The Upper Fraser River (through Prince George) is expected to peak this afternoon, and begin receding later today and into tomorrow.
Additional rainfall is possible for the region into the weekend, however there is some uncertainty at this time as to the location and amount of rain that is expected locally. If additional heavy rain is forecast to fall in the region, additional rises in river levels may occur.
The River Forecast Centre will continue to monitor conditions and will provide updates as conditions warrant.
A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.
A Flood Watch means that river levels are rising and will approach or may exceed bankfull. Flooding of areas adjacent to affected rivers may occur.
A Flood Warning means that river levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
