Claudette, a tropical storm, may affect Atlantic Canada on Tuesday, bringing rain to some areas.

The storm was considered a depression over the weekend but it regained strength overnight Sunday. It claimed 12 lives Saturday as it passed through Alabama and brought flooding to a number of southern U.S. states.

CBC meteorologist Tina Simpkin said the storm was located over South Carolina Monday morning with sustained winds of 65 km/h moving northeast at 41 km/h, a track that would take it south of Nova Scotia Tuesday morning.

She said there could be 5-15 millimetres of rain late Tuesday afternoon with enhanced rainfall from Guysborough County to Cape Breton Tuesday night, with 10-15 millimetres in those areas.

By Tuesday evening, Claudette would be post-tropical and continue to lose strength as it headed northeastward.

According to the Canadian Hurricane Centre on Sunday, the system had winds of up to 137 km/h when it passed over northern Florida, but forecasters said it was expected to stay south of Nova Scotia.

The hurricane centre said it was also possible Claudette could weaken into a low-pressure trough by Tuesday.

It advised that winds up to gale force could occur over southern Canadian waters.
