Environment Canada is warning residents in the B.C. central interior about the possibility of heavy rainfalls over the next few days.
The Prince George, Cariboo and 100 Mile House areas could receive between 20 and 40 mm of rain between Tuesday evening and Thursday, with higher rain over the mountains.
"However, there remains some uncertainty about just how much rain will fall during this prolonged event," the Environment Canada statement said. "In addition to the widespread synoptic rain, thunderstorms will have the potential of adding 15-25 mm over short periods."
A low-pressure system developing over southern Alberta will intensify as it move north into northern Alberta by Wednesday evening. The system is expected to funnel rain into the B.C. central interior.
Moderate rain in the Quesnel River, North Thompson and South Thompson watersheds could result in high water levels on those rivers, Environment Canada warned.
"Rainfall warnings may be issued as the system further develops and confidence in rainfall amounts increases," the statement said.
