Homes have hit saturation point as wild weather and heavy downpours engulf millions of residences along the east coast.

Rainwater flooded homes in inner Sydney and seeped through roofs in Wollongong after three consecutive days of heavy rainfall across the central NSW coast.

At least two tornadoes were reported across the state, including one captured on camera from a fire tower at Young as it tore through a field in NSW's southwestern slopes region.

The rain continued into Thursday, with Newport on Sydney's Northern Beaches recording 122mm of rain in the day to 9am and Cronulla notching 147mm.

It made this month one of Sydney's wettest Septembers on record.

Multiple severe weather warnings remain in place, including alerts for damaging winds and hazardous surf across NSW.
