Be prepared for a chilly start to your long weekend.
A frost advisory is in effect for the Haliburton, Minden, Southern Haliburton County, Oxtongue Lake, Fort Irwin, and Northern Haliburton County areas.
Temperatures are expected to fall as low as zero tonight and warm up with the sun tomorrow.
Environment Canada suggests that it is a good idea to cover crops and plants because the frost can potentially damage them.
