Each of these lows does have a chance of becoming a tropical cyclone, and so we'll have a closer look at each of these systems in more detail.
Keeping in mind though that the forecasts you see here are just one computer model forecast scenario. Our forecasters look at a broad range of models when producing forecasts, including the Tropical Cyclone 7 Day Outlook.
Broadly across northern Australia we see a lot of cloud on Tuesday afternoon.
We have seen four tropical lows developing, each with a unique identifier: 28U and 30U in the west, 31U in the Gulf of Carpentaria and 29U over the Coral Sea.
All four lows may or may not become tropical cyclones, but the next four names on our list are Narelle, Oran, Peta and Riordan.
Starting in the east with 29U - as of Tuesday afternoon it's currently sitting around 700 km off the coast of Cairns.
Looking at the forecast model, we see this low pressure system deepening as we head into Tuesday night and Wednesday, gradually inching towards the coast. Showers and winds will pick up across the tropical north-east coast.
By Thursday morning there is expected to be a 25 to 30 % (moderate) chance of the system becoming a tropical cyclone.
Heading into Thursday and Friday, the system gradually moves towards the Queensland coast. This means it will have less time to strengthen further.
At this stage we expect the system to cross the coast during Friday somewhere between Cooktown and Cardwell.
Regardless of whether it crosses as a tropical low or tropical cyclone, we are still expecting increasing winds wrapping into the low as well as heavy rainfall.
Beyond this, as we head into the weekend, there are a range of possible scenarios.
Most models keep the system over northern Queensland and move it towards the north-west of the state. Some models bring it further south, hugging the coast. That could bring heavy falls down to central and even south-east Queensland.
Much of Queensland has had very heavy rainfall recently, so any additional rainfall could produce renewed flooding.
If you are across northern and eastern Queensland, do keep an eye on the latest forecast updates in the coming days.
Moving west now to the Gulf of Carpentaria, we have 31U currently sitting over the water.
Over the next few days this system will gradually move around the Gulf, before starting to track towards the south-west coast and the Northern Territory.
As we head into Wednesday night, it has a low chance of becoming a tropical cyclone.
During the second half of the week we expect this low to continue moving west, bringing heavy rainfall to the Carpentaria District and parts of the Top End.
These areas have experienced widespread flooding recently.
The system is expected to move a little further north heading into the weekend, and places like Darwin could see increased rainfall.
Finally, moving out towards the west and the Indian Ocean, we have Tropical Low 28U to the south of Indonesia and 30U over the Kimberley in Western Australia.
In the forecast models, 30U gradually moves over the Kimberley coast, bringing heavy rainfall to Broome and widespread showers and thunderstorms.
The system south of Indonesia will gradually move towards the east.
By Wednesday night, the northern system has a high chance of becoming a tropical cyclone and track maps are already being issued.
The southern system has a low to moderate chance of becoming a tropical cyclone during the second part of the week.
By Thursday the systems begin to interact and rotate around each other - a process known as the Fujiwhara effect.
The southern system gradually grows at the expense of the northern one.
By Friday, the southern system becomes dominant, while the other weakens.
At this stage, neither system is expected to impact the Australian mainland or offshore territories.
If you are across northern Australia, keep up to date with the latest forecasts and warnings.
If you are in tropical cyclone areas, begin making the necessary preparations for yourself and your family.
