Overnight Thunderstorm Disrupts Vancouver Airport Flights

A powerful thunderstorm rolled across British Columbia's South Coast overnight, bringing hundreds of lightning strikes and forcing a multi-hour suspension of flights at Vancouver International Airport (YVR). The storm, described as severe and rare, caused travel chaos and left thousands of residents without power.

From 9:30 p.m. Saturday to 2:55 a.m. Sunday, no departing flights were able to leave YVR due to lightning in the vicinity, according to an airport statement. Arriving aircraft also faced difficulties, with many unable to taxi to their gates after landing, resulting in flight delays and cancellations.

"It is unsafe to operate when there is lightning in the area," the airport said, explaining the suspension. While conditions have improved, some flights were still affected on Sunday as the airport worked with airlines to restore normal operations. Travelers were advised to check their flight status before heading to the airport.

CBC meteorologist Johanna Wagstaffe described the storm as "quite the system," with "hundreds of cloud to ground strikes ... mainly in Vancouver/Richmond." She attributed the event to a low-pressure system that pushed onshore near Richmond after traveling from the equator, carrying abundant moisture.

Environment and Climate Change Canada offered a slightly different meteorological explanation, pointing to an upper-level trough that crossed southern B.C. overnight, bringing unstable conditions that triggered numerous thunderstorms. The agency recorded 22.2 millimetres of precipitation at the airport between 10 and 11 p.m. Saturday.

Beyond the airport, the storm had wider impacts. The B.C. Wildfire Service reported more than 7,000 lightning strikes across the province on Saturday, some of which sparked new fires, though accompanying rainfall helped moderate fire behaviour.

The storm also prompted a high streamflow advisory for the Central Interior, including the Pemberton area, Chilcotin River, Bridge River, and Cariboo River. The B.C. River Forecast Centre anticipated 20 to 25 millimetres of precipitation from the storm, with 30 to 60 millimetres in parts of the Cariboo to the Yellowhead region.

A travel advisory was issued for most of Highway 99 between Pemberton and Lillooet, warning that the road could close on short notice due to heavy rain.

B.C. Hydro reported numerous outages overnight, leaving more than 3,800 customers without power in the Lower Mainland and Sunshine Coast regions as of Sunday morning.

Videos shared on social media showed significant flooding in parts of the airport, and YVR's website listed multiple delays and cancellations on Sunday. The airport activated its terminal response team and brought in additional staff to assist affected passengers.

While the storm has passed, its effects continue to ripple through travel and infrastructure in the region.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
