VANCOUVER — Flood warnings have been raised in British Columbia’s South Coast, where the province’s River Forecast Centre says up to 150 millimetres of rain has fallen since yesterday amid a series of storms that have been battering the region.

The centre has upgraded flood watches to warnings in the Pemberton Valley, as well as Howe Sound, Sea to Sky and North Shore of Metro Vancouver, while saying the heaviest rain was recorded on parts of Vancouver Island.

Up to 120 millimetres has fallen elsewhere on the South Coast since Tuesday.

While parts of the province including Metro Vancouver were experiencing a morning lull in the storms that have been sweeping across the region since last week, the centre says more rain is forecast throughout Wednesday, with weather models indicating another 100 millimetres through the Sea-to-Sky corridor, and up to 100 millimetres through west and central Vancouver Island.

It’s part of a series of atmospheric river systems that have been hitting the coast, and Environment Canada meteorologist Michael Gismondi says the wet conditions are expected to persist into the weekend.

The River Forecast Centre says rivers in the South Coast region have bee “rising rapidly,” with the Stawamus, Clowhom, and Squamish rivers and Tofino Creek all exhibiting high flow rates.

Orange rainfall warnings that were raised by Environment Canada on Monday remain in place for Howe Sound and the Sea to Sky regions.

The weather office warns residents of central B.C. that the “strong and slow-moving” system is bringing damaging winds, with gusts reaching around 100 kilometres an hour in some areas, before easing tonight.

It says utility outages are likely and driving may be difficult as there is risk of injury due to falling debris.

The River Forecast Centre says in its warning that people should continue to stay away from river banks as the fast flow of water increases the risk of bank instability.

“Continued rises in river levels are expected into Thursday in response to additional rainfall,” the warning says.

B.C.’s Transportation Ministry is urging drivers to monitor conditions and prepare for high winds, heavy rainfall and possible flooding in southern coastal regions for the rest of the week.
