Knowing when to mobilize a restoration effort – as well as knowing when to avoid premature de-mobilization – is a real challenge in many situations. Some storms, such as misty ice storms, can continue for days with damage continuing to build until you hit a tipping point and a lot trees and wires come down.
Although we all want to start the restoration effort as soon as possible, it is critical to wait until the storm completely passes – i.e., when the wind / rain / snow finally stops. It’s a safety issue. Large amounts of rain tend to weaken tree roots, and if there is a strong wind in one direction for a long period of time that suddenly changes direction as the main part of storm passes, then the trees can more easily be blown over and take the electrical lines with it!
