Shovelling: Take frequent breaks and avoid overexertion. If you can, shovel more often instead of waiting for the full accumulation.
Weather Trivia
Thunder Bay’s snowstorms often get an extra boost from Lake Superior. When winds push moist air inland, snowfall can ramp up quickly—especially over higher terrain—creating sharp differences in totals across the city.
