A powerful storm Tuesday and Wednesday is expected to bring significant freezing rain, snow and ice pellets to much of New Brunswick.

Forecasters say snow and sleet will begin Tuesday morning and then mix with or change to freezing rain later in the day. Wednesday's wintry mix will be mostly freezing rain and sleet, mixing with snow in northern parts of the province.

Snow and sleet accumulation of 10 to 15 centimetres is likely in most areas, but freezing rain will compound the situation.

The storm could make many roads treacherous and impassable, forecasters say. The weight of the snow and ice on tree limbs and power lines could lead to power outages.

Winds are expected to be from the northeast at 5 to 15 mph with gusts up to 25 mph overnight. Temperatures will climb to near the freezing mark.
