After snow fell across much of Eastern Nova Scotia today that came from a passing storm, the next system is hot on its heels. This next storm will bring rainfall to the province along with Prince Edward Island and Southern New Brunswick beginning late Friday afternoon and continuing until Saturday evening.
The hardest hit areas already have a substantial base layer of snow from the past few weeks, particularly the Halifax area and eastward to include the Northumberland Shore and Cape Breton Island, and these areas can now expect 30-50mm of rain. The snowpack and frozen ground means that rain will not be readily absorbed so localized flooding is a major concern. These areas will also see significant melting and runoff alongside the rainfall with temperatures staying above freezing throughout the event, adding to flooding and drainage issues. Make sure to keep all storm drains cleared so that the water has somewhere to drain to.
As the rain dissipates starting Saturday afternoon from west to east, the temperatures will plummet below freezing and into negative double digits in many areas overnight. As a result, we will see very icy conditions as the water from the rain and melted snow freezes.
