The Bureau of Meteorology issued a Flood Watch for Mid North Coast, Hunter and parts of Sydney - including Hawkesbury - on Thursday afternoon and Hawkesbury SES has asked residents to prepare for floods this weekend.
The NSW SES Hawkesbury Unit posted on Facebook last night:
"TIME TO GET READY
"A flood watch has been issued for the Hawkesbury, Colo and Macdonald Rivers.
"Depending on how much rain we get on Saturday will determine the level of flooding - minor to moderate.
"If you live in low lying areas or in close proximity to these rivers, tomorrow [Friday] is a good day to get ready, by relocating pumps, horses and livestock to higher ground."
Catchments likely to be affected by flooding are currently wet following rainfall earlier in the week, according to the Bureau.
For information this weekend, residents are advised to keep tabs on the Bureau of Meteorology website.

A Flood Watch means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop.
Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service.
Severe Weather Warnings will be issued or updated if very heavy rain is forecast or observed.
