Heavy rain impacts Sydney with flooding risks – Saturday 20 March 2021

Between 9 am and 3.30 pm Saturday, Sydney has been drenched with some areas receiving substantial rainfall totals. During this period, I managed to take some photos of rising waters at a local park in Blacktown which provides an idea what is occurring at other localities across the city.

Such scenes would be occurring within any low lying area of the city and it is identified that minor flooding is now occurring at the North Richmond Pumping Station and a moderate flood peak has passed through the Colo River at Upper Colo.

Such rain appears to be easing across northern Sydney as the bulk of the rain system continues to move further south.

For the period 9 am to 3.30 pm, the following rainfall totals have been recorded across Sydney:-

Observatory Hill - 76 mm (Since Friday morning - 124 mm cumulative total).

Bankstown - 72 mm (Since Friday morning - 126 mm cumulative total).

Manly - 68 mm (Since Friday morning - 122 mm cumulative total).

Airport (Mascot) - 64 mm (Since Friday morning - 102 mm cumulative total).

Parramatta - 52 mm (Since Friday morning - 78 mm cumulative total).

Similar other totals have occurred throughout Sydney and more rainfall is expected.
