Rainfall Warning Issued for Sudbury Region
Sudbury’s weather today is a mix of mild temperatures and heavy precipitation, thanks to a low-pressure system set to arrive this afternoon. A Rainfall Warning is in effect, forecasting 20 to 30 mm of rain combined with melting snow. With the frozen ground struggling to absorb this moisture, there’s a risk of flash flooding and water pooling, especially in low-lying areas.
Currently, Sudbury is at 2°C with mist blanketing the region. The air is saturated with 99% humidity, while the barometric pressure, sitting at 101.4 kPa, is rising slightly. Winds are light from the southwest at 10 km/h, offering little resistance to the damp chill.
