A Durham frost advisory is in effect for Pickering, Oshawa and southern Durham Region as temperatures are expected to approach the freezing mark overnight.
Environment Canada issued the yellow advisory at 10:45 a.m. EDT on Friday, October 9. The alert covers Friday night into early Saturday morning.
Patchy frost is expected overnight
The federal forecast for Oshawa calls for a low of 2 C Friday night with patchy frost. Skies are expected to clear before becoming partly cloudy after midnight.
Environment Canada says frost or near-freezing temperatures can damage sensitive plants, trees and crops. Residents are advised to cover cold-sensitive plants, especially in locations that are prone to frost.
The alert’s impact level is listed as moderate and forecast confidence as high. Environment Canada issues frost advisories when frost or freezing temperatures are expected during the growing season.
Saturday is expected to warm quickly
The Oshawa forecast calls for mainly sunny conditions Saturday, with a high of 18 C and a southeast wind developing in the afternoon. The cold overnight period is therefore expected to be brief, but exposed vegetation can still be affected before temperatures rise.
The Durham frost advisory applies specifically to Pickering, Oshawa and southern Durham Region. Conditions can differ farther north, so residents should check the current alert for their location.
Weather alerts can change or end as new observations and forecasts become available. Gardeners, growers and anyone protecting outdoor plants should confirm the latest Environment Canada notice Friday evening.
