1967: 19” of rain in 24 hours in Ucluelet, BC

Ucluelet, British Columbia is located on the west coast of Canada on Vancouver Island. It has an oceanic climate like that of Ireland, with mild, rainy winters and cool summers owing to its coastal location. As such, precipitation is high, averaging around 132 inches per year, with most of it concentrated in the winter months. Even so, precipitation is significant in all months with no month averaging below 3 in of precipitation. Although it has an average snowfall of 12.8 inches, the median is 0, meaning more than 50% of years do not experience a single snowfall; this makes this climate unique in Canada. The region is prone to massive storms that sweep in off the Pacific Ocean, mainly in the winter. One reason it does not get much snow is because of the influence of the warming of the Pacific waters on the atmosphere. In October 1967 an early season winter-type storms blasted southward from the Gulf of Alaska and brought the region 19.61” of rain in 24 hours on October 6. That total of close to 20” in a day is the greatest 24 hours rainfall total ever in Canada.
