Severe thunderstorms have prompted multiple tornado warnings across southern Ontario, affecting areas such as Brantford, Simcoe-Delhi-Norfolk, and Woodstock-Tillsonburg-Oxford County. Environment Canada warns of possible tornadoes, destructive winds, and large hail as the storms move through. Chief meteorologist Anthony Farnell highlighted the risk of quick tornado spin-ups and reported widespread straight-line winds of 90-100 km/h. Currently, tornadoes have been confirmed over Burgessville and near Springford, with the storm system advancing east at 80 km/h. Wind gusts could reach as high as 130 km/h, and hail may be up to 2.5 centimeters in diameter. Residents in the storm's path, including Norwich, Otterville, and Princeton, are urged to seek shelter immediately in a basement or sturdy building due to the life-threatening nature of the situation. Environment Canada emphasizes that tornado warnings are issued when a thunderstorm is producing or likely to produce a tornado, and residents should stay updated on alerts and forecasts as the situation develops.
