Thousands of New Brunswickers, mainly in southern communities, are waking up without electricity on Wednesday morning.

NB Power reported that roughly 6,200 customers were without power 8:20 a.m. with the largest share of outages in the Charlotte Southwest region.

Meghan Gerrish, a NB Power spokesperson, said several hundred customers have already had their power reconnected on Wednesday morning.

Gerrish said the main cause of the outages seems to be trees falling on lines.

Officials are still assessing the damage but the utility has ordered crews from other parts of the province to travel to the affected areas to help restore the power.

Campobello Island Consolidated School has been closed and students at St. George Elementary School and Back Bay Elementary School will be returned home.

The outages come as the province experiences another swing in temperatures.

The day after every school in the province was closed on Tuesday because of freezing rain, the latest weather system has brought a taste of spring to the Maritimes.

Peter Coade, a CBC meteorologist, said for a few hours on Tuesday some communities in Nova Scotia were the warmest in Canada.

A cold front will now bring a cooler, more seasonable air mass, into the region, which will clear away the cloud but temperatures will fall slowly.

"This feature holds the promise of mostly sunny days and mainly clear nights for the the next couple days at least," Coade said.

But Coade said it looks like another weekend disturbance will move in from the west with showers and flurries for Saturday.
