Rain is also expected tomorrow along the Atlantic coast, especially in the southwest, where snowfall amounts will be much lower than inland Nova Scotia.

Environment Canada says that by Friday morning, mainland Nova Scotia is expected to see between 15 - 25 centimetres of snow accumulated. 

The warning says heavy rain is expected in on the southeastern and eastern shore.

'It would be significantly less than in (hurricane Dorian) last year,' said Victor Oulton, president of the Nova Scotia Federation of Agriculture.

Its tropical storm-force winds were extending outward about 100 kilometres to the south of the centre.

Extreme heat can lead to dangerous health risks for people who can't find shelter, or, stay hydrated.

Leaving an unattended animal in a car, in conditions that would cause distress, can result in a $697.50 fine.

It may be the May long weekend, but all of Nova Scotia is under a frost advisory issued by Environment Canada. 

Environment Canada has issued a special weather statement for northern, central and eastern Nova Scotia as well as the southern half of Cape Breton Island. 

According to a special weather statement from Environment Canada, the system is expected to move in Thursday night through to Friday.
