Cut-off low on the cards for east coast

Guy Dixon, Friday July 29, 2016 - 17:39 AEST

Southeastern Australia is in for a wooly few days next week as forecast models begin to jump on the cut-off low bandwagon.

A strong cold front is due to sweep over southeastern Australia early next week generating strong winds, widespread rainfall and a significant drop in temperatures.

Tuesday looks to be the day of most noticeable change, with a drop of 4-7 degrees across the nation's east in comparison to the previous day, accompanied by strong winds and widespread rainfall.

Eastern and northern parts of Victoria and southwestern parts of New South Wales look to collect the most significant rainfall totals on Monday as the front approaches, where upwards of 50mm have the potential to fall.

As the system traverses east on Tuesday, up to 30mm may collect over southern and eastern parts of NSW and eastern VIC.

It's at this stage where things have the potential to get interesting with increasing model consensus of a developing cut-off low over the Tasman Sea.

In this instance, we could be in for a run of prolonged wet and windy conditions along the eastern seaboard, accompanied by an increase in swell. At this stage, the centre of the low looks to be positioned off the Eden Coast, placing the main swell generating fetches over land.

As a result, the initial outlook of a strong southerly groundswell looks limited, however these systems are notoriously dynamic and if this low were to be positioned a few hundred kilometres further east, swell generation could be rapid.
