A rainfall warning has been issued for much of the province, including the Halifax area, as a storm approaches the Maritimes.
Rain is expected to begin overnight and become heavy around sunrise Tuesday, continuing for much of the day, into the night.
"Heavy downpours can cause flash floods and water pooling on roads," said the weather advisory. "Localized flooding in low-lying areas is possible."
As of 4 p.m. Monday, Environment Canada says Halifax could see up to 65 mm of rain, and as cold, westerly winds move into the region late Tuesday, snow could be mixed in before Wednesday's sunrise.
Forecasters say driving conditions could become icy overnight from Tuesday into Wednesday as cold air and flurries push eastward across the province.
