Prepared by: Peter Bowyer
Six tropical cyclones entered the Canadian Hurricane Centre (CHC) Response Zone (RZ) during the 2001 season.

This is the third consecutive year during which 6 tropical cyclones have done so. The past 7 years have seen an average of 5.7 storms. Notably, within one 30-day span, four tropical cyclones passed through the Southwestern Grand Banks marine area.
For the second consecutive year, a tropical cyclone made landfall in Atlantic Canada. Tropical Storm Karen came ashore over southwestern Nova Scotia during the morning of October 15 before weakening over the Gulf of St. Lawrence that afternoon.
The CHC issued 110 bulletins during 2001.
Note: The CHC has discontinued the FXCN05 CWHX bulletin. All information regarding tropical cyclones is now included in a redesigned WTCN31/71 CWHX.

|Number of Storms|
Dean (August 22–28)
After reforming just north of Bermuda, Tropical Storm Dean entered the CHC RZ on August 27 and continued northeastwards across the Grand Banks marine areas southeast of Newfoundland. Maximum wind speeds were near 102 km/h and significant wave heights were near 6 m. Heavy rainfalls were reported to the left of the track. Bonavista, on the east coast of Newfoundland, reported 107 mm from the evening of August 27 until midday on August 28. Numerous marine warnings had been issued by both the Maritimes Weather Centre and the Newfoundland Weather Centre.
Erin (September 1–15)
After passing about 200 km east of Bermuda, Hurricane Erin entered the CHC RZ on September 14, then tracked northeastwards and skirted the Avalon Peninsula of Newfoundland. Maximum wind speeds were estimated at 130 km/h with significant wave heights of 9.3 m. The maximum recorded wave height (Nickerson Bank buoy, 44251) was 14.4 m. Heavy rainfalls were also reported over portions of Newfoundland. Sagona Island, along the south coast, recorded 131 mm. Numerous marine and public warnings had been issued by both the Maritimes Weather Centre and the Newfoundland Weather Centre.
Gabrielle (September 11–19)
Gabrielle was the second storm to hit eastern Newfoundland in less than a week. Although a post-tropical storm as it passed just southeast of the Avalon Peninsula, significant rainfalls and strong winds resulted. Even though Gabrielle passed farther offshore than Erin, it gave worse conditions. Record rainfalls were recorded, with between 100 and 175 mm over the Avalon Peninsula. Much of this fell within a 6-hour period, and one station in St. John’s West broke its 6-hour rainfall record by 10 mm. The 175 mm were recorded at Memorial University of Newfoundland. Widespread wind gusts in excess of 100 km/h were reported along the south and east coasts, with a maximum gust of 130 km/h recorded at Cape Race. Significant wave heights reached near 11 m. There were major flooding problems and road washouts in the capital of St. John’s. Having declared it as “the worst storm in 100 years,” the mayor of St. John’s activated the city’s Emergency Response Program. The Newfoundland Weather Centre issued numerous warnings in advance of Gabrielle, while the CHC dealt with many media interviews.
Humberto (September 21–27)
Hurricane Humberto entered the CHC RZ on the September 26 and turned eastwards shortly thereafter. Consequently, Humberto had minimal effects on Canadian land. Over seas, however, maximum winds were estimated at 167 km/h--a solid Category 2 hurricane on the Saffir‑Simpson Hurricane Scale. Due to the direction in which Humberto traveled, highest seas were outside the Canadian marine district. The Maritimes Weather Centre and the Newfoundland Weather Centre issued mainly marine warnings for southeastern waters. The final bulletin was issued on the morning of September 27 before Humberto headed out over the Atlantic.
Karen (October 12–15)
Karen was the second tropical cyclone to make landfall in Canada in 2 years. After developing from a non-tropical low east of Bermuda, Karen tracked northward and made landfall near Liverpool, Nova Scotia, as a tropical storm. Maximum wind speeds at landfall were near 83 km/h. Maximum gusts of 104 km/h were recorded at McNabs Island near Halifax, as well as at Cape George, Antigonish County, Nova Scotia. Maximum rainfall amounts were not significant; however, the 46.0 mm that were reported from Yarmouth fell in a matter of a few hours.
Noel (November 4–6)
Noel was a relatively short-lived storm that weakened while crossing the extreme southeastern Grand Banks near Newfoundland. No significant effects were felt over land. The maximum wind speed, while in the CHC Area of Responsibility, was estimated at 93 km/h. As a result, the Newfoundland Weather Centre issued marine wind warnings.
