"...the 14th Century economic bubble burst following the Soap Blizzard of 1378... Harry, you startled me! But I won't deduct extra house points, just the usual 5 for interrupting."
—Harry Potter interrupts Cuthbert Binns' lecture on this blizzard[src]

The Soap Blizzard of 1378 was, presumably, a blizzard of soap that occurred sometime in 1378. This blizzard was followed by a burst of the wizarding economic bubble. Cuthbert Binns was giving a lecture on these events to a class during the 1991-1992 school year when he was accidentally interrupted by Harry Potter.
