More adverse weather on Vancouver Island is already having an impact and the worst is still to come Friday. BC Ferries has cancelled sailings on its major routes, with the 11 a.m., 12 p.m. and 1 p.m. sailings from Swartz Bay to Tsawwassen, and the 11 a.m., 1 p.m. and 2 p.m. departures from Vancouver. The 10:40 a.m. departing Horseshoe Bay and the 1 p.m. leaving Departure Bay in Nanaimo are cancelled. The 10:15 a.m. and 12:45 p.m. sailings for the Duke Point and Tsawwassen route are cancelled in both directions. BC Ferries cancelled morning sailings between Comox and Powell River because of high winds, which also cancelled sailings between Campbell River and Quadra Island. BC Ferries says service to that route has resumed. Environment Canada has a wind advisory in effect for much of the Island, saying another intense low-pressure system is bringing with it southeast winds of 80 kilometres-per-hour wind gusts of up to 100 km/h for the west Island region. Although the weather office says the wind will ease off by Friday night, another Pacific system is on its way and will produce very strong southeast winds again Saturday afternoon. Greater Victoria and the southern Gulf Islands are also expected to get wind gusts of up to 90 km/h starting Friday afternoon and after a brief break overnight, strong winds are expected to return Saturday. Inland and east Vancouver Island are also under a wind advisory, with winds of 70 km/h and gusts of 90 km/h predicted to come in the evening. Environment Canada says the strong winds could cause damage to buildings and blow loose items around. The strong wind is also being accompanied by heavy rain for west Vancouver Island, with an anticipated 50-to-70 millimetres of rain Friday. Inland regions are forecast to receive 30 to 40 mm, and up to 60 mm in Gold River. Rainfall amounts are expected to be 15 to 25 mm in the Comox Valley.
