A late-April cold snap has led to a yellow-level frost advisory across Toronto and the GTA, prompting residents to take precautions for their plants. Environment Canada issued the advisory early Thursday morning, warning of temperatures dipping near or below freezing overnight into Friday.
Key facts:
- A yellow-level frost advisory was issued for Toronto and several parts of the GTA.
- Temperatures are expected to dip to near- or below-freezing overnight into Friday morning.
- The advisory applies to a wide stretch of southern Ontario including multiple municipalities.
- Patchy frost is likely to form under clearing skies and cold overnight air.
- Thursday’s high is expected to reach only 11°C, with scattered showers.
Residents are urged to cover vulnerable plants or bring potted ones indoors—especially in frost-prone or low-lying areas where temperatures can fall more quickly. Jessie Uppal from Environment Canada noted that frost is typically experienced in this region during the last week of April and first week of May.
The forecast for Friday looks similarly chilly, with highs around 10°C and lows near 1°C, along with potential flurries. This cold snap serves as a reminder that spring weather can be unpredictable, even in late April.
