The flood warning for the Hawkesbury and Nepean rivers has been downgraded to minor after a spill from Warragamba Dam reached its peak.
Severe weather conditions caused flooding across New South Wales overnight, but the NSW State Emergency Service (SES) says flood evacuation warnings in low-lying areas of the Richmond lowlands, Pitt Town and Gronos Point have now been cancelled.
Warragamba Dam spilled at about 9pm yesterday, while flows from the Nepean River caused minor flooding in Penrith and Richmond.
SES spokeswoman Sue Pritchard is urging residents in flood-affected areas to take care on the roads.
"We're still asking people to exercise caution in those areas," she said.
"There's a lot of roads that are underwater. We've already been called out to flood rescue in the early hours of this morning and people just need to be mindful that this water will hang around for a while."
Yarramundi Bridge remains closed and Windsor bridge is expected to be closed later today.
