A previous one forecast by the NSW government in 2017, Penrith City, Hawkesbury City, The Hills Shire and Blacktown City said the most risk of a devastating flood, with Richmond and Windsor also in the line of fire.
& # 39; Although there has been no major flood in the Hawkesbury-Nepean Valley for more than 25 years, floods can and will happen again & # 39 ;, it said.
& # 39; Nothing can completely stop flooding in the Hawkesbury-Nepean Valley. & # 39;
The NSW government is taking a number of measures to reduce the impending disaster.
One is to increase the height of Warragamba Dam by 14 meters to temporarily stop flooding water.
Warragamba is Australia's largest urban water supply and is a 30-minute drive from Penrith.

Authorities believe that increasing the length will significantly reduce the risk to people's lives downstream.
It offers more time for evacuation and reduces flood damage by around 75 percent on average.
Stuart Ayres, minister of West Sydney, admitted that raising the dam height has environmental implications.
& # 39; Yes, we have environmental implications, we don't deny that, but this is about putting real estate and life first & # 39 ;, Ayres told Seven News.
& # 39; It's not a matter of when it will happen (floods), it's a matter of happening. & # 39;
