Severe Thunderstorm Warning

for LARGE HAILSTONES and HEAVY RAINFALL

For people in Metropolitan, Illawarra and parts of South Coast and Southern Tablelands Forecast Districts.

Issued at 10:23 pm Tuesday, 5 January 2021.

Severe thunderstorms are likely to produce large hailstones and heavy rainfall that may lead to flash flooding in the warning area over the next several hours. Locations which may be affected include Gosford, Sydney, Parramatta, Wollongong, Nowra and Bowral.

Severe thunderstorms are no longer occurring in the Snowy Mountains district and the warning for this district is CANCELLED.

The State Emergency Service advises that people should:

* Keep clear of creeks and storm drains. 
* Don’t walk, ride your bike or drive through flood water. 
* 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. 
* Unplug computers and appliances. 
* Avoid using the phone during the storm. 
* Stay indoors away from windows, and keep children and pets indoors as well. 
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
