KRON4 is taking a closer look Thursday night on those North Bay Fires and examining how it was they became so destructive so fast.
Some experts are saying the blazes acted like a hurricane, but instead of water, it was fire swirling around, causing widespread damage.
When the fire hit at Coffey Park, it was whipping around erratically. Officials call it a firewhirl and that whirl was running horizontally, plowing through homes and pushing over cars as if they were toys.
As fire investigators examine how this fire started, KRON4 is learning why it was so violent and vicious, devouring everything in its path.
