> As in, if how many times do you see any flying debris during these winds.
As in: trees falling over onto power lines and limbs falling onto powerlines due to high wind?
All the time. Like the 2007 Witch fire.

In addition to the costs of fighting the fire, the Witch–Poomacha Fire is estimated to have caused an estimated $1.3 billion in insured damages,[1] with the original Witch Fire causing over $1.142 billion in insured damages alone.[14][15]
The California Public Utilities Commission ruled that in the Rice fire, San Diego Gas and Electric had not trimmed back trees as state law requires. It was also at fault, the commission said, in the Witch and Guejito fires. The power line that caused the Witch fires shorted three times in three hours, but the utility didn't cut power to it for six hours.[34]
