British Columbia’s south coast faces significant challenges as an atmospheric river impacts the region with heavy rainfall. The Ministry of Water, Land, and Resource Stewardship has elevated a flood watch to a flood warning for parts of Metro Vancouver and the Fraser Valley. This advisory indicates that river levels have exceeded their capacities, leading to expected flooding in adjacent areas.
Heavy Rainfall Forecast for South Coast
Environment and Climate Change Canada predicts rainfall amounts between 40 to 70 millimeters from Tuesday to Wednesday evening. The agency cited that warm air associated with the weather system is likely to raise freezing levels, contributing to snowmelt and high streamflows. This could also lead to localized flooding.
Motorists should anticipate water pooling on roads, especially in low-lying areas, where visibility may sharply decline during heavy rain. 1130 NewsRadio Meteorologist Michael Kuss notes that this atmospheric river originates much further back, near the Hawaiian Islands, and will intensify as it moves over Vancouver Island.
Orange Warning in Effect
The heaviest rainfall is expected in eastern Metro Vancouver and extending into the Fraser Valley. An “Orange Warning” has been issued for the central Fraser Valley, including Chilliwack and areas east to Hope, indicating the development of dangerous conditions. This warning signals a high risk of flooding due to saturated ground and ongoing heavy rains.
- Areas Affected: Central Fraser Valley, Chilliwack, Hope, Highway 3 route from Hope to Princeton.
- Hazards: Impassable roads, flooding, and challenging driving conditions.
Localized Flooding in Abbotsford
The City of Abbotsford has reported incidents of localized flooding as of Wednesday morning. Officials are in close contact with counterparts in Whatcom County, Washington, concerned about the Nooksack River’s potential overflow. If the river rises above its banks, it could lead to flooding along Vye, Boundary, and Angus Campbell roads.
To prepare, Abbotsford has established an emergency operations center to monitor river conditions, and staff are stationed at the Barrowtown Pump Station. The city is ready to close roads at vulnerable spots, such as Clayburn Road, which is currently shut between Highway 11 and Wright Street.
Safety Measures and Warnings
Residents are urged to avoid riverbanks and ensure storm drains are clear. The city has made sand and sandbags available at its Public Works Yard for those in need. Meanwhile, BC Highway Patrol has advised motorist safety during this spell of adverse weather.
- Driving Tips:
- Reduce speed in rainy conditions to improve reaction time.
- Beware of pooling water that can affect braking.
- Exercise patience and allow extra time for travel.
As the atmospheric river continues to affect B.C.’s south coast, safety and preparedness remain paramount. Residents are encouraged to stay informed through local media and prepare for evolving conditions.
