Advertisement Emergency services are bracing for this seasonâs âmost challengingâ fire risk over the next 24 hours as a heatwave moves across Victoria and sends temperatures soaring past 40 degrees. Melbourne is expected to swelter through an âoppressiveâ Sunday night, with temperatures not likely to dip below 27 degrees and then increasing to the 30s by mid-Monday morning, prompting a warning from Emergency Management Victoria about the fire danger, the âsignificantâ increase in drownings this year and heat-related illnesses. Emergency Management Commissioner Andrew Crisp says emergency services are well prepared for this yearâs bushfire season.
