The Gunnedah district is bracing for severe storms on Wednesday and potential minor flooding later this week.
The Bureau of Meteorology said a broad low pressure system is expected to bring widespread rainfall across parts of the state, with severe thunderstorms and local heavy falls.
NSW SES north west zone public information officer Dave Rankin said on Tuesday the river height at Gunnedah is predicted to reach 3.2 metres. This is well below the minor flood level of 7.3m and major flood height of 7.9m were breached on several occasions during last year’s successive flood events in Gunnedah.
In the Namoi region this week, the SES has been briefing volunteers about what to expect ahead of the weather system that could bring rainfall totals of between of 40-50mm and isolated bursts of up to 100-150mm in some areas.
Mr Rankin said even with preceding rain earlier this week, river catchments are still “very dry”.
He urged people to prepare early for strong winds caused by thunderstorms on Wednesday by securing loose outdoor furniture and equipment, especially trampolines.
The SES spokesman also warned flash flooding could bring sudden and unexpected changes to road conditions. He said dry creek causeways could be covered by metres of water in just a few hours after a storm event.
Those in need of assistance from storm or water inundation are urged to contact the SES on 132 500. If the situation is life-threatening, call 000.
