Overview
- A Pacific storm will affect Vancouver Island and the South Coast on Halloween with very strong winds, including gusts near 100 km/h in exposed areas and up to 80 km/h over the Strait of Georgia, and forecasters urge residents to secure outdoor decorations.
- Environment and Climate Change Canada issued rainfall warnings for the Sunshine Coast, Howe Sound, and parts of Metro Vancouver, with 15–25 mm expected in southern sections of the Lower Mainland and near 50 mm closer to the North Shore mountains.
- Rain on the South Coast is forecast to taper somewhat early Friday evening before returning overnight, while West Vancouver Island (Tofino–Ucluelet) is expected to stay wet through trick-or-treating and East Vancouver Island and Victoria remain breezy with lighter showers.
- A separate system will bring wind and heavy rain to the western Maritimes beginning Friday morning, with forecasters expecting a lull during prime trick-or-treat hours in western Nova Scotia and southern New Brunswick as heavier rain focuses on Prince Edward Island and eastern Nova Scotia.
- Hurricane Melissa is forecast to pass just east of Newfoundland overnight Friday, with the Canadian Hurricane Centre warning of large waves and a coastal flooding risk on the Avalon Peninsula.
