Temperatures in New Zealand are about to hit summer-like levels thanks to a heatwave in Australia.

We saw a slight jump in temperatures this week across northern New Zealand as the first wave of warmer air from Australia brushed Northland and, overnight, Auckland.  

However tomorrow and this weekend temperatures are set to rocket  above 30 for some as a large high moves into the northern Tasman Sea and feeds hot nor’westers over both islands.

Temperatures in Gisborne and inland Hawkes Bay are very likely to hit the low 30s while Napier, Hawkes Bay and Wairarapa reach the late 20s.

Inland parts of Canterbury are likely to climb into the late 20s with mid-20s expected near the coast. 

Even Southland, which has had a wintry run of weather so far this month, is likely to reach the mid 20s during Friday.

Winds are also likely to be strong in exposed places with gales possible around Cook Strait.

Temperatures reach the Mid-40s in Australia

Vast tracts of South Australia are this morning preparing for another baking day of catastrophic fire risk after authorities closed schools, advised people to leave danger zones and called in water-bombing aircraft during yesterday’s 40C-plus temperatures.

Fires did break out in the tinder-dry country around Coober Pedy and Roxby Downs to the remote northeast of Adelaide, and in country between the Flinders Ranges and Port Augusta, but by late afternoon they had been contained.

The risk is that as temperatures again soar into the mid-40s today, fires that do erupt will rage out of control, threatening lives and destroying anything in their path as they are driven by hot, strong winds.

Conditions were worse yesterday than predicted, with the fire danger rating in the Flinders and northwest pastoral districts peaking well above the trigger level for the catastrophic rating.

This is the first time the rating – devised after February’s Black Saturday fires in Victoria – has been used, and warns of conditions every bit as bad as those that killed 173 people and destroyed entire towns.

The rating warns that any fires are likely to be fast-moving, uncontrollable, unpredictable and likely to kill anyone in their paths.

Fire authorities advised people to evacuate if they were not well-prepared for a potentially disastrous fire, and to ensure that the elderly left early.

Country Fire Service deputy chief officer Andrew Lawson said outbreaks were likely to develop “very, very quickly”, throwing flames ahead of the main front.

“They will be very, very dangerous fires.”

CFS strategic services manager Mick Ayre told ABC radio that the best advice fire authorities could give was to think carefully about the ability to fight a fire in catastrophic conditions.

“If you’re not comfortable and if you don’t have the right equipment and if your property is not prepared, it’s better to go and do something else like go to the beach or the shopping centre than it is to take the risk of defending your property or escaping at the last minute,” he said.

“If you decide to stay, you could die in the attempt to save your property.”

Education officials closed 11 schools yesterday as a precaution, and police began monitoring known firebugs as the mercury climbed.

As the state sweltered in temperatures that reached 44C in some areas, Adelaide endured a peak of 41C, following its first recorded official November heatwave last week.
