Then we’re up and running again, as another day of widespread storm activity is expected over eastern Australia.

Forecasters have predicted that today will be the biggest stormy day of this cycle, focusing on northern New South Wales and southeastern Queensland.

So be prepared for delays if you are trying to watch cricket.

“It’s really another week and another potentially heavy rainfall event for eastern Australia, which is very much in line with the current La Niña pattern at the moment,” said the Bureau of Meteorology’s Jonathan How.

“For Brisbane, there is a risk of potentially severe thunderstorms.”

Heavy hail, damaging gusts of wind and heavy bouts of heavy rainfall are all on the map, but are not expected to be quite as extreme as the recent ones.

By adding depth to this order, a top-level low is expected to help push a low over NSW late today.

“So apart from general showers and thunderstorms across the east coast, we are likely to see some areas with heavy rainfall develop,” said Mr. How.

As the low point moves out into the Tasman Sea on Thursday, it is expected to direct a moist, easterly current across southern NSW and eastern Victoria.

But the location of the heaviest falls will depend on where the low moves.

“The guide for computer models is still a bit divergent at this stage, but it does suggest that the focus area will be south of Sydney, around the south coast and down towards Victoria,” How said.

According to the forecast, Gippsland may be in the firing line, and heavy rain may push as far inland as Canberra.

With the rain comes the floods

Mr. How said with the expected rainfall, some renewed hikes and potentially some lightning floods would occur along the coast.

Systems that have already experienced major floods, such as Lachlan, expect more rain this week.

“We have lots of warnings of moderate to severe flooding across several catchments, and it will pretty much stay that way for the next few days, if not weeks, even probably months,” How said.

Dangerous conditions are also expected to develop along the coast, pushing up to Sydney on Thursday and into Friday.

Precipitation shortages over

Finally, after years of red, the drought map is a sight for sore eyes with only a small part of the country still having a deficit of rainfall over a 20-month period.

Even those parts of Queensland that stubbornly avoided the rain last year have caught up with what has been the country’s wettest November ever.

“Even though we were in La Niña last summer, Wide Bay and Capricornia really missed the rain. But this year they have been really hit hard,” said Mr. How.

“It has actually been enough to reverse some of these rainfall deficiencies across the southern, southeastern parts of Queensland.”

The rain has been devastating for some, but Australia as a whole is currently heading for a record crop this season.

Warm in the west and north

While the East has been soaked, the West has baked.

“Severe to extreme heat conditions have largely just gripped northern Australia with consecutive days in the high 30s (degrees Celsius) to low 40s,” said Mr. How.

Port Hedland has for the first time recorded six days in a row above 43 degrees Celsius; impressive readings dating back to 1942.

The heat is attributed to an unusual lack of sea breeze.

Nearby, the Marble Bar has already broken 46C.

Fortunately, showers and storms are expected to increase over the next few days, bringing some relief.

Although it is not quite officially the monsoon yet, monsoon-like conditions are expected to occur later in the week and into next week.

The monsoon bottom is currently lurking up over Indonesia and is expected to move down earlier than usual, ensuring a steamy La Niña summer.
