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. Temperatures are expected to dip to near- or below-freezing overnight into Friday morning.
Key facts:
- A yellow-level frost advisory was issued for Toronto and several parts of the GTA.
- The advisory applies to a wide stretch of southern Ontario including multiple municipalities.
- Environment Canada indicates a moderate impact level with high confidence in the forecast.
- Thursday’s high is expected to reach only 11°C, with scattered showers.
- Friday’s high will be near 10°C, with a low around 1°C and potential for flurries.
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. Patchy frost is likely to form under clearing skies and cold overnight air.
Frost is typically experienced in the GTA during the last week of April and first week of May. The region is heading into a chilly start to May with daytime highs struggling to reach the low teens. Jessie Uppal from Environment Canada noted, “Typically, we still experience frost through the last week of April and first week of May.”
