On Thursday afternoon, Gabrielle was located about 365 kilometres northeast of Bermuda with maximum sustained winds of 65 km/h.
The storm has begun to accelerate northward and is expected to merge with a cloud front near New England, according to the Canadian Hurricane Centre. The system is expected to bring heavy rain into parts of Atlantic Canada on Friday and into the weekend.
Rainfall warnings are expected for parts of central and northeastern Nova Scotia, as well as Queens and Kings County P.E.I.
Gabrielle was downgraded to a depression but regained tropical storm status earlier on Thursday.
"Gabrielle, while still a tropical storm Thursday afternoon, is likely to become post-tropical as it approaches Nova Scotia Friday. Now whether the storm is tropical or post-tropical on Friday makes little difference to the forecast here in Nova Scotia. Moisture brought up from near Bermuda with Gabrielle will wrap into a cold front approaching from New Brunswick. The result on Friday will be rain, heavy at times, for large parts of Nova Scotia,” said CBC meteorologist Kalin Mitchell.
“Rainfall amounts for some parts of the province are likely to be in the range of 50 to 100 millimetres. With rain that heavy we will have to watch out for things such as localized flooding and hydroplaning conditions on the roads. Winds will be gusty on Friday but unlikely to exceed 80 km/h so it is the rain that is the biggest concern at this time."
The Canadian Hurricane Centre does not expect much of a change in the storm’s intensity, according to the centre’s latest weather bulletin.
In Bermuda, Gabrielle caused several power outages overnight, but no major damage was reported on the British territory.
Meanwhile, Hurricane Humberto — this season’s first hurricane — is maintaining its strength far out over the Atlantic Ocean heading northward.
The category 1 hurricane, centred 705 kilometres over the Cape Verde Islands, has maximum sustained winds near 140 km/h, but the U.S. National Hurricane Centre is expecting it to weaken over the coming days.
