Even more rain than initially predicted is in the forecast for southwest Nova Scotia and rainfall warnings have now been issued for most of the province.
According to the updated rainfall warning for the region from Environment Canada, amounts of 30 to 60 millimetres are expected today and continue into Sunday morning.
An intense low pressure system currently over the Great Lakes is expected to track across Quebec tonight and Sunday. The system is forecast to push a warm front over the Maritimes. Rain associated with this system is currently over western Nova Scotia and will spread eastward this afternoon and continue into Sunday. Total rainfall amounts of 30 to 60 mm are expected with highest amounts over western parts of the province and along the Atlantic coast.
Strong southerly winds and very mild temperatures will combine with the rainfall to cause significant melting of the existing snowpack thereby increasing the risk of flooding.
