml.
HEAVY RAINFALL, which may lead to FLASH FLOODING and RIVERINE
FLOODING, is also possible over parts of the Illawarra and the
South Coast districts today. Rainfall rates should ease during the
afternoon or evening, although steady rainfall will still
continue.
A Flood Warning is current for the Deua River on the South Coast.
A Flood Watch is also current for the South Coast river
catchments.
Locations which may be affected include Sydney, Wollongong, Nowra,
Batemans Bay, Eden and Cooma.

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.
