Flood warnings raised in B.C. as rainfall tops 200 millimetres northwest of Vancouver
River levels are rising rapidly as more rain is forecast through Thursday, with evacuation alerts and flooding reported in several communities.
Flood warnings have been raised across British Columbia's South Coast after more than 200 millimetres of rain fell in a 24-hour period, prompting the River Forecast Centre to upgrade flood watches to warnings in Pemberton Valley, Howe Sound, Sea-to-Sky and North Shore.
A series of atmospheric river systems have impacted the region since last week, with Environment Canada meteorologist Michael Gismondi stating wet conditions are expected to persist into the weekend.
Environment Canada meteorologist Jennifer Hay reported 214 millimetres of rain in Port Mellon, while the River Forecast Centre noted rivers including the Stawamus and Squamish have been "rising rapidly."
Late Tuesday, the Village of Pemberton issued an evacuation alert for properties on Airport Road due to high river flows, while flooding occurred around One Mile Lake.
Weather models indicate another 100 millimetres of rain through the Sea-to-Sky corridor, leading the British Columbia Transportation Ministry to warn drivers to monitor conditions as river levels continue rising into Thursday.
