London, ON F1 Tornado of August 25, 1982

London - Middlesex

This tornado occurred between 3:30 am and 4:00 am on the morning of August 25, and touched down in southwest London. Cornell’s Fruit Farm on Southdale Rd West was first struck as the tornado whipped a narrow path about 15 metres wide through an apple orchard. About 2.5 km to the south, at Lot 73 on North Talbot Road in Lambeth, a cornfield also had a swath of flattened stalks. This was likely caused by either a separate unconfirmed tornado or downdraft.

14 km east of Cornell’s farm, a roaring sound was heard as the tornado struck at a farm in the hamlet of Bradley. Here, a large pine tree was snapped, and evidence of converging wind was found. It was also reported that east of London, a barn was flattened, a corn crib was blown into a field, and hydro poles were broken. It has not been confirmed as to where exactly the tornado lifted off, but it was likely in the Nilestown area.

According to Environment and Climate Change Canada (2018), an F1 tornado developed on the south side of London, ON at 4:45 am EDT and travelled for 14.9 km with a maximum width of 20 metres. The tornado caused no fatalities, injuries or property damage.
