Shoreline and flood worries as wind and rain hit Hamilton and region

A flood watch was in effect for Hamilton as the city and much of southern Ontario brace for several more days of rain.

The Hamilton Conservation Authority (HCA) says this forecasted rainfall may result in further increases in water levels and flows in area watercourses, with the potential for significant flooding.

There is further concern about the potential impacts of northerly winds on the shores of Lake Ontario. Those  winds may increase the risk of shoreline flooding and erosion, with Lake Ontario levels already high.

The latest rainfall — from Thursday through to Saturday — comes on top of records numbers for the year so far.

“This has been a record rainy first 125 days of a year, never has there been so much rain in that period in the Hamilton area,” said Dave Phillips, Environment Canada.

Phillips says Hamilton has received about 87 per cent more rain than the city would normally get so far this year.

The potential rainfall may also result in local drainage issues in low-lying or poorly drained areas, and storm sewer systems may become overwhelmed in intense rainfalls over short durations. (CBC News)
