On Saturday, the provincial River Forecast Centre issued a High Streamflow Advisory for the Kettle and Boundary regions of southern B.C.
The region is seeing some of its highest temperatures so far this year, which is triggering rapid snowmelt.
Instruments have recorded daily snowmelt equivalent to up to 30 mm per day for the past two days. As a result, the Kettle River near Westbridge has risen 35 cm since Saturday, while the Grandby River near Grand Forks has risen 30 cm since Saturday.
A low pressure system is expected to bring an additional 20 to 30 mm of rain to the area on Tuesday and Wednesday.
High Streamflow Advisories mean water is moving quickly and may flood low-lying areas.
Northern British Columbia and the Interior have also been dealing with high water concerns. High Streamflow Advisories are still in place for the Bella Coola, Nechako and Quesnel Rivers.
Last week, the Town of Smithers declared a state of emergency and evacuated several neighbourhoods.
One house had to be torn down as it was in imminent danger of falling down the heavily eroded bank of the Bulkley River. The home's contents were moved into storage and the owner is being looked after by the town.
The cooler trend is expected to continue for parts of the north and central coast.
The B.C. River Forecast Centre provides regular updates on the flood situation provincewide.
