The capital is under a severe thunderstorm warning as Environment Canada tracks a major storm southwest of Ottawa.
The storm is moving east at 60 km/h from the Mississippi Mills area and could impact Kanata, Almonte, South March, Stittsville, Hazeldean and Shirleys Bay.
Environment Canada issued the warning shortly before 3:25 p.m. and says gusts could reach 90 km/h and could produce tornadoes.
A severe thunderstorm warning is issued when a storm is occuring or imminent, while watches are issued when conditions are favourable for the development of thunderstorms. A severe thunderstorm watch was issued in Ottawa on Sunday morning.
The capital continues to be under a rainfall warning, where 40 to 60 millimetres of rain are expected this weekend. Approximately 22 mm of rain fell on Ottawa as of 2:30 p.m. On Saturday, Ottawa received 3.2 mm of rain.
“A low pressure system will continue to bring significant rainfall to the region through this afternoon. Areas that receive multiple thunderstorms may have the potential to exceed 60 mm locally,” Environment Canada said. “Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.”
