A powerful January storm brought intense winds and record-breaking snowfall to parts of Newfoundland on Friday into Friday night.
A new all-time daily snowfall record was established at St. John's International Airport.
New record: 76.2 cm (January 17, 2020).
Previous daily record: 68.4 cm (April 5, 1999).
Records began in 1942.
The above total is applicable for the January 17 climatological day, which is a 24 hour period ending at 2:30 A.M. NST on January 18. An additional 2.0 cm was recorded after 2:30 A.M.
The area of low pressure responsible for the snow and wind emerged from the northeastern United States early Thursday and began to rapidly intensify as it moved over the Gulf of Maine. The system deepened into a powerful storm as it tracked southeast of the Avalon Peninsula on Friday, before departing into the North Atlantic early Saturday.
The storm battered the eastern half of the island with heavy
snowfall, extremely high winds and damaging coastal storm surge.
