Environment Canada has issued a rainfall warning for the northern Kawarthas region for Saturday (June 22) into Sunday morning.
The rainfall warning is in effect for Haliburton County and Hastings Highlands.
Rain, at times heavy, is expected as a low pressure system brings significant rainfall to the region on the weekend.
Rainfall amounts of 50 to 80 mm are being forecast.
Areas that receive multiple thunderstorms may have the potential to exceed 80 mm locally.
Heavy downpours can cause flash floods and water pooling on roads. Watch for possible washouts near rivers, creeks and culverts.
