An intense low-pressure system developing in the south-central United States will move towards the region later today. Heavy rain will begin overnight tonight, changing to freezing rain over the course of the day on Saturday. Stream flows are expected to peak on most of the smaller to medium-sized watersheds on Sunday, and Monday afternoon on the larger rivers.
While significant flooding is not expected, watercourses could reach or exceed bank-full conditions, with minor flooding in low-lying areas. Municipal staff should monitor problem areas and prepare to close low-lying roads.
There is still considerable uncertainty whether most of the precipitation will fall as liquid or freezing rain, however, sustained warmer air temperatures will result in more liquid precipitation, increasing the possibility of significant flooding.
Residents are reminded to stay away from all watercourses. The cold water, combined with slippery and unstable stream banks, will create hazardous conditions near all waterways.
This message will remain in effect until 11:00 am on Tuesday, January 14th, 2020, unless local conditions warrant further updates. Saugeen Valley Conservation Authority (SVCA) will continue to monitor watershed conditions.
