Highlights:

• Temperatures above freezing and rainfall amounts of 15 to 25 mm predicted over the next 24 hrs.
• Rain and melting snow could lead to localized drainage issues.
• Local watercourses will rise and some could reach bank full conditions or spill their banks.
• High lake levels could aggravate drainage issues in shoreline areas.

Message:

Forecasts are calling for rainfall totals between 15 and 25 mm over the next 24 hrs. Last week the region received around 15 mm of precipitation in the form of snow, much of which is still around waiting to melt. Temperatures are also expected to remain above freezing into Sunday.

A significant amount of rainfall in expected over the next 24 hrs. The warm temperatures and rain will also melt most of the snow lying around on the ground. This could lead to ponding and localized flooding in areas with poor drainage. Local ditches, creeks and streams will begin to rise later today and some could reach bank full conditions or spill their banks. The predicted rainfall combined with melting snow is likely to produce enough runoff that the McGregor Creek Diversion Channel will need to be operated.

The rain in the forecast could have a greater impact in shoreline areas. Due to the high lake levels, rainwater is not draining properly from these areas. In addition, any water from upstream making its way downstream on local watercourses into these shoreline areas could further impact these areas.

In order to reduce nuisance flooding, residents should ensure that catch basins and other drainage areas are clear of ice and debris.

People should take extra caution and avoid the river, ditches, and streams. The combination of slippery banks and fast moving cold water can be dangerous. Standing water can also present unseen hazards. Children and animals should be kept away from the water.

Officials will continue to monitor the situation and update this advisory if necessary.
