A chilly reminder that the growing season in Newfoundland comes with a few caveats. Environment Canada has issued a frost advisory for much of the island tonight, with temperatures expected to dip close to or below freezing in the colder, low-lying areas. If you’ve got a garden on the go or tender plants outside, tonight’s the night to give them some cover. Here’s the rundown:

A Frost Advisory is in effect for much of eastern, central and northern Newfoundland tonight into early Monday morning.

Areas under the advisory:

• Avalon Peninsula North

• St. John’s and vicinity

• Grand Falls-Windsor and vicinity

• Bay of Exploits

• Bonavista North

• Bonavista Peninsula

• Clarenville and vicinity

• Gander and vicinity

• Green Bay – White Bay

• Terra Nova

• Northern Peninsula East

• Parson’s Pond – Hawke’s Bay

• Port Saunders and the Straits

The details:

Conditions are favourable for patchy frost to develop tonight, with partly clear skies and light winds teaming up with cool air. Minimum temperatures are expected to dip to between -1 and +4 °C, coldest in low-lying and frost-prone spots. The risk runs through early Monday morning.

What to do:

Take steps to protect cold-sensitive plants, trees, and crops. Cover up anything vulnerable, especially in low-lying areas where the cold settles first.
