Overview
- Environment Canada continues snow squall warnings for Greater Sudbury as intense bursts reduce visibility to near zero.
- Local snowfall of 10–20 centimetres is possible, with the highest totals expected on Manitoulin Island and in areas south of Highway 17.
- Lake-effect snow from relatively warmer lake waters is creating narrow, fast-moving bands that produce rapid changes over short distances.
- Forecasters say conditions should gradually improve as the bands shift south later tonight or into Monday evening.
- Motorists are urged to slow down, leave extra space, monitor Environment Canada alerts, and share severe weather reports via ONstorm or #ONStorm.
