Today's Weather Trivia

22 October

2004: A significant weather system north of Lake Superior soaked the region around Nipigon and Red Rock, ON, with 75 to 100 mm of rain, which damaged major highways and roads, forcing officials to close 4 sections of Highway 17. CP Rail also worked to repair a 30-metre section of washed-out track near the highway. Winds at 83 km/h uprooted 300 trees into the Cypress River which empties into Nipigon Bay.
