Today's Weather Trivia

2 September

1876: At noon, the weather head office in Toronto, ON, ordered Maritime harbours and lighthouses to hoist storm drums. There were no signs of a storm, and quiet jokes were made about the forecast. By evening, the wind, accompanied by showers, grew into a gale, which by daylight was a fierce storm. Likely, this was the fledgling national weather service's first storm warning.
