Districts.
Issued at 5:06 pm Wednesday, 3 August 2022.
Damaging winds continuing over the southeast, with heavy rainfall
possible from early Thursday.
Weather Situation: A complex low pressure system moving across the
Great Australian Bight and an associated trough and cold front are
causing vigorous northwesterly winds across southeast NSW, as well
as the potential for heavy rainfall from Thursday morning. This
front will move offshore early Friday morning.
DAMAGING WIND GUSTS with peak gusts of around 90 km/h are possible
over the ranges to the west of the ACT, as well as the eastern
Great Dividing range from Bombala to south of Crookwell, extending
north to the Blue Mountains during Thursday morning.
DAMAGING WINDS, averaging 80 to 90 km/h with peak gusts in excess
of 125 km/h are likely to continue for Alpine areas above 1900
m.
HEAVY RAINFALL which may lead to FLASH FLOODING may develop across
the Snowy Mountains and the South West Slopes from early Thursday
morning. Six-hourly rainfall totals between 45 and 60 mm are
expected, with localised falls up to 100 mm possible with embedded
shower and thunderstorm activity that may occur over shorter time
frames.
HEAVY RAINFALL which may lead to FLASH FLOODING may also develop
across the northern parts of the Central Tablelands from Thursday
afternoon. Six-hourly rainfall totals between 20 and 40 mm are
possible with localised higher falls up to around 60 mm with shower
and thunderstorm activity.
Saturated soils in the Central Tablelands and Illawarra bring an
increased risk of gusty winds toppling trees and powerlines.
A Flood Watch is current for Inland New South Wales Central and
South West Catchments. See
http://www.bom.gov.au/nsw/warnings/
Locations which may be affected include Braidwood, Goulburn,
Bombala, Tumbarumba, Tumut, Khancoban and Thredbo Top
Station.

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.
