Pretty sure the big one in Washington was caused by lightening. Curiously, it was after obama was elected and he caused the sea-levels to fall. Falling sea levels and worse wild fires, probably a one-to-one relationship.
You’re correct, it was started by lightening. We’ve had a beautiful summer so far - -a few days over 80 (which we usually don’t get until Aug)in the Seattle area and not much rain. East of the mountains and Eastern WA is usually warmer.
I heard on the radio last night that they may get rain over the fire area today. Which on one hand is a blessing, though they were concerned if there was a lot of rain there could be flooding as apparently the fire causes the ground to get hard so the water doesn’t sink in easily. They indicated there could be more lightening, too.
