Today's Weather Trivia

25 October

1840: A gale, among the most severe in 20 years, assaulted Saint John, NB. Waves ran to a great height, sending spray a long way and at one time immersing the Beacon Lighthouse. Wind-wave action damaged several smaller vessels in the harbour and forced many large vessels from their moorings. Two men on a raft drowned. The gale also razed 2 buildings, carrying off parts of their leaden roofs.
