Australia’s first major heatwave of the summer is here, and it’s set to be a scorcher, with temperatures set to top 40C in quite a few spots across the country. The Bureau of Meteorology has issued a 3-day heatwave warning, with South Australia and NSW expected to cop the worst of it. But before you start thinking it’s record-breaking stuff, senior meteorologist Dean Narramore says it’s actually not that unusual. Meanwhile, if you’re living on the Queensland coast, it’s time to dust off your cyclone plan with Tropical Cyclone Jasper brewing off the coast of the Solomon Islands. It’s expected to ramp up to a Category 4 tomorrow (which is strong…), and could impact the not-so Sunshine State next week. The Bureau reckons the region “north of Mackay” is most likely to feel the brunt – but it’s still too early to know precisely where Jasper will go.
