Mixed precipitation totals of up to 40 mm is forecast to fall throughout the watershed between Thursday afternoon and Friday evening. The bulk of the precipitation is anticipated to fall as rain. While the ground is no longer frozen and the snowpack has melted, infiltration potential is reduced due the seasonally high groundwater table and lower evapotranspiration rates typical of early spring. As a result, water levels are expected to rise and channels are likely to exceed bankfull capacity and access their natural floodplain, should temperatures remain above freezing throughout the storm.
Widespread flooding is not anticipated, however fast flowing water and flooding of low lying areas and natural floodplains may be expected.
Conservation Halton is asking all residents to stay away from watercourses and structures such as bridges, culverts and dams. Elevated water levels, fast flowing water, and slippery conditions along stream banks make these locations extremely dangerous. Please alert children in your care of these imminent dangers.
Conservation Halton will continue to monitor stream flow and weather conditions and will issue further messages as necessary.
This Watershed Conditions Statement will be in effect through April 2nd, 2017.
