Environment Canada has issued a rainfall warning for Northumberland County and is forecasting heavy rain for the southern Kawarthas region for Tuesday night (September 24) into Wednesday.
In addition to the rainfall warning, a special weather statement is in effect for Peterborough County and Kawartha Lakes.
A moisture-laden system is expected to move into the region Tuesday afternoon bringing showers. The showers are expected to become more widespread and heavy at times in the evening, along with the risk for thunderstorms as a more unstable air mass moves in.
Showers will continue into Wednesday morning but are expected to become more isolated and ease off in intensity.
While there still remains a high degree of uncertainty on where the heaviest rain will occur, total local rainfall amounts near 50 mm are forecast for Northumberland County with 30 to 45 mm in Peterborough County and Kawartha Lakes.
Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.
