A snow squall watch is in effect for the Northumberland and Quinte regions.
Environment Canada has issued watches for the eastern and western portions of the county, as well as the Quinte West and Belleville areas.
Officials initially predicted possible snow squalls starting Tuesday night (Dec. 3) through to Wednesday, Dec. 4. In an updated alert Tuesday afternoon, officials are now saying potential squalls are anticipated starting Wednesday morning and through the night.
“Lake effect snow squalls over Lake Ontario could move inland early Wednesday morning, affecting Hwy. 401 during the morning commute. Snow squalls may move in and out of the area Wednesday before moving back south over the lake Wednesday night,” reads the alert.
Potential hazards noted include locally heavy snowfall with accumulations near 20 centimetres – and peak snowfall rates of two-to-five cm per hour are possible. Poor visibility in times of heavy snow is anticipated.
Snow squalls cause weather conditions to vary considerably – changes from clear skies to heavy snow within just a few kilometres are common, explained Environment Canada.
Officials suggest people consider postponing non-essential travel until conditions improve where possible.
For people who have to travel, keep others informed of your schedules and destinations and carry an emergency kit and cellphone.
Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.
