River levels have remained elevated due to on-going snowmelt and episodes of precipitation. Some rivers have experienced more rapid rises over the past day in response to rainfall.
A high-pressure system is expected to build through this week, with rising temperatures starting Wednesday and extending for 3-4 days. In areas with some mid-elevation snowpack remaining, rivers levels may see additional rises through the rest of the week; this includes the Bonaparte River, Nicola River, Salmon River, tributaries in the North Thompson River and in the North Okanagan and Shuswap Region. In these regions, flows may exceed levels that have previously been experienced this year. Flows are generally expected to remain in the 2-year to 5-year range, except on the Bonaparte River and Salmon River, where current flows are near 20-year return periods and expected to see additional rises.
As the high-pressure ridge moves out of British Columbia over the weekend, rainfall is possible and may lead to more significant river rises over the weekend or early next week.
The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.
