Pineapple Express Brings Heavy Rain to Southern B.C. – What You Need to Know
Southern British Columbia is bracing for another wave of heavy rain, courtesy of a weather phenomenon known as the "Pineapple Express." This powerful system is expected to impact the coastline, bringing substantial rainfall from Friday into the weekend. Areas like Vancouver Island, especially the western communities, will be hit hardest with rainfall totals reaching 100 to 120 millimeters in some places. This sudden downpour could lead to localized flooding, posing significant travel disruptions.
If you’re planning to head out this weekend, especially with thousands of Taylor Swift fans in Vancouver for her 2024 Eras Tour, you might want to adjust your travel plans. The heavy rain is expected to start late Friday morning, continuing into the evening and peaking after midnight. According to Environment Canada, the intense rainfall could cause flash flooding, especially where drainage systems are blocked. It’s essential to be cautious on the roads during this period. If you’re driving in these areas, reduce your speed and be ready for reduced visibility. Watch for water pooling on roads, and be on the lookout for washouts, particularly near rivers, creeks, and culverts.

This "Pineapple Express" is a type of atmospheric river, a narrow band of tropical moisture that extends from the Pacific towards the coast, bringing warm, heavy rain. It gets its name from its origins near Hawaii, where the moisture is sourced. While the rain will taper off after midnight, the danger persists with the possibility of flash floods. Some areas like Port Renfrew, Sooke, and Tofino could see up to 120 millimeters of rain, which could severely affect travel conditions, especially in the more rural regions.
For those planning outdoor activities or skiing trips in B.C., be aware that the rain will cause snow levels to drop significantly. While the mountain areas may initially see rain, snow is expected to return in the coming days, with temperatures dropping below 1000 meters by Saturday. This change could impact ski resorts and other outdoor activities across the region, so be prepared for winter-like conditions as the storm progresses.
In addition to these rain-related issues, fog has been causing flight cancellations at Vancouver International Airport as crowds gather for the Taylor Swift concert. With this combination of rain, fog, and heavy traffic, it’s wise to keep an eye on the forecast for any updates before heading out.
While the rainstorm will end by early Saturday morning, don’t expect clear skies just yet. After a brief period of fair weather, B.C. could face another round of significant weather next week. Mid-December looks to bring colder temperatures, which may lead to beneficial snowfall for the ski areas.
Stay safe, stay updated with the latest weather advisories, and plan accordingly if you’re heading out this weekend in southern B.C.
