Environment Canada is advising the public to be extra vigilant in and around rivers, creeks and culverts after a Special Weather Statement was issued for Arrow/Slocan Lake, Boundary and West Kootenay regions.

The Special Weather Statement comes after warmer conditions during the past few days due to a ridge of high pressure produced rapid snow melt.

The sunny weather saw water levels to rise causing localized flooding in some areas.

“The ridge is moving eastward, and a Pacific system brought 5 to 10 mm of rain to the Southwest Interior (Tuesday) night,” the Statement said. “This area of rain is over the western Kootenay and Arrow Slocan Lakes regions early this morning. General rainfall amounts of 15 to 25 mm are forecast with this system which will add to already full basins resulting in more flooding.”

Environment Canada said rain will taper off in behind this system but showers and the odd thunderstorm will linger giving the potential for localized amounts up to 15 mm.

Meanwhile lesser amounts of 10 to as much as 15 mm are expected through the Similkameen, Nicola and Arrow Slocan Lakes regions but this could still overwhelm some watersheds already at capacity.

The BC River Forecast Centre issues streamflow advisories and warnings when necessary to provide alerts to potential flood conditions in the stream systems of the province.

The public is advised to refer to the River Forecast Centre for updated streamflow advisories or warnings.

The forecast for Wednesday is for rain ending near midnight then cloudy with a risk of thunderstorms this evening.

Thursday, there’s a 60 percent chance of showers in the afternoon with warmer weather returning by the weekend.
