More unsettled conditions this afternoon with scattered thunderstorms producing small hail and gusty winds.

Yet another disturbance will sweep across Southern Ontario today into tonight. Scattered thunderstorms are beginning to develop in regions to the east of Lake Huron and south of Georgian Bay down to the Golden Horseshoe. They will spread across Eastern Ontario this afternoon.

Many of the thunderstorms are expected to produce pea-sized hail. The odd thunderstorm may give somewhat larger hail of 1 centimetre or perhaps a little larger. Given the cool temperatures and favourable atmospheric conditions, the hail may be abundant and nearly cover the ground at times. The main concern is damage to tender crops and plants.

Isolated wind gusts to 70 km/h are also likely.

FLOOD POTENTIAL: Moderate – Nottawasaga Valley Conservation Authority

Weather Conditions
5-10 mm of rain was forecasted for Monday.

Flows at most gauges in our watershed have peaked and begun to decline, however, flows will remain elevated for several days as the flood wave moves downstream.

Water levels are expected to slowly decline and no additional flooding is anticipated at this time. However, stream banks may be unstable, which combined with the fast-flowing water can create hazardous conditions.

Please exercise caution around all rivers and streams. Hazardous conditions may exist around all waterbodies, as there is a high risk of life-threatening injury if a person falls into the fast-flowing water.

The Nottawasaga Valley Conservation Authority continues to monitor river and stream conditions and will issue additional messages as conditions warrant.

This Flood Outlook Statement will be in effect until 4:30 p.m., Tuesday June 27, 2017.
