A warning has been issued for coastal flooding along B.C.’s South Coast this weekend, affecting Metro Vancouver and parts of southern Vancouver Island. Environment Canada announced the alert on Thursday, citing high tides and low pressure that may lead to minor to moderate coastal flooding. The City of Vancouver anticipates the highest coastal water levels in four years.
The South Coast is experiencing high astronomical tides due to the Earth’s proximity to the Sun (perihelion) coinciding with a low-pressure system passing through the region. This atmospheric pressure drop is expected to elevate coastal water levels beyond normal tides, increasing the risk of flooding. The agency highlights Sunday as the peak risk day, although the exact timing of the low-pressure center remains uncertain.
Potential locally significant flooding is foreseen, with roads and walkways possibly becoming impassable due to flooding or debris. The City of Vancouver warns that areas along the Fraser River, Burrard Inlet (including English Bay), and adjacent low-lying regions could be impacted. Water levels are projected to peak around 7:30 a.m. PT on Sunday, with neighborhoods such as Southlands, the South Vancouver Industrial Area, and Locarno Beach facing heightened flood risks.
Vancouver’s Seawall will remain open, with authorities conducting inspections on tide gates and utilizing drones to assess the Southlands shoreline dike condition. In response to heavy rainfall and colder temperatures, additional shelter spaces will be made available by the city. Residents and businesses in low-lying areas are advised to monitor heavy rainfall and pooling water, avoid affected shorelines, and refrain from entering floodwaters.
Avalanche Canada has issued warnings for potentially hazardous conditions over the weekend in alpine regions of Vancouver’s North Shore mountains, the Gibsons area, and areas east of Prince George. The risk of avalanches is considerable in various regions, prompting the agency to advise against traveling to avalanche-prone areas to ensure safety.
