How a Storm Triggered a City-Wide Asthma Attack

In November 2016, Melbourne experienced a severe thunderstorm asthma event, causing thousands to struggle to breathe and resulting in nine deaths. Thunderstorm asthma occurs when storms concentrate pollen and allergens, triggering asthma attacks. This phenomenon is rare but may become more frequent with climate change. People with hay fever or pollen allergies are at higher risk, and emergency services may be overwhelmed during such events.
