No stopping it.
And with that said the only thing left to do is watch and hope it stops spreading, fight where you see options, and evacuate as many people as you can..
It's traumatic and dramatic. My full thoughts and prayers are with the people there.. It's just horrendous.
There is one site have been following with updated live info as it develops from Canada.. Bookmark it for the near future as this disaster continues..
