Actually, listen to local authorities, if you can see the fire then there's a good chance that it's too late. I'm sure you're aware of our newer "stay or go" procedures and that these decisions must often be taken 12-24 hours in advance. You don't want to be one of those tragic images of a burnt out car on the road while you were trying to evacuate.
If OP is asking on HN now then I think it's safe to say they don't have a well thought out evacuation plan and should leave ASAP if it's still safe to do so, just take the phone, wallet and a few clothes.
