Even though the La Nina weather trend was officially over last week, an east coast low has brought back persistent rain, flood warnings, and evacuation orders.
The most recent flooding in NSW came while some homeowners are still getting over several other recent floods.
The weather in June, according to Weatherzone meteorologist Joel Pippard, was primarily brought on by an increase in westerly winds, which are typically relatively dry because not many storm systems pass through that direction.
So, he said, “we started to see more cold fronts come through, which is very common over winter.”
In addition to being an east coast low, according to Mr. Pippard, “You could also call it a cloud bend because it was all related.”
This cloud “went all the way up through Queensland and up to Papua New Guinea,” and the upcoming weeks or possibly months will not bring much sunshine.
The winds have changed again to an easterly direction, so they are once more coming in off the ocean, which has brought the rain and destruction back.
The major weather events we’ve experienced so far this year have all come from the east, and this one is no exception, according to Mr. Pippard.
Last week, the La Nina finally collapsed.
It usually breaks down around March or April, so the fact that it took until the end of June to do so is extremely late.
“When that occurs, you still have La Nina’s leftover effects, which are the warm waters towards the east coast.”
The rain will continue to fall, according to Mr. Pippard, who also noted that there is no difference between a climate prognosis and a weather event.
It’s possible that we’ll have a brief period of sunshine on Wednesday and possibly on Saturday. However, next Monday might be the next day that is actually dry,’ he said.
“It appears likely that showers will continue at least over the upcoming week.”
Mr. Pippard has terrible news for those wishing to dry their sheets on a laundry line. Stick to the dryer, or try your best, he said.
Flooding is the biggest worry in the coming days, even though the worst rain from the wet weather event has already poured throughout Sydney, according to forecasts.
71 evacuation orders have been issued, and 30 areas are in danger of flooding as a result of the continued deluge that is battering NSW, which is experiencing the worst flooding in the past 18 soggy months.
The most recent areas to get evacuation orders were Wallacia Caravan Park, portions of Emu Plains, parts of Penrith, portions of Lower Portland, Pitt Town, Agnes Banks, and South Maroota.
A total of 64 further evacuation advisories had been issued, and more than 32,000 residents of the state had already been encouraged to leave their homes. An additional 6,000 people were advised to be vigilant and prepared to flee.
The majority of the remaining year may see rain.
‘Even if the climatic drivers suggest that it would be drier, there is a possibility that we could receive more big amounts of rain if we get a system where winds start to come from the east again,’ he said.
Even the possibility of a future La Nina exists.
Already, there has been a double La Nina. Both the summer before and the summer before that, we had one.
“If we’re entering another one in the upcoming summer, it would be a third in a row,” she said.
Even if there have been only two occasions in the past 100 years when there have been three La Ninas in a row, it is still extremely unusual.
La Nina technically occurs in the spring, but because July is typically the wettest season, it has the most impact.
“These rivers are rising far more quickly than expected,” we are told. Much quickly than we anticipated,’ he said on Monday, according to the Nine Network.
“Things are moving more quickly. The danger has considerably escalated.
Some homeowners are still getting their homes back in order after the most recent flooding in NSW.
According to the most recent information available, Murray Watt, the federal emergency management minister, told ABC Radio that there is a very strong probability the flooding will be worse than any of the other three floods that those areas have seen in the last 18 months.
Another concerning part of this is that there are locations in the region that haven’t flooded in the past 18 months or so but may very well flood this time.
Mr. Watt stated that he anticipated the latest flooding to be officially classified as a “disaster” by the NSW state government.
“We anticipate that happening fairly soon, and that will result in a whole range of support from the federal and state governments,” he said.
Everything, including further counseling support and disaster payouts. However, as I said, I assure the public that both the federal and state governments are acutely aware of their suffering, and we will support them as they move forward in their efforts to recover.
