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: tonight until Saturday evening.
Remarks: Significant runoff is expected to occur as heavy rain combines with mild temperatures, leading to considerable snowmelt. The heaviest rain is expected to begin overnight tonight, and persist into tomorrow afternoon for eastern portions of the province.
A cold front will then sweep across the province on Saturday, with rain changing to snow by the evening, and quickly dropping temperatures to below zero. A period of ice pellets and freezing rain is likely as this transition occurs. 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.
