New flood watch, high stream advisories, evacuation alerts as rains swell B.C. rivers
VANCOUVER — Recent heavy rains across British Columbia’s central and southern Interior are swelling river levels in many areas, prompting a renewed flood watch and more high streamflow advisories.
The River Forecast Centre has upgraded the Nechako River system to a flood watch as up to 40 millimetres of rain fell over central B.C. since Tuesday, causing what the centre says are “sharp rises” in water levels near Vanderhoof and west of Prince George.
High streamflow advisories have also been issued for waterways through the Chilcotin region west of Williams Lake and for the upper Columbia River north of Golden where levels are expected to reach a five-year return by Thursday.
The centre is maintaining a flood warning for the Quesnel River east of Williams Lake and flood watches for the Thompson and South Thompson rivers, including Shuswap Lake, as it monitors the effect of the rain in those regions.
