Six new automated pollen counters will be part of an expanded and more sophisticated thunderstorm asthma risk forecasting system in 2025, aimed at keeping Victorians safer this grass pollen season.
Health Minister Mary-Anne Thomas visited the State Control Centre to encourage Victorians to be prepared by using Victoria’s Epidemic Thunderstorm Asthma Risk Forecast System, now available online until December 31.
“We want everyone to stay safe this pollen season, and with these high-tech upgrades, more Victorians can now stay informed and put their asthma action plans in place on high risk days,” she said.
Replacing manual traps, the new automated pollen counters use advanced imaging to deliver faster and more accurate data – giving Victoria a nation leading tool to strengthen forecasting and health alerts.
Providing a three-day forecast for Victoria’s nine weather districts, the system will indicate a low, moderate or high risk, alerting people when they should avoid exposure outdoors to reduce demand on emergency services.
Thunderstorm asthma usually occurs between October and December when certain thunderstorms cause grass pollen grains to burst into tiny particles, which can be inhaled deep into the lungs and trigger asthma symptoms.
Those most at risk are encouraged to take any prescribed medication, follow their asthma action plan and be alert on higher-risk forecast days – closing windows and avoiding outdoor exposure during wind gusts and storms.
“People with asthma or hay fever can reduce their risk by avoiding being outdoors during thunderstorms, particularly the wind gusts that come before them. Check the VicEmergency app and plan ahead,” Victorian Chief Health Officer Caroline McElnay said.
The launch of the forecast system in 2017 followed the world’s largest epidemic thunderstorm asthma event in Melbourne on 21 November 2016, that tragically resulted in 10 deaths and thousands of people developing breathing difficulties in a very short time.
The new pollen counters are part of a joint investment with the state government investing $2.97 million to deliver the modernised system – supported by a $2.4 million contribution from the federal government through the Disaster Ready Fund which includes funding for a further three pollen counters in ACT, NSW and SA.
