River flooding may develop later Wednesday. Low lying bridges and causeways may be affected and become impassable.
Further rain is expected on Thursday, easing on Friday, with Sydney experiencing rain, but this rain not likely to be intense.

What the NSW SES is doing:
- The NSW SES has received 30 calls for emergency help across the Sydney Metro, Illawarra, Central Coast and Hunter Regions. These are mostly leaking roofs and minor damage.
- Flood rescue technicians have been located at SES Units near known flash flood hotspots. SES volunteers in affected areas are on standby to assist as required.
- Sandbags are available at some SES Units (Dungog, Maitland, Singleton and Newcastle City) or you can purchase at your local hardware store.
- The NSW SES has a helicopter on standby in Maitland.
What you can do:
- People who live and work in areas affected by the Flood Watch should act now to lift pumps and equipment and relocate livestock and agisted animals to higher ground.
- If isolation is likely, stock up now on food, fuel medicine and other essential items.
- Low lying roads and causeways may be affected. Plan your journey and consider alternate routes or arrangements if roads are blocked. Delay non-essential travel in heavy rain.
- If your property is affected by flash flooding, consider preparing sandbags now. These can be purchased from hardware stores. (There may be SES Units or Councils with collection points – listen to your local radio or check local SES social media).
- Clean gutters and downpipes, and ensure drains around your property are clear.
- Check your roof is in good repair.
- When heavy rain commences, park your car away from areas that might flood, never drive through floodwaters and keep your children indoors away from flooded areas. Playing in floodwater is dangerous as debris, strong currents, stormwater inlets and culverts may not be visible under floodwater.

- You can also help by being prepared and helping friends and neighbours who might need assistance, especially the elderly or those with a disability.
