Green thumbs across central Alberta are urged to take precautions as Environment Canada issues a frost advisory for tonight. Typically, gardeners in the region can safely plant after the May long weekend, but a cold air mass is expected to bring temperatures near or below freezing overnight.
The advisory covers a wide area from Calgary to north of Edmonton, including Athabasca, Swan Hills, and extending eastward to Vegreville and Castor. According to Environment Canada, clear skies and cold air will contribute to patchy frost, potentially damaging sensitive crops.
Phil Darlington, a weather specialist at Global Edmonton, forecasts temperatures dipping to 2 to 4 degrees Celsius in Edmonton. Outlying areas could experience even colder conditions, dropping to or below zero.
Gardeners are advised to protect frost-sensitive plants by covering them or moving them indoors. However, even with precautions, some crops like tomatoes may still be at risk. Darlington suggests harvesting beans, peas, and mature corn immediately if a hard frost is expected, while apples and root vegetables like carrots and potatoes can withstand light frosts.
The advisory serves as a reminder that despite the season, unexpected weather can threaten gardens and crops, prompting proactive measures to minimize potential losses.
