Deniliquin evacuates ahead of major flooding with severe weather warnings across NSW

A severe weather warning has been issued for much of New South Wales as another evacuation was ordered in a flood-affected Riverina town.

The State Emergency Services asked people in Deniliquin to leave their homes by Wednesday.

Damaging westerly winds averaging 50km/h to 70km/h with peak gusts in excess of 90km/h are likely across elevated parts and also eastwards to the coast and across the Goulburn region.

Showers or thunderstorms are also predicted across the Riverina and south-west slopes.

In the 24 hours to Monday morning, the SES received 617 calls for help and conducted three flood rescues.

There are 102 warnings in place in the state, 16 of which are at emergency level.

The SES said it was focused on Forbes, Condobolin, Euabalong, Eugowra, Walgett, Bourke, Hay, Albury, Echuca, Mildura, Wentworth, Deniliquin, Wee Waa and Moulamein.

Many of the calls for help on the weekend were in response to damage caused by high winds, including roofs flying off, and fallen trees and powerlines.

Bom meteorologist Jonathan How said the cold and windy conditions were unusual late in spring and warned people to listen to warnings and stay away from trees.

The flood risk remains in central western towns but no significant rain was expected in saturated catchments this week.

In Forbes moderate flooding continues but the real concern this week is downstream at Condobolin, where the Lachlan River is expected to peak on Wednesday.

The NSW emergency services minister, Steph Cooke, said nine recovery assistance points were opening this week to support communities.

The multi-agency hubs are designed to help flood-affected individuals, families, farmers and business owners begin the clean-up, rebuilding and recovery process.

Staff will help people replace damaged documents, get help with the clean-up or access emergency accommodation or mental health services.

The nine recovery assistance points operating this week include Eugowra, Orange, Parkes, Gunnedah, Cudal, Wagga Wagga, Narrabri and Moree.

Lawyers are also joining efforts to give residents a helping hand with at least 10 law firms in the central west providing pro-bono flood recovery support.
