• Mild temperatures in the forecast for the next few days with daytime highs up to 10 C and up 10 mm of rain.
• Water levels on local watercourses may rise but general flooding is not predicted over the next few days.
• Possible localized flooding in areas with poor drainage or on local watercourses from ice and snow blockages
Temperatures are expected to rise above freezing overnight and daytime highs on Saturday and Sunday are forecasted to be between 5 and 10 Celcius. Forecasts are also calling for up to 10 mm of rain over the weekend. Cooler temperatures are predicted for next week.
Much of the snow in the west of the watershed has already melted and weather conditions over the weekend will cause most of the remaining snow to melt. In the east of the watershed, the snow will continue to melt and some runoff will occur. Some of the smaller local watercourses have already risen in response to the warm temperatures and snowmelt over the last few days. Generally, flooding is not expected over the next few days. However, localized flooding may occur in areas with poor drainage or along smaller local watercourses blocked with ice and snow.
Earlier this week, ice thickness on the Thames River was measured to be between 13 and 25 cm through the downstream areas where ice jamming typically occurs. Flows are not expected to rise high enough over the next few days to cause breakup of the river ice. However, the warm weather and rain will weaken the ice.
People should take extra caution and avoid the river, creeks, ditches and streams. Around open watercourses, the combination of slippery banks and fast moving cold water can be dangerous. On the Thames River, slippery conditions and weakening ice can also be dangerous. Children and animals should be kept away from watercourses.
Officials will continue to monitor the situation and update this advisory if necessary.
This message will be in effect until March 2nd, 2021.
