More rain falls in New South Wales, and as Australia faces the rainiest spring of the decade, more floods can occur around the state.
State emergency services have responded to 118 requests for assistance in the last 24 hours, and Flash Floods can occur with little warning, so people need to be prepared.
“The problem at this point is that it doesn’t take long to cause flash floods that can’t give many warnings to people because all dams are full, rivers are full and the ground is so saturated.” She told Sydney. Radio 2GB on Wednesday.
Massive floods have occurred along the Namoi River in Ganeda, northeastern part of the state, with fluctuating river heights reaching 8.25 meters overnight.
Further downstream, there may be moderate floods in Narrabri and large floods in Wewer later this week.
The Meteorological Department provides outlook for the rest of the week this afternoon, with additional rain threatening widespread flooding.
SES responded to multiple calls in Ganeder as Forbes Harbor in the central west and Coffs Harbor on the north coast, primarily because of windthrows and heavy rain-damaged roof leaks.
Rain continues throughout the week and is expected to fall into already soaked catchments, raising river levels and causing flash floods.
The Guidil River also swelled, causing a great flood in Yalaman.
The Macintyre River is expected to peak near major flood levels on Wednesday, although moderate floods have occurred in Goondy Windy, which crosses the Queensland border.
Moderate floods still continue at Forbes and Cottons Weirs on the Laclan River, which flooded over the weekend.
The main flood peaks pass through Gemalong, where a large flood occurred.
Floods are expected later this week in Condobolin in the central west, but moderate floods can occur in the Coonamble.
Rivers in Tamworth, Ashford and Yetman are also above small flood levels, and floods can occur in Kempsey, Singleton and Narrandera on Wednesday.
Meteorologists have declared Australia currently in the La Niña cycle, which could remain moist in the summer as well. This is a cooler, damp sister of the El Nino Southern Vibration pattern, which usually poses a rise in temperature and the danger of wildfires.
Instead, there is an increased risk of damaging tropical cyclones and floods.
During the last significant La Niña phenomenon from 2010 to 2012, extensive floods flooded New South Wales, Victoria and Queensland, as well as a Category 5 tropical cyclone, Yasi.
However, BoM does not expect this La Niña to be so bad.
Andrew Watkins, BoM Head of Operational Climate Services, said the La Niña event this summer appears to be weaker than the moderate La Niña event developed last year, but the danger remains.
“The weak La Niña phenomenon can sometimes lead to heavy rains. In moist landscapes, there is a greater risk of flooding during the summer,” Dr. Watkins said.
In New South Wales, more rain is expected for the rest of the week, and new river levels may rise.
SES has already responded to more than 6715 requests for assistance since the beginning of the stormy season last month.
