I wondered if this was near you, Marianne. It's all over our local news, and I had the impression you were in the Interior, but no idea precisely where. I gather slightly "cooler" (HA!) temps and a shift in the wind have provided a small bit of help today, and I'm praying that the fire fighters can capitalize on that, before the window closes and the temps go up again tomorrow. for your BIL and his neighbourhood and everyone else in harm's way.
I am in the northern interior. My Brother inlaw was able to post on facebook this afternoon. He and his girlfriend are staying with friends. He has no cell service. At least we know he is safe. His neighbour hood was the first to evacuate. He still doesn't know if his house is gone or the business he works at will be there. My friend also has two daughters that live in the subdivision. She knows one is safe, but is unable to get a hold of the other one. I hope they can get this fire under control soon.
