Significant storms battered B.C.’s South Coast heading into the weekend, and forecasters say another batch will bring heavy rainfall and wind this week.
Environment and Climate Change Canada issued a special weather statement Sunday afternoon detailing forecasted conditions for B.C.’s North, Central, and South coasts, as well as Vancouver Island.
They expect significant rainfall to come with these storms starting on Tuesday and running through Thursday, especially at higher elevations.
“A strong and potent series of storms will approach the B.C. coast this week, bringing a prolonged period of heavy rainfall,” Environment Canada said in the update.
“This rainfall event comes on the heels of several low-pressure systems that have moved through the region in recent days, already bringing substantial amounts of precipitation to parts of the coast.”
The weather agency said exact rainfall amounts and specific area coverage aren’t yet clear, but it will issue warnings as the situation becomes clearer.
Expected rainfall combined with accumulated water from the weekend’s storms could lead to pooling, especially in areas with (poor) drainage, and potential flooding, Environment Canada warns.
“Communities with historically lower drainage capacity, as well as areas that have already received significant rainfall should be particularly vigilant,” the update reads. “Take a moment to ensure that your storm drains are clear of leaves and debris.”
No flood warnings are in place, but the B.C. River Forecast Centre has a high streamflow advisory active on the province’s South and Central coasts, the Pemberton and Fraser valleys and Vancouver Island.
These advisories mean that “river levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible,” the River Forecast Centre explained.
Residents have been asked to keep away from unstable banks and swift-running rivers.
