Heavy rain, power outages and storm surge predicted during powerful storm
Hurricane Lee is still expected to make landfall in the region on Saturday, however the Maritimes will see wind and rain beginning Friday night.
With the trees in full leaf, power outages are very likely, with widespread wind gusts of 60 to 90 kilometres per hour expected across the Maritimes. The long duration of this storm will increase the chances of outages Saturday and Saturday night.
Areas of southwestern Nova Scotia and New Brunswick are likely to experience the strongest winds with the possibility of sustained winds of 60 kilometres per hour and gusts of 90 to 120 kilometres per hour or higher, especially in exposed coastal areas.

Areas of southwestern Nova Scotia and New Brunswick are likely to experience the strongest winds with the possibility of sustained winds of 60 kilometres per hour and gusts of 90 to 120 kilometres per hour or higher, especially in exposed coastal areas.
Rainfall amounts will be highest along the northwest of the hurricane's track. Totals of 50 to 100 millimetres or more are possible in southwestern Nova Scotia and much of New Brunswick, most of which is set to fall on Saturday and Saturday night.
Further east, totals won't be as high, but heavy downpours are still likely.
The historically wet summer, heavy rain on Thursday and high water tables in the Maritimes will increase the risk of flooding as more rain hits already saturated ground.
Lee is a large storm, so pounding surf is a slam dunk for Saturday, especially for south-facing coastlines. The Atlantic coastline of Nova Scotia is the area most likely to be impacted and the Canadian Hurricane Centre (CHC) is warning of four- to six-metre waves breaking along the coast.
Storm surge is also a concern.
While the Bay of Fundy will need to be watched closely, the CHC has flagged the area of the Atlantic coastline from Shelburne County up to the coast to Queens County and eastern Halifax County as the region most likely to see coastal flooding.
During high tide times, the storm surge combined with waves may push water levels up to one and half metres above the usual high tide.
So when does the storm arrive and when does it leave? Here's a breakdown of what to expect.
Friday — Last-minute preparation
Friday will be a quiet day across the region. Winds will be light and it will be a great day for last-minute preparations.
Friday night — Rain and wind arrive
The first rain bands and gusts of wind are set to arrive through Friday evening & the overnight.
Saturday morning — Winds ramp up
As Lee moves closer to the region, the winds will increase in speed throughout the morning and we'll see bands of rain, at times heavy, tracking through the region.
Saturday afternoon and evening — Lee makes landfall
Lee will likely make landfall in the region in the late afternoon or early evening as the periods of rain and gusty winds continue.
Saturday night — Winds remain gusty
This will be a long storm, so expect the winds to continue to gust through Saturday night as Lee tracks through the region.
Sunday — Lee slowly departs
Some lingering bands of rain and gusty winds are likely to continue into Sunday morning.
As Lee moves into the Gulf of St. Lawrence on Sunday afternoon, we'll likely see some sunshine breaking in across Maritimes.
