Queensland is in for a week of wild conditions, with various severe weather patterns predicted across most of the state.
The Bureau of Meteorology (BOM) has warned of possible severe thunderstorms for parts of south-east and Far North Queensland today, as firefighters try to control raging bushfires in the state's west.
BOM said severe storms were likely over northern south-east Queensland and possible for the rest of the south-east.
"We're seeing several different types of weather hazards across Queensland," senior meteorologist Laura Boekel said.
"That includes flooding, a potential tropical cyclone, heatwave, fire weather, hazardous surf and severe storms."
Sunday was the hottest day of the year in Brisbane with a top of 35.7 Celsius, but today, severe storms are predicted across the south-east.
"We could see isolated pockets of severe storms which can bring heavier rainfall, large hail as well as damaging winds," Ms Boekel said.
"We could see in excess of 50mm in Brisbane, however, some very isolated totals of up to 100mm in some areas in the south-east."
Some beaches remain closed
A hazardous surf warning also remains current across south-east Queensland due to ex-Tropical Cyclone Gabrielle, which is now a low-pressure system near New Zealand.
Numerous beaches are expected to remain closed for at least another day, with the maximum wave height recorded of about 6 metres.
Heavy rainfall may also develop across the state's far north, linked to a tropical low hovering around the Gulf of Carpentaria.
While that tropical low is now unlikely to develop into a cyclone, it could still bring damaging wind gusts, higher-than-normal tides and wet weather.
A flood watch has been issued for the Cape York Peninsula due to monsoonal activity in the area.
The BOM has warned of the potential for flash flooding in the region because water catchments are already saturated.
There is also the possibility that monsoonal activity from the tropical low could move south later in the week, with the BOM monitoring it closely.
"There is a chance that communities such as Townsville and Cairns might see higher rainfall, but we still have high uncertainty for that forecast later in the week," Ms Boekel said.
On Tuesday and Wednesday the forecast rain is expected to deliver a brief reprieve from the recent extreme heat felt across south-east Queensland.
Heat to return to south-east
Ms Boekel said Brisbane's maximums were set to remain below 30C for a few days, but the heat would return as the week went on.
"We will see some warm conditions in the morning but as that cloud builds and we see rainfall, we'll get some reprieve in the south-east, where we're seeing that activity," she said.
"However, in the south-east, that's going to pick up again later in the week, so similar conditions to what we saw over the weekend for next weekend."
It comes as firefighters continue to battle dozens of blazes in south-west Queensland, including some that have already destroyed structures and property.
Hot conditions are on track to continue in western regions, with many towns experiencing temperatures in the high 30s to early 40s, fuelling several bushfires.
Temperatures are expected to drop by a couple of degrees mid-week, offering a brief respite, before heating up again over the weekend.
A high fire danger rating will be in place throughout Queensland's southern interior on Tuesday.
