A fast-moving supercell brought golf ball-sized hail and 113 km/h winds to Brooks, Alberta, toppling power lines, damaging homes, vehicles and crops, and killing two animals at a local fun farm. Cleanup continued Thursday as highways were disrupted and about 1,000 customers remained without power.

Over 400 lightning strikes were recorded in a powerful thunderstorm across southwest Iceland, with roughly half on land and heavy rainfall of 10–15 mm per hour.

Network Rail Scotland warns that some of the 10,000 lightning strikes across the north of Scotland on 14 August damaged signalling on the Highland Main Line between Inverness and Perth, causing delays of up to 35 minutes.
