Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding and damaging winds on January 16, the Bureau of Meteorology says.
Locations which may be affected included Batemans Bay, Nowra, Taree, Newcastle, Armidale, Orange, Canberra, Goulburn, Tamworth, Moree and Dubbo.
"Be aware that run-off from rainfall in fire-affected areas may behave differently and be more rapid," a spokesperson said.
"It may also contain debris such as ash, soil, trees and rocks.
"Trees that have been damaged by fire are likely to be more unstable and more likely to fall."
Moruya SES asked to clear downpipes and gutters.
"Gutters cleared before the fires may again be choked with fallen scorched vegetation, leaves from distressed trees, ash," a spokesperson said.
Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
The State Emergency Service advises that people should:
- Move your car under cover or away from trees.
- Secure or put away loose items around your house, yard and balcony.
