Newfoundland Storm Totals
Environment and Climate Change Canada has released storm totals from the heavy rain and strong winds that hit western and southwestern Newfoundland from a low pressure system that stalled off the coast.
The heaviest rain was concentrated over southwestern areas, with amounts drastically lower elsewhere. This system also brought a period of strong southeasterly winds to the island.
The torrential rain contributed to considerable flooding over southwestern Newfoundland, with road washouts and ongoing closures.
The two-day rainfall total of 165.1 mm on November 23-24, 2021 at Port aux Basques broke the previous highest two-day rainfall record of 133.9 mm at the location, set April 28-29, 1982.
The 24-hour rainfall amount of 136.1 mm for the 24 hour period ending at 2:30 P.M. NST on November 24, 2021 at Port aux Basques establishes a new record highest 24-hour amount for a synoptic observation at the location. The record prior to this event was 118.0 mm, set July 17-18, 1979.
