The well-mixed Atlantic waters off the Bay of Fundy are among the foggiest areas of the world, although not as notoriously foggy as the Grand Banks of Newfoundland. The season with the greatest contrast in temperature between sea surface and overriding air produces the greatest fog.

The Saint John River has a history of flooding dating back to the arrival of the first European settlers. Within this century there have been at least six floods which have caused damage in excess of one million dollars. A flood such as this is likely to occur only once in 70 years. Conditions in late April 1973 were ripe for serious flooding.
