If your son is in a warm building in the Bham area and he is safe, he needs to stay there.

From what I'm seeing on tv, most of the roads are blocked with traffic. Low tire pressure increases traction, but that won't keep you safe if you can't get thru the blocked traffic.

My granddaughter is stranded at Hueytown Middle School and Hueytown won't let me thru their streets to get to her in my 4x4 vehicles, so she's going to be under the care of the people at her school for now. My daughter and her husband are both stranded at work across town, and I told them to stay put there where they are safe and warm.

Emergency vehicles are having trouble getting to hospitals , and you are putting yourself in danger if you attempt to go thru town right now. Don't do it.
