Weather system stretching from Gulf States to Atlantic Canada continues risk of thunderstorms

A weather system extending across Atlantic Canada continues to bring periods of showery weather along with a risk of thunderstorms.

A weather system extending from the Gulf States, up the eastern United States seaboard, and across Atlantic Canada continues to bring periods of showery weather along with a risk of thunderstorms.

For Monday afternoon and evening, the chance of thunderstorms is highest in southern New Brunswick and near the Atlantic coastline of Nova Scotia. It is possible that the thunderstorms near the Atlantic coastline of Nova Scotia could hold mostly offshore.

Another round of rain arrives for Nova Scotia late Monday night into Tuesday morning. There is a chance of embedded thunderstorms with that as well. The risk of thunderstorms start around 10 p.m. to midnight near the Atlantic coastline of the mainland. Both eastern Nova Scotia and the southwest of the province with a risk of thunderstorms extending into Tuesday morning.

The weather front is tapping into moisture from the subtropical Atlantic. Downpours producing localized rain totals 50-plus mm are possible with occurring thunderstorms. That increases the chance of hazards such as reduced visibility on roads in the heavier rain, hydroplaning conditions, and localized flooding.

While slow moving, the area of low pressure and associated weather front is expected to clear the Maritimes on Tuesday. A low chance of showers in southeastern New Brunswick and Prince Edward Island could be possible on Tuesday. Showers are forecast to end in Nova Scotia Tuesday afternoon and early evening.
