Old Man Winter is making his presence felt in Chatham-Kent today.

A snowfall warning remains in effect with a Texas low bringing heavy snow to the area.

Officials with Environment Canada warn that conditions could change quickly, and have a significant impact on travel.

Some areas could see as much as 15 cm of snow today, tapering off to flurries overnight.

With that in mind, student transportation officials have cancelled all school buses for the Lambton Kent and St Clair Catholic District School Boards in zones one through 8 today, covering all of Chatham-Kent and Lambton County. Buses serving the Providence Catholic School Board are also cancelled.

Most schools remain open today, however high schools with the LKDSB will be closed and students shifting to teacher-led virtual learning.
