Isolated slow moving thunderstorms with very heavy downpours are expected again this afternoon in a warm and humid tropical air mass across much of Southern Ontario.

Local rainfall amounts of 20 to 40 mm in an hour or less along with wind gusts to 70 km/h are expected from some of the stronger thunderstorms. Small hail is possible.

Sudden very low visibility and ponding of water on poorly drained areas of highways from the downpours may result in difficult driving conditions.

The showers and thunderstorms are expected to end this evening.
