 Asthma Australia is urging people with asthma and hay fever (allergic rhinitis) living in the Wimmera District and surrounds to be on high alert following an Epidemic Thunderstorm Asthma warning  issued for Thursday 10 November by the Victorian Chief Health Officer.  

Avoid exposure by staying inside with windows and doors closed before, during and after the storm has passed and have asthma reliever medication on hand.  

Local Government Areas in the Mallee and Wimmera District include: 

  • Shire of Buloke 
  • Shire of Hindmarsh 
  • Rural City of Horsham 
  • Shire of Northern Grampians

  • Buloke Shire
  • Campaspe Shire
  • Central Goldfields Shire
  • City of Greater Bendigo

People at risk of an acute asthma flare-up or attack triggered by a thunderstorm include those with seasonal hay fever (with or without known asthma), asthma, a history of asthma and adults who are sensitive and have allergies to grass pollen. 

Symptoms may feel like:  

  • Sudden breathlessness 
  • Tight chest  
  • Wheezing 
  • Coughing 
  • Inability to speak in full sentences   
  • For Children – fatigue, irritability, complaining of a sore tummy, sucking in movements around chest and throat when breathing  

Symptoms can come on rapidly and must be treated immediately with an asthma reliever puffer.  


An Epidemic Thunderstorm Asthma event can result in a large number of people experiencing breathing difficulties who could escalate to severe respiratory arrest (asthma attacks) and fatality.  

To treat asthma symptoms, start Asthma First Aid immediately and call Triple Zero (000) for help if symptoms do not get any better or if they start to get worse.

Thunderstorm asthma events are triggered by an uncommon combination of high grass pollen levels and a certain type of thunderstorm, causing pollen grains from grasses to be swept up in the wind and carried long distances. 

Some pollens can burst open and release tiny particles that are concentrated in the wind just before the thunderstorm. These small particles can get deep into the airways and trigger asthma symptoms.
