September 5th Thunderstorm

Unusually high CAPE (Convective Available Potential Energy) levels were available during the afternoon of September 5th and with the appropriate triggers in place, a large, intense thunderstorm developed from the southeast and stalled over Burnaby, New Westminster, East Vancouver, and Surrey for several hours in the late afternoon. Many cloud-to-ground strikes were observed by the public and for the second time in two weeks, social media was abuzz with the electrifying news.  

At the height of the storm over 6600+ customers were without power, according to BC Hydro and precipitation totals in some of the more intense thunder cells produced over 20mm/hr+ rates of rainfall.
