Attention Queenslanders – now’s when the experts want you to prepare yourselves for Tropical Cyclone Jasper. The Bureau of Meteorology reckons it could ramp up to a Category 5 storm overnight – and that’s as severe as cyclone warnings come. While it’s still 1,000km off the Aussie coast, it’s most likely to hit “anywhere between Mackay and Cooktown” early to mid-next week. Jasper could still change course, but Mackay’s mayor Greg Williamson is urging residents to get ready because “it’s too late to wake up Monday morning and have it on our doorstep”. As for the rest of the country, South Australia and Victoria will be copping the worst of the heatwave today, while NSW and the ACT will reach peak hotness on Saturday. Stay cool and safe, please…
