A fast-moving severe weather system caused widespread alarm in Southern Ontario on Tuesday as red warning severe thunderstorm alerts, yellow warning severe thunderstorm advisories, tornado warning Ontario notices, and tornado watch Ontario alerts rapidly spread across London Ontario, Hamilton, Windsor, Toronto, and surrounding areas. Residents hurried to check updates from the Weather Network, weather radar maps, Environment Canada alerts, and Instant Weather Ontario feeds while violent thunderstorms brought destructive winds, funnel cloud sightings, lightning strikes, hail, and possible tornado activity.

Meteorologists warned that potential hazards included:

Possible tornadoes Damaging winds between 110 km/h and 130 km/h Quarter-sized hail Dangerous lightning Flash flooding risks Falling tree branches and debris

The situation regarding the tornado warnings in Ontario remained active into the evening before they were eventually lifted later at night as storms continued moving eastward.
