A frost advisory has been issued across southern Ontario as overnight temperatures are expected to dip below freezing, posing a risk to tender plants and crops. The advisory, announced by Environment Canada, covers a wide swath of the region, including the Greater Toronto Area, and is in effect from late evening through early morning.
Weather Forecast Details
Meteorologist Julie Atchison provided the latest forecast, indicating that clear skies and light winds will allow temperatures to drop near or below the freezing mark. "We're looking at a cold night ahead," Atchison said. "Temperatures could fall to between -1 and -3 degrees Celsius in some areas, which is unusual for this time of year." The frost advisory is expected to remain in place until temperatures rise above freezing in the morning.
Impact on Agriculture and Gardening
Farmers and gardeners are advised to take protective measures, such as covering sensitive plants or bringing potted plants indoors. The frost could damage early-season crops, including fruits and vegetables that have already been planted. "This is a critical time for many growers," said a local agricultural expert. "A late frost can set back production significantly." Residents with home gardens are urged to monitor the situation closely.
Safety Precautions
In addition to plant protection, residents should ensure that outdoor pets have adequate shelter and that exposed pipes are insulated to prevent freezing. The advisory also warns drivers of potential frost on windshields and roads, urging caution during early morning commutes. "Even a thin layer of frost can make surfaces slippery," Atchison added.
This frost advisory follows a series of unseasonably cool nights across the province. While spring officially arrived weeks ago, the lingering cold air mass has kept temperatures below seasonal norms. Environment Canada expects conditions to moderate by midweek, with a warming trend moving in from the west.
For the latest updates, residents are encouraged to check local weather reports and heed any additional warnings. The frost advisory is a reminder that despite the calendar, winter-like conditions can still occur in May.
