Frost may damage some crops in frost-prone areas.
An unseasonably cold arctic air mass has become entrenched over Southern Ontario.
Temperatures tonight are expected to plunge to near or a couple degrees below the zero degree mark in most areas under partly cloudy to mainly clear skies and diminishing winds. Hence widespread frost is likely across most of of the region overnight into Monday morning.
Tender plants should be protected or brought indoors by this evening.
Temperatures will slowly recover above the freezing mark Monday morning.
Take preventative measures to protect frost-sensitive plants and trees.
Frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to email@example.com or tweet reports using #ONStorm.
