"The Maritimes will see the arrival of Andrea's rain late this evening with the heaviest rain moving in early tomorrow [Saturday] morning accompanied by strong winds," CBC meteorologist Jay Scotland on Friday morning.
"At the moment, southern New Brunswick and Nova Scotia look to see as much as 30 to over 60 mm of rain with the highest amounts falling from New Brunswick's Fundy coast across the bay to both central and southern Nova Scotia."
The U.S. National Hurricane Center said in a statement released Friday evening that Andrea had become a post-tropical storm. The storm was located about 90 kilometres east-northeast of Raleigh, N.C., the hurricane centre said, and was moving northeast at about 44 km/h.
"This general motion with an increase in forward speed is expected through Saturday," the statement said.
On the current forecast track, the storm is expected to move northeastward through Saturday and "across Atlantic Canada late Saturday through Sunday," the U.S. forecasters said.

"Even though Andrea will no longer be a tropical storm as it rolls through the Maritimes, its remnants will still be packing strong winds as it crosses the region tomorrow with wind gusts from 70 to 100 kilometres per hour possible to go along with heavy rain," Scotland said earlier Friday.
The rain and strong winds are expected to move to southwest Newfoundland by Saturday evening.
Gale warnings have been issued for all marine waters south of Nova Scotia for Saturday, where wave heights of four to five metres will develop.
Andrea has hammered Florida with rain, heavy winds and tornadoes as it moved toward the coast of Georgia and the Carolinas.
Officials in South Carolina said there were no reports of injuries or significant damage.
