Snowfall rates as high as 5 cm per hour are possible along the eastern shores of Nova Scotia through Monday afternoon, leading to fast accumulations.
High winds are likely for the duration of the storm, with gusts up to 90 km/h for exposed coastal areas. The combination of heavy snow and high winds will lead to whiteouts and a potential period of blizzard conditions for portions of Nova Scotia and Prince Edward Island.
Dangerous travel is expected for the evening commute. Prepare for school and business closures on Monday and Tuesday. Flight cancellations are almost certain. Power outages are possible. High winds may also lead to coastal flooding in some locations.
