Heavy rain, localized flooding possible for Hamilton and area, says Environment Canada

Hamilton, Niagara, Brantford and surrounding areas could see up to 25 millimetres of rain Tuesday night through Wednesday, according to Environment Canada.

The weather agency issued a special weather statement for the area and warned the frozen ground "has a reduced ability to absorb this rainfall."

"Localized flooding in low-lying areas and water pooling on roads is possible," the agency said. 

The rain could get heavy at times, and come along with "mild temperatures" and a risk of thunderstorms on Wednesday.

Mild temperatures set for Wednesday

The forecast on Tuesday calls for a high of 6 C and a low of 3 C, and a high of 11 C and a low of 2 C on Wednesday. 

Environment Canada recommends people reach out to their local conservation authority or Ministry of Natural Resources office for more information on possible flooding.

The Hamilton Conservation Authority (HCA) said Monday water levels in all watercourses in its area are expected to increase "significantly" due to the rain and snowmelt expected this week. 

"There is potential for significant watercourse flooding, as considerable amounts of runoff may occur given snowpack and soil conditions within the watershed. There is considerable uncertainty as to the amount of runoff that will occur," it said on its website. 

It warned to keep children and pets away from bodies of water this week. 

"HCA wishes to remind residents to exercise caution near all water bodies and structures such as bridges, culverts and dams during this time. Above normal water levels, faster moving water, rapidly changing levels and flows, unsafe ice, and slippery banks may pose significant hazards."
