After heavy snow, N.B. sees temperatures plunge, especially in northwest
Many schools were closed for the day because of overnight snow
Much of New Brunswick slowed down Monday after a heavy overnight snowfall closed schools and created messy roads.
Cleanup was taking place as temperatures headed below -20 in many places.
The Edmundston area is under an extreme cold warning, with a nighttime low of -27 expected, and a windchill of -38.
Extreme cold is also expected from Monday night into Tuesday morning for Campbellton, Grand Falls, Mount Carleton and Restigouche County.
These warnings are issued when very cold temperatures or wind chill could put people at an increased risk of health trouble, such as frostbite and hypothermia.
In other parts of the province, including Bathurst, Fredericton and western New Brunswick, overnight temperatures of -20 or lower were in the forecas.
On Monday morning, drivers were advised not to travel on several highways.
The advisories were later lifted, but some highway routes in province were still listed as snow-covered or partially covered.
