A winter storm watch has been issued as a Colorado low barrels towards the region.

Environment Canada says between 25 and 40 cm of snow will fall across the region starting Wednesday morning into Friday morning.

The weather agency warns of strong wind gusts up to 70 km/h, leading to widespread blowing snow and blizzard conditions due to heavy snow and blowing snow.

There is uncertainty in the exact track of this low-pressure system and total snowfall amounts as a result. This watch will be upgraded to a warning in the coming days as exact details concerning this system become more certain.

Avoid travel if possible. Travel is expected to be hazardous due to reduced visibility in some locations. Poor weather conditions may contribute to transportation delays. If you must travel, keep others informed of your schedule and destination and carry an emergency kit and mobile phone.
