VICTORIA – Canada’s weather agency issued storm warnings and advisories across much of B.C.’s south coast early Friday, indicating that rain and gusty winds will disrupt activities throughout the weekend.

Environment Canada’s rainfall warning for the Lower Mainland extends from Vancouver on the coast to the Fraser Valley, including Abbotsford and Mission.

The warning also covers Howe Sound and sections of the Sea-to-Sky Highway south of Whistler.

“Rain will begin this morning and intensify through the afternoon and evening, with the heaviest rainfall expected Saturday morning and early afternoon,” Environment Canada said in its warning for the Fraser Valley.

“Rain should ease by Saturday evening, although a second wave is expected on Sunday.” Metro Vancouver and the mountainous areas of the Fraser Valley West are expected to receive between 40 to 70 mm of rain.

Higher amounts are anticipated over the North Shore Mountains and along the Sea-to-Sky corridor. Meanwhile, areas around Chilliwack and Hope are under a weather advisory that also calls for rain and wind, although neither is expected to reach the intensity forecasted for areas west of these municipalities.

“Ahead of the storm, ensure that drains are clear of leaves and debris, and secure loose objects outdoors,” said Environment Canada. “Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.”

The BC River Forecast Centre has issued a flood watch for much of the BC coast, including tributaries of the Lower Fraser, such as the Lillooet River and rivers around Pemberton, Metro Vancouver, the Lower Mainland, and the Fraser Valley.
