Today's Weather Trivia

23 November

1797: When the HMS La Tribune ran aground near Herring Cove, NS, the captain ordered 44 cannons tossed overboard so the ship would float free with the rising tide. Unfortunately, he threw them over the lee side, and as the wind came up to gale force, the ship was battered against the guns. It sank in 20 m of frigid water as the men clung to the rigging. The seas were too high to mount a rescue, and 250 men perished.
