The northeastern corner of the province (in red) including the Liard River is now under a Flood Warning. The warning was issued Tuesday afternoon by the River Forecast Centre.

BC's River Forecast Centre has upgraded its Flood Watch on the Liard River to a Flood Warning.

Like the watch, the warning covers the entire river including its tributaries around Fort Nelson and Highway 97 towards Watson Lake.

In a statement Tuesday afternoon, the centre said the river's Upper Crossing automated station was recording flows at 2750 cubic metres per second or a 10-year average; the levels, however, are on the rise.

“On-going rises are expected from snow melt and rainfall runoff. Extremely high flows, exceeding 50-year return period levels or similar to flood conditions in 2021, are possible later this week or early next week,” warned the statement.

“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.”

The forecast for the Fort Nelson region is calling for thunderstorms on Wednesday beginning near noon with 5-10 millimetres of rain and up to 20 mm of precipitation near the storms.

The unsettled conditions are expected to continue with the same amounts forecast into Wednesday night.

Below is the full two-day forecast:

Tuesday night: Partly cloudy with 40 percent chance of showers. Risk of a thunderstorm in the evening. Low 11.

Wednesday: A mix of sun and cloud with 30 percent chance of showers in the morning. A few showers with thunderstorms beginning near noon. Risk of hail in the afternoon.
