New winter storm expected to dump 30 cm of snow in north, 40 mm of rain in south
Meanwhile up to 40 mm of rain is expected for southern parts of the province
A messy combination of snow, rain and ice pellets is expected to hit the province this week, according to Environment Canada.
In a snowfall warning, the weather agency said northern New Brunswick can expect between 15 and 30 centimetres as low pressure system moves in from the Great Lakes.

"Snow associated with this low will begin tonight then likely change over to ice pellets Tuesday afternoon then to freezing rain and rain Tuesday night," Environment Canada said in statement, early Monday morning.
There is a possibility of an extended period of freezing rain Tuesday night, the weather agency said.
"Rapidly accumulating snow will make travel difficult. Visibility may be suddenly reduced at times in heavy snow."

A special weather statement is also in effect for southern parts of the province, where 20 to 40 millimetres of rain is expected.
The southern parts of the province can also expect around 10 centimetres of snow.
Environment Canada said precipitation will start as snow over western New Brunswick on Monday night, then spread to the eastern part of the province by Tuesday morning.
Snow will change to ice pellets then to freezing rain before changing over to rain for southern New Brunswick on Tuesday and Tuesday night for northeastern New Brunswick. Freezing rain is expected in northwestern New Brunswick.
Some areas could experience an extended period of freezing rain during the changeover but precipitation is expected to end by Wednesday morning.
"Due to the potential rainfall amounts expected with this storm a significant amount of melting of the existing snow on the ground will give enhanced runoff," Environment Canada said.
"This will potentially lead to some flooding in vulnerable areas."
