HEAVY RAIN AND STRONG WINDS DEVELOPING ABOUT SOUTHWEST SLOPES AND RANGES ON WEDNESDAY
A strong cold front, currently over the Bight, will reach the state's west later Wednesday then move through central and eastern areas on Thursday, bringing strong winds to the Alpine region and widespread rainfall to parts of the ranges and western slopes.
For alpine areas above 1900 metres, DAMAGING WINDS, averaging 80 to 100 km/h with peak gusts in excess of 120 km/h are possible from Wednesday morning. For alpine areas above 1700 metres, DAMAGING WINDS averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are also possible.
HEAVY RAINFALL, which may lead to FLASH FLOODING, is forecast to develop over southern parts of the Southwest Slopes and adjacent ranges on Wednesday morning.
Isolated thunderstorms embedded within the rain band may locally enhance rainfall and bring DAMAGING WIND GUSTS in excess of 90 km/h.
Heavy rain and damaging winds are expected to ease a little as the front crosses the area during Thursday morning.
A Flood Watch has been issued for a number of catchments on the western slopes. A Flood Warning is also current for the Bogan River.
Locations which may be affected include Tumbarumba, Thredbo, Cabramurra, Selwyn, Tumut and Khancoban.
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.
