Parts of the Illawarra could experience strong winds and heavy rain with the potential of flash flooding on Wednesday and Thursday.
The Bureau of Meteorolgy issued a severe weather warning for the coast on Wednesday morning, predicting thunderstorms to begin on Wednesday and strong winds for the Illawarra coast on Thursday.
"A trough lies along the NSW coast, with a low pressure system forecast to develop along the trough off the north coast during the course of Wednesday," the Bureau website stated.
"An approaching cold front about the south coast will then bring a second period of possibly enhanced rainfall on Thursday.
"Heavy rainfall, which may lead to flash flooding, is expected to continue during Wednesday over the South Coast, Illawarra and adjacent ranges."
It's expected the rain will ease Wednesday evening before ramping up again on Thursday during the day.
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.
