A high streamflow advisory has been issued by the Ministry of Water, Land, and Resource Stewardship on Aug. 23 for much of south-central B.C.
The River Forecast Centre for the province issued the advisory on Aug. 23 at 1:30 p.m. for parts of the Central Interior, Cariboo, Thompson, Upper Columbia, and Upper Fraser areas.
A high streamflow advisory means river levels are rising or expected to rise rapidly, but that no major flooding is expected. Faster-flowing water may increase risks to life and safety and minor flooding is possible in low-lying areas.
Areas under the advisory include the Central Interior including tributaries around Merritt, Cache Creek, Ashcroft.
In the Cariboo region, the advisory includes the tributaries around Nazko, 100 Mile House, Williams Lake and Quesnel.
For the Thompson Region the tributaries around Kamloops, Clearwater, Valemount, and Salmon Arm are under the advisory.
In the Upper Columbia they include tributaries around Revelstoke and Golden and in areas of the Upper Fraser the tributaries tributaries around McBride may also see rapid water level increases.
With a low-pressure system moving through large parts of the province, heavy rainfall was expected in many areas, starting on Friday with rainfall in some places 15 to 40 mm.
Rapid rises in rivers were forecast to begin on Saturday and continuing into Sunday, with smaller rivers more susceptible to large increases in water level.
"Current hydrologic modelling is indicating the potential for flows in the two-year to five-year return period level in areas," stated the release from the centre.
Wildfire impacts in areas may mean higher water level fluctuations in some areas.
