The warning covers eastern and northern Victoria, including Shepparton and Bendigo.
A major thunderstorm asthma event in November 2016 resulted in 10 deaths.

Why it matters

The issuance of this warning reflects a sophisticated public health response developed after the 2016 crisis. By combining meteorological forecasting with pollen count data, the Victorian Department of Health aims to reduce the surge in emergency department presentations that characterizes these specific weather events.

A thunderstorm asthma warning has been issued for large parts of eastern and northern Victoria, as authorities urge residents to prepare for potential breathing difficulties. As of October 31, 2026, the state's health department is monitoring high grass-pollen levels combined with forecast storm activity that could trigger severe symptoms.

Why it is trending now

The alert was triggered by a forecast from the Bureau of Meteorology indicating that a low-pressure system is expected to move across eastern Victoria throughout the afternoon and evening. Chief Health Officer Caroline McElnay noted that high winds associated with these storms can break grass pollen into smaller particles, allowing them to penetrate deep into the lungs and cause asthma attacks in susceptible individuals.

Key facts

The warning specifically covers all three Gippsland districts and the Northern Country region, including Shepparton, Bendigo, Inglewood, Echuca, and Euroa, according to VicEmergency.
Residents are advised to carry their asthma reliever puffers at all times, according to the Department of Health.
Health authorities recommend turning off evaporative air conditioners that draw air from outside and staying indoors with windows and doors closed during the event, as reported by the Bendigo Advertiser.
Symptoms to monitor include wheezing, breathlessness, chest tightness, and persistent coughing, according to Chief Health Officer Caroline McElnay.

Why this is trending in Australia

This alert is trending because it affects a significant portion of regional Victoria, an area where residents are particularly sensitive to the historical impact of thunderstorm asthma events. The heightened awareness stems from the state's experience in November 2016, when a similar weather pattern led to a major public health emergency.

Background and context

Thunderstorm asthma occurs when specific weather conditions coincide with high counts of grass pollen in the atmosphere. The phenomenon is distinct from standard asthma triggers because the storm's wind currents concentrate and fragment pollen, which can cause rapid onset of symptoms even in people who may not have a history of chronic asthma. Past events have demonstrated that these conditions can overwhelm emergency services, leading to the current proactive warning system used by the Victorian government.

What happens next

Residents in the affected regions are advised to remain vigilant as the weather system moves through their areas today. Official health advice is to follow asthma action plans and seek medical assistance if symptoms do not improve after using a reliever puffer. Further updates will be provided by VicEmergency if the risk level changes as the storms develop.

Frequently asked questions

What is thunderstorm asthma?

It is a condition where high concentrations of grass pollen are fragmented by high winds during a thunderstorm. These small particles can enter the lungs, potentially triggering severe asthma symptoms or attacks in people with asthma or hay fever.

Which areas are affected by the warning?

The warning covers parts of eastern and northern Victoria. This includes all three Gippsland districts and the Northern Country region, which encompasses cities and towns such as Shepparton, Bendigo, Inglewood, Echuca, and Euroa.

What should I do if I am in an affected area?

Authorities advise carrying your asthma reliever puffer at all times. If a storm approaches, stay inside, close windows and doors, and turn off air conditioners that bring outside air into your home, such as evaporative cooling systems.

Who is at risk?

People who suffer from asthma or hay fever are at the highest risk. Health officials urge anyone experiencing symptoms like wheezing, persistent coughing, or chest tightness to act immediately according to their personal asthma action plan.

Is the risk confirmed for the entire state?

No. The warning is specific to eastern and northern Victoria. Other parts of the state may not be under the same high-risk alert, though residents should always monitor local updates from VicEmergency for the most current information.

When does the risk end?

The risk is associated with the movement of the low-pressure system across the region today. Once the storm passes and the weather conditions stabilize, the immediate threat of thunderstorm asthma typically subsides.
