Alerts: Mahone Bay, NS

An intense low pressure system will bring rain, snow, freezing rain and strong winds to Nova Scotia tonight. A rain/snow boundary near the Nova Scotia/New Brunswick border will move southeastward later this evening to lie along the Annapolis Valley to Colchester County region and continue to move southeastward overnight. Heavy snow can be expected north of this boundary with heavy rain to its south. A mix of snow and rain is expected along the boundary combined with an extended period of freezing rain which could lead to significant icing. The bulk of precipitation should end over Western Nova Scotia overnight and by Sunday morning over eastern mainland Nova Scotia. Over Cape Breton, periods of snow will continue through the day Sunday. Strong southerly winds will develop ahead of the low pressure system overnight over Cape Breton. Winds of 60 km/h with gusts to 100 km/h are forecast. Over Northern Inverness county, Les Suetes winds will gust up to 110 km/h overnight. The storm will also produce a storm surge. This in combination with a run of high astronomical tides will produce higher than normal water levels at the high tides tonight and Sunday. This will be particularly so for the Atlantic coast of Eastern Nova Scotia and Cape Breton at the high tide near midnight tonight when rough and pounding surf is also expected. Additionally the Northumberland strait will experience some ice rafting at the high tide near noon on Sunday as strong winds drive the ice onshore along north facing coastlines. The ice in the Southern Gulf of St. Lawrence should limit the development of rough and pounding surf.
