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.

The strongest winds are currently expected in the southwest Maritimes where gusts may exceed 90 km/h. Widespread gusts 60-90 km/h elsewhere.

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.

The heaviest rainfall is currently expected to fall in southwestern Nova Scotia and in New Brunswick, which is along and northwest of the track.

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.

There will be risk of coastal flooding along the Atlantic coast during high tide times on Saturday.

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.

Tropical moisture surges in Nova Scotia ahead of Hurricane Lee

Meteorologist Ryan Snoddon says Lee could make landfall as a post-tropical storm with tropical storm-force winds at about 110 km per hour, which he notes is just a little bit less than the force of a Category 1 storm.

Friday — Last-minute preparation

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.
