HALIFAX – Residents of the Maritimes are bracing for another wintry blast.

Environment Canada is warning the entire province of New Brunswick to prepare for extremely cold temperatures tonight – followed by snow on Wednesday.

The forecast is calling for wind-chill values to drop to between -35 C and -40 C.

The extreme-cold warning has been extended to Prince Edward Island, where strong northwesterly winds will make the temperature feel like -35 C.

In Nova Scotia, extreme-cold warnings are in effect for Cape Breton, the province’s eastern shore and northern parts of the province.

As well, a special weather statement is warning that a low-pressure system will bring snow changing to rain during the day on Wednesday for much of Nova Scotia.

Flooded basements and leaky roofs have been reported across the Halifax region today after heavy rain swept over the city on the weekend.

A large buildup of snow and ice on city streets has left many catch-basins blocked, leading to flooding in low areas.

As well, the accumulated snow on roofs is being blamed for creating ice dams and resulting leaks.

At one point, city officials say they were receiving up to 25 reports of flooding every hour on Sunday.

Meanwhile, the Halifax Regional School Board has closed several schools because of water damage.
