Lightning strikes illuminated the skies over the South Coast of British Columbia overnight in a rare spectacle as a severe thunderstorm swept through the area, causing disruptions at Vancouver International Airport and impacting flight operations.
Describing the weather event, CBC meteorologist Johanna Wagstaffe noted the occurrence of numerous cloud-to-ground lightning strikes, predominantly concentrated in the Vancouver and Richmond areas. The storm, originating from a low-pressure system that moved ashore near Richmond after its journey from the equator, was laden with moisture.
The thunderstorm led to chaos at Vancouver International Airport, resulting in multiple delays and cancellations during the period from 9 p.m. on Saturday to 3 a.m. on Sunday. Due to safety concerns related to lightning in the vicinity, departing flights were grounded, and arriving flights faced challenges reaching the gates.
YVR reported ongoing flight disruptions on Sunday as efforts were underway to restore normal operations in collaboration with airlines. Social media videos depicted significant flooding in parts of the airport, reinforcing the need for passengers to verify their flight statuses before heading to the terminal.
In addition to the airport impacts, the storm system triggered a high streamflow advisory for the Central Interior region, encompassing areas like Pemberton and its surrounding watersheds, the Chilcotin River, the Bridge River, and the Cariboo River. Precipitation estimates indicated a range of 20 to 25 millimeters with higher amounts of 30 to 60 millimeters projected in select regions.
A travel advisory for Highway 99 between Pemberton and Lillooet was issued due to heavy rains near Pemberton, warning travelers of potential road closures on short notice. B.C. Hydro reported numerous power outages, affecting over 3,800 customers in the Lower Mainland and Sunshine Coast regions as of Sunday morning.
