50 mm of rain possible
Rain at times heavy will give up to 50 millimetres on Tuesday.
A developing low pressure system will pass south of the Great Lakes this evening then intensify as it continues northeastward on Tuesday to cross Northern New Brunswick Tuesday evening. As this system approaches the Maritimes on Tuesday it will push a strong warm front into the region which will bring rain at times heavy along with strengthening southeasterly winds and milder temperatures.
Most of Mainland Nova Scotia will see 20 to 30 millimetres of rain except over southwestern sections of the province and along parts of the Atlantic coast where 30 to 50 millimetres are possible. Embedded thundershowers are also possible in these areas later in the day. Southeasterly winds will increase steadily across Mainland Nova Scotia beginning Tuesday morning and are expected to gust to 80 km/h at times during the day.
It is possible wind warnings may be added if this system intensifies slightly more than is currently anticipated.
