Minor to moderate flooding possible for Hawkesbury and Colo rivers from late Saturday – BOM

Flood Watch for the Hawkesbury Nepean and Colo Rivers

Issued by Bureau of Meteorology at 1:44 pm EDT on Saturday 22 October 2022 Flood Watch Number: 6

This is a Flood Watch, not the more serious Flood Warning.

Warragamba Dam remains at 100% capacity – as it has been for over a week – so is continuing to spill.

The Bureau says in its latest alert this afternoon that minor to moderate flooding is possible for the Hawkesbury Nepean and Colo rivers by late today – Saturday.

Here’s Yarramundi Bridge at 3.05pm via the Live Traffic camera, so water level relatively normal there at the moment…

A low pressure system and trough over northwestern NSW is bringing significant rain and widespread thunderstorms during the weekend as it slowly moves east. Another system is expected to move into western New South Wales later Sunday and then move east early next week, bringing further rain and thunderstorms over the state. This rainfall may cause new and renewed flooding along rivers in parts of New South Wales Central West and South West Inland catchments from late Saturday, many of which are experiencing ongoing flooding due to previous rainfall in recent months.

This weather system is also likely to affect coastal catchments including the Wollombi Brook, Lower Hunter, Hawkesbury Nepean and Colo Rivers from late Saturday into Sunday, says BOM.
