Highlights:

• Snow melt from warm temperatures
• 25– 35 mm of precipitation
• Water levels to rise and river ice to deteriorate

Short term:

Precipitation forecasts are calling for 25 – 35 mm of rainfall, beginning Thursday afternoon into Friday. Temperatures are forecast to remain well above normal reaching daytime highs of 6º C on Thursday and 4º C on Friday. A significant portion of the rain will be absorbed by the existing snow pack, however continued warm temperatures on Thursday and Friday will melt a good portion of the snowpack

The existing snowpack was measured to be equivalent to near 70 mm (2.7 inches) of water in the northern portions of the watershed and 50 mm (2 inches) of water in southern portions. Ice conditions on the lower reaches of Sydenham remain stable with thickness ranging from 16 – 20 inches.

Water levels on the Sydenham River and all watercourses across the region will begin rising early Friday as a result of above normal temperatures and snow melt. With the precipitation forecast, water levels are expected to be contained within the river banks. Ice conditions are expected to continue to deteriorate this weekend. Increased flows and warmer water will reduce ice thickness and ice cover.

Municipal officials and road superintendents should monitor local conditions.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

Residents are reminded to avoid watercourses and flooded areas due to slippery banks, cold and swift moving water and deteriorating ice. Parents in particular are urged to keep their children away from floodplain areas.

The St. Clair Region Conservation Authority will monitor the flood condition of the watersheds in the region and will provide warnings to municipal officials and media in the event conditions develop which could result in the potential of flooding.
