Time Between Wildfire, Storm Season Getting Shorter: BC Hydro Report
BC Hydro says drought can weaken trees without visible signs, leaving power lines more exposed when windstorms and heavy rain arrive.
BC Hydro released a report this month warning that drought-stressed trees significantly increase the risk of winter storm outages across British Columbia. Trees weakened by summer heat and wildfires are more vulnerable to falling into power lines during severe weather.
Emergency seasons are "becoming increasingly connected," according to the report, which notes that storm season now effectively begins in the summer. Spokesperson Whitney Deane said there isn't always a clean break between wildfire and storm seasons anymore.
The Crown has increased annual vegetation management spending to approximately $150 million over six years to remove hazardous trees near power lines. Hydro also replaced 110 transformers while deploying advanced outage prediction tools to identify high-risk areas.
An evacuation order was issued for the Village of Zeballos on Vancouver Island due to a landslide as much of the South Coast faced recent storms. Rainfall forecasts suggest potential for intense atmospheric rivers, compounding risks for already stressed landscapes.
Forecasts suggest extreme climate patterns could bring warmer temperatures and potentially intense storms to British Columbia. Preparedness must now be a year-round effort to mitigate ongoing risks from prolonged drought conditions affecting the region.
