MELBOURNE, OCT 9 (REUTERS) – A fast‑moving thunderstorm is set to sweep across Victoria today, reviving concerns of “thunderstorm asthma” that claimed dozens of lives in 2016. The Bureau of Meteorology (BoM) has issued a red alert for pollen‑laden gusts, while health officials urge vulnerable residents to prepare.

Thunderstorm Asthma Risk in Victoria

- **What:** Thunderstorm asthma occurs when high humidity and strong winds rupture pollen grains, creating respirable particles that trigger asthma attacks. - **Who:** Approximately 1.2 million Victorians have diagnosed asthma; 30 % are classified as high‑risk. - **When:** The storm is forecast to hit the Melbourne metro area between 14:00‑18:00 AEST. - **Why:** BoM data shows a 250 % rise in grass pollen compared with the five‑year average. - **How:** Emergency departments in the city have pre‑positioned staff and stocked extra bronchodilators.

Historical Context of the 2016 Event

The 2016 thunderstorm asthma episode remains Australia’s deadliest non‑communicable‑disease disaster. On Nov. 21, 2016, a similar storm overwhelmed hospitals, resulting in 9 deaths and over 9,000 emergency presentations.

Parameter	2016 Event	2026 Forecast	Recommendation
Pollen Concentration (grains/m³)	45,000	180,000 (projected)	Stay indoors, use HEPA filters
Hospital Admissions (first 12 h)	9,000+	12,000+ (model)	Activate emergency protocols
Mortality	9	5‑7 (expected)	Prioritize high‑risk patients

Current Meteorological Data

The BoM’s high‑resolution radar shows a squall line moving eastward at 45 km/h, with relative humidity spiking to 78 % and temperature holding steady at 22 °C. The pollen forecast, supplied by the Australian Pollen Database, lists ryegrass as the dominant allergen, accounting for 62 % of airborne particles.

Health Authority Response

Victoria’s Department of Health has launched a multi‑channel alert: SMS, radio, and social‑media messages. Dr. Lena Hart, chief medical officer, said, “We have mobilized 150 extra paramedics and stocked 20,000 extra inhalers in regional pharmacies.” The state also advises schools to keep windows closed and to postpone outdoor physical education.

Outlook and Official Statements

Meteorologists expect the storm to weaken after 18:00, but residual humidity may sustain elevated pollen levels into the night. Officials plan a post‑event review to refine early‑warning algorithms. Residents are urged to follow the Health Department’s “Asthma Safe Night” checklist, available on the government portal.

Frequently Asked Questions

What symptoms indicate a thunderstorm asthma attack?

Sudden wheezing, tight chest, and coughing that do not improve with a rescue inhaler signal an attack and require immediate medical attention.

How can I protect my home during a thunderstorm asthma event?

Keep windows and doors shut, use air‑conditioners on recirculate mode, and run a HEPA filter if available.

Where can I find real‑time pollen and weather alerts in Victoria?

The BoM app, the Victorian Health Department website, and the “Asthma Alert” SMS service provide live updates.
