Flood Watch Number: 1


Rainfall associated with a Coastal Low has the potential to cause minor riverine flooding along the Shoalhaven River and St Georges Basin. Moderate flooding is possible along the Moruya and Bega Rivers from Saturday.

A complex low pressure system currently lies over northern parts of South Australia, while a weak high pressure ridge lies over the east of the state. This low will enter the far northwest this evening, and then move southeast across the remainder of the state during Friday, accompanied by wet, windy and cold conditions. During the weekend, focus will shift towards southeastern New South Wales, as the low reaches the Tasman Sea, bringing heavy rain to the South Coast.

Catchments likely to be affected by flooding are currently near saturation following rainfall earlier in the previous weeks.

The weather system is expected to cause flooding for the catchments listed from Saturday.Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.

Catchments likely to be affected include:

Shoalhaven Riverminor flooding
St Georges Basinminor flooding

Moruya and Deua Riversminor to moderate flooding
