High flow advisory issued for British Columbia rivers submerged by November flooding

A high flow advisory has been issued by the River Forecast Center for some of the same rivers in British Columbia where flooding last November ripped up roads and devastated communities.

The center says snowmelt over the North Thompson River in central British Columbia will send a “pulse” of water downstream towards the Fraser River.

It says that although the water level is expected to rise, no significant rain or heat is expected, which would cause a significant increase in flow in the river.

Last week’s rain is still moving through the reservoirs, prompting a high flow advisory for the Nicola River, the same river that flooded last November, washing away large sections of Highway 8 and shutting down communities.

The center says that although long-term water monitoring sites were destroyed on the river during historic flooding last November, it is likely that the water pulsation will increase flows downstream.

However, significant rainfall is not currently forecast for the region.

The center advises the public to stay away from fast flowing rivers and potentially unstable banks during the high flow period.

A provincial state of emergency was declared last fall after storms washed out highways and flooded communities in the interior and Fraser Valley.

Five people were killed when caught in mudslides.
