September delivered seven named storms, headlined by Hurricane Fiona and Hurricane Ian. But 2022′s overall activity ended up somewhat below average, largely because of the season’s defining storm. It only takes one storm to change a season’s outlook. Fiona reached Category 4 on Sept. 22 southwest of Bermuda. The storm battered coastal towns, sweeping away homes and peeling off roofs. A pressure reading on the coast of 933 millibars marked the lowest pressure on record for any storm to strike Canada’s shores.
