Heavy rainfall about the southwest and Sydney basin this afternoon.

Weather Situation: A trough and cold front combines with a moist and unstable airmass in southwestern parts of the state to produce severe showers and thunderstorms this afternoon. A seabreeze convergence is triggering severe thunderstorms with heavy rainfall about the Sydney basin.

Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding in the warning area over the next several hours. Locations which may be affected include Albury, Charlotte Pass, Thredbo and Corowa.

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.
* Stay indoors away from windows, and keep children and pets indoors as well.
For emergency help in flood and storms, ring the SES on 132 500.
