The BC River Forecast Centre said a mix of warm and showery conditions in northern B.C. and the Yukon is driving increased runoff into local waterways.
The Liard River watershed is now nearing the peak of its freshet season, the time of year when melting snow leads to rising river and stream levels.
“This pattern is expected to continue through Friday, followed by steadier increases in temperatures over the weekend and into early next week,” the centre said.
Officials are reminding residents that fast-moving rivers at this time of year can be dangerous, with unstable ground conditions near riverbanks adding to the risk.
They are urging people to stay away from rivers and to avoid entering flood-prone areas.
“Never drive through floodwaters, as unseen hazards and currents can be life-threatening,” they added.
The advisory was issued shortly after 10 a.m. Thursday. Environment Canada is also forecasting a high likelihood of showers and possible thunderstorms through Friday.
River levels in the region have been steadily climbing over the past several weeks, and officials say they could continue to rise into next week as snowmelt conditions persist.
