"Several days of high temperatures has led to rapid melt of this season’s snow pack. River levels have been rising quickly in response to this melt," read a release.
"River levels are expected to continue to increase through the remainder of the week, reaching the highest levels late on Friday or into Saturday," the release went on to say.
Clouds and showers and slightly cooler temperatures are forecast for this weekend in Grand Forks and the BC River Forecast Centre said this might cause river levels to decrease slightly on Sunday.
Mainly sunny with a high of 29 C is forecast for Saturday and a high of 27 C, with a 40 per cent chance of showers, is forecast for Sunday according to Environment Canada.
"Environment Canada weather forecast is for the warm weather to hold through Saturday, with a cooling trend starting Sunday with the possibility of showers. Temperatures are expected to be in the low '20s Wednesday through Friday next week," explained Kootenay Boundary Regional Fire Rescue deputy regional fire chief/emergency program co-ordinator Dan Derby in a release.
"The River Forecast Centre provided the Regional District of Kootenay Boundary (RDKB) with the following summary this morning: Entering tail end of snow melt from hot weather, the rate of rise has slowed down and the Kettle and Granby Rivers are expected to pulse five to 10 cm over the weekend with the Kettle at a two-year return level and a possibility of the Granby going to a five-year return level.
"Systems are expected to stay 50 cm below 2006 levels. The high streamflow advisory for the West Kettle, Kettle and Granby Rivers and tributaries will stay in effect 'til Monday. Dependent on what level of participation we receive in the Boundary basin, there may be a possibility of going to a flood advisory early next week."

The Regional District of Kootenay Boundary (RDKB) Emergency Program continues to be activated at Level 1, allowing staff to respond to requests for sandbags from residents RDKB emergency program co-ordinator Dan Derby said last week, adding that RDKB staff will continue to monitor river levels, forecasts and advisories and provide updates.
Derby recommends residents stay away from river banks as well.
"High water levels can push logs and other large debris into the river increasing the danger to people," he said.
