Heatwave to sweep east coast day after La Niña officially declared over
Less than a day after La Niña was officially declared over by the Bureau of Meteorology (BoM), fresh warnings have been issued over a sizzling heatwave set to sweep the country's east.
Temperatures will heat up today and linger above the 30 degree mark for the remainder of the week in New South Wales, which has been flagged as being "in the bullseye of the weather system", and in parts of Queensland's southeast.
The unusually long-lasting hot burst is set to see conditions swelter to almost 40 degrees in some parts of NSW over the coming five days, with Thursday and Sunday tipped to be the most uncomfortable.

The announcement has left firefighters on edge after a treacherous string of almost 300 bushfires lashed the state last week.
During last week's heatwave, some 19,000 hectares of land were burnt in NSW's Central West and hundreds of homes were in the firing line.
Today in Sydney's metro temperatures will reach 27 degrees before heating up to 33 tomorrow and 32 degrees on Sunday.
In the city's west, it'll reach 31 degrees today, 37 degrees tomorrow and 38 degrees on Sunday.

Yesterday, the bureau said that the third consecutive La Niña has officially ended, but immediately issued an El Niño watch, saying there is a 50 per cent chance the latter weather phenomenon will occur later this year."
"The El Niño–Southern Oscillation (ENSO) is now neutral (neither La Niña nor El Niño) with oceanic and atmospheric indicators having returned to neutral ENSO levels," the bureau said.
"International climate models suggest neutral ENSO conditions are likely to persist through the southern autumn.
"However, there are some signs that El Niño could form later in the year.
Elsewhere around the country, it'll be cloudy and 31 degrees with a chance of showers in Brisbane, 30 and rainy at the Gold Coast, 28 and mostly fine in Canberra, 25 degrees and sunny in Melbourne, 28 degrees and partly cloudy in Adelaide and sunny a 28 degree day in Perth.
