From Environment Canada:
Rain, heavy at times is expected. The frozen ground has a reduced ability to absorb this rainfall.
Locations: most of Nova Scotia, including Cape Breton.
Total rainfall: 25 to 50 mm, with locally higher amounts possible.
Maximum wind gusts: southerly 50 to 70 km/h, potentially higher along the Atlantic coast.
Time span: ending over western Nova Scotia this morning and later this afternoon for eastern mainland Nova Scotia and Cape Breton.
Remarks: Significant runoff is expected to occur as heavy rain combines with mild temperatures, leading to considerable snowmelt.
A cold front will sweep across the province throughout today, with rain changing to snow by the evening and temperatures quickly dropping below zero. A period of ice pellets and freezing rain is likely as this transition occurs, especially over eastern areas of the province. Surfaces such as highways, roads, walkways, and parking lots may become icy and slippery as a result of rapidly dropping temperatures.
Similar storms in the past have caused hazardous driving conditions from water pooling on roadways, and localized flooding, especially in poor drainage areas. Be sure to clear storm drains and gutters of ice and other debris.
Localized flooding in low-lying areas is possible.
Rainfall warnings are issued when significant rainfall is expected.
