UPDATE: Environment Canada has ended a special weather statement that had been in effect for the eastern half of the Halifax Regional Municipality.
According to the forecast for that area, as of 4 p.m. Thursday, rain is still coming Friday, but totals should be lower than what was originally expected.
Rain should start falling Thursday evening, with around 10 mm expected tonight in the metro Halifax area, and 10 to 20 mm in HRM east of Porters Lake.
There's also a risk of a thundershower overnight.
Another 5 to 10 mm is expected Friday in metro, and 15 to 25 mm along the Eastern Shore.
A special weather statement has been issued for the eastern half of the Halifax Regional Municipality.
As of 4 p.m. Wednesday, Environment Canada says to expect "significant rainfall" Friday.
For areas east of Porters Lake, between 40 and 65 mm could fall, and totals could be even higher in some spots.
"Heavy downpours can cause flash floods and water pooling on roads," the statement said. "Localized flooding in low-lying areas is possible. Stay clear of fast running rivers and streams."
Rain is expected to start falling Thursday, and could linger into Saturday.
"Rainfall warnings are likely to be issued as the areas receiving the heaviest rainfall amounts become more certain," Environment Canada added.
