In areas throughout the region, river levels have been high due to snowmelt, and in watersheds with snow remaining warm temperatures the past few days has accelerated snowmelt rates. Yesterday, active convection brought intense rainfall across parts of the region, with the most intense cells of precipitation falling in areas in the headwaters of the Similkameen River including the Ashnola and through Manning Park, Nicola River and areas around Merritt, and areas in the North Thompson River watershed. Lower amounts of precipitation were observed in the Okanagan Valley and Shuswap and South Thompson watersheds. Rainfall amounts were generally in the 5-25 mm range, with areas of most intense rain reaching upwards of 30-40mm.
Additional rainfall is expected today, however the most intense forecast rainfall patterns are forecasted to occur further east of the Central Region. Additional rainfall amounts for the remainder of Sunday are forecast to be in the 5-20 mm range.
The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.
The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.
