The BC River Forecast Centre has issued a high streamflow advisory for a wide swath of the province, including areas of the Cariboo-Chilcotin.
Hydrologists say warmer weather over the next several days could see smaller streams and tributaries rise rapidly due to snow melt in the low-to-mid level snowpacks.
Quesnel and areas west, including Baker Creek, and Williams Lake are listed in the advisory.
The river forecast centre says some of the areas were hit hard by the 2017 wildfire which may make the possibility of flooding worse due to lack of vegetation.
Environment Canada is calling for temperatures in the low to mid-20s for most of southern B.C. through Friday, followed by wetter weather in the southeast.
