Steadily tracking over cooler waters toward the northwest, Nicole lost all of its tropical characteristics and was declared fully extratropical on October 11, 345 miles (555 km) south-southeast of Halifax, Nova Scotia. The Canadian Hurricane Centre continued to issue advisories on what was then called "Post-tropical Storm Nicole", which had now merged with a stronger mid-latitude cyclone. This weather system produced heavy rainfall across the Maritimes near Anticosti Island on October 14.
