 People need to know when they're going to leave. You can't rely on a warning. And if you wait too long, it could be too late. You're putting not only yourself at risk but potentially your family. Many people have been called out by trying to outrun the fire and that's not a good idea. If you see smoke, it's too late. You need to understand when you're going to go and make the decision. You may not be able to see where you're going. You may have a tree blocking your way. You won't be able to get out. You're putting lives at risk. Now if you don't think your house is safe enough to defend, you'd want to leave as early as you can. If you're into your minds, you should go and enact your plan.
