Yellow Advisory - Frost
3:41 p.m. CST Saturday 12 September 2026

Impact Level: Moderate

Forecast Confidence: High


Frost is expected tonight.

A surface ridge of high pressure will move into southern Saskatchewan tonight, clearing skies and cooling temperatures to freezing or just below freezing.

Frost may be patchy in some areas as patchy fog is expected to form, which may keep temperatures above freezing.

Damage to plants, trees, and crops is possible.

Take preventative measures to protect cold-sensitive plants, trees, and crops. Cover up plants, especially those in frost-prone areas.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to SKstorm@ec.gc.ca, call 1-800-239-0484 or post reports on social media using #SKStorm.
