Environment Canada said a stream of tropical moisture will bring showers, at times heavy, to parts of the Newfoundland's southern coast, as well as to the northern and western areas of the province.
Between 15 and 45 millimetres of rainfall is expected in these regions by Sunday morning.
Gabrielle was the first named storm of the 2013 hurricane season to make landfall in Canada.
The tropical storm was downgraded to a tropical depression on Friday afternoon, bringing as much as 70 millimetres of rain to parts of Nova Scotia, New Brunswick and P.E.I.
Rain is expected to persist in the Maritimes throughout Saturday as the remnants of Gabrielle pass by.
Though there were some fears that flash flooding could cause damage, no excessive flooding was reported in any of the Maritime provinces.
