NSW Severe Storms: Giant Hail and Destructive Winds Forecast 2026

Severe supercell thunderstorms with the potential for giant hail and destructive winds are forecast for parts of New South Wales, as volatile weather continues to batter Australia's east coast. The Bureau of Meteorology warns that Sunday could be "another big storm day," with very dangerous and severe thunderstorms likely for north-eastern NSW.

Storms already dumped heavy rain across large parts of northern and eastern NSW and much of Queensland on Saturday. Wind gusts reached up to 98km/h in Goulburn, and rainfall totals of between 30mm and 50mm were recorded in the Coffs Harbour area.

What Happened: Supercell Threat and Lightning Strike

On Saturday afternoon, a man in his 20s was struck by lightning while swimming at Ettalong beach on the Central Coast. Fellow swimmers pulled him from the water, and first responders administered CPR until NSW Ambulance paramedics arrived.

The man was taken to Gosford hospital in a serious condition and later transferred to Royal North Shore hospital. By Sunday morning, he was in a critical but stable condition, according to a hospital spokesperson.

Witnesses reported that while storm activity was visible in the distance towards Gosford, the area around the beach was clear and sunny. They said the lightning bolt appeared to come "out of nowhere." This serves as a reminder that lightning can strike up to 30km from the centre of a storm cell.

Why It Matters: Destructive Winds and Giant Hail

The forecast of supercell thunderstorms is particularly concerning because these storms are capable of producing giant hail and destructive winds. Supercells are the most dangerous type of thunderstorm, often lasting for hours and spawning tornadoes.

Sarah Scully, senior meteorologist at the Bureau of Meteorology, described Sunday as "another big storm day" with "very dangerous and severe thunderstorms" likely. Residents in affected areas should be prepared for potential property damage and power outages.

The wild weather is part of a broader pattern affecting eastern Australia, with volatile conditions expected to continue over the weekend. Authorities urge people to stay indoors during storms and avoid unnecessary travel.
