Environment Canada has issued a rainfall warning for the greater Kawarthas region for Sunday (April 30), with Otonabee Conservation also issuing a flood watch for the Trent-Severn Waterway.
The rainfall warning is in effect for Peterborough County, City of Kawartha Lakes, Northumberland County, Haliburton County, and Hastings County.
Periods of rain will persist intermittently Saturday evening before tapering to a chance of showers overnight. Heavier rain is expected to move in Sunday afternoon and by Monday morning, with additional rainfall amounts of 40 to 50 mm expected.
Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts.
Multi-day rainfall totals of 50 to 70 mm could worsen the situation for sensitive areas.
Otonabee Conservation has issued a flood watch for the headwaters of the Kawartha Lakes (Haliburton/Reservoir Lakes region) and the area of the Trent-Severn Waterway under its jurisdiction.
Water levels in the Haliburton/Reservoir Lakes and the Kawartha Lakes are approaching their respective full levels due to the past several weeks of sustained snow melt, ice melt, and rainfall runoff.
The forecasted rainfall will generate saturated ground conditions resulting in direct surface runoff into low-lying areas, wetlands, ditches, and all local watercourses. Swelling rivers, streams, and creeks may result in flooding.
Otonabee Conservation is advising residents and businesses located in flood-prone areas to be vigilant. Otonabee Conservation is also advising residents and visitors to be extremely cautious if travelling on area lakes and rivers.
