Toronto and the Greater Toronto and Hamilton Area (GTHA) are currently under a special weather statement as a cold front brings showers and a risk of thunderstorms to the region this Saturday.
Rainfall and Flooding Risks
Environment Canada reports that the moving cold front will bring showers throughout Saturday afternoon. Some areas may see rainfall totals between 10 and 20 mm, which creates a risk of flooding in low-lying areas.
The risk is amplified by recent weather patterns. The national weather service states that portions of the region have already received significant rainfall over the last few days, leaving the ground near saturation.
Because the ground has a limited capacity to absorb further moisture, additional rainfall could have significant impacts on the region.
Significant Temperature Drop
The cold front will trigger a sharp decline in temperature overnight as cold northwesterly winds sweep across the region on Sunday. Even as some sunny breaks are expected, highs will likely struggle to reach double digits.
Temperatures are forecast to plunge below zero overnight on Sunday. Scattered showers may as well continue throughout the day.
Outlook for Monday
Conditions are expected to become even colder by Monday. The forecast predicts a mix of sun and cloud for the region.
Toronto is looking at a forecast high of 5°C and a low of -1°C. These temperatures are regularly seen in March, but are atypical for mid-to-late April.
