Omen. Smoke billowing. To what?

Smoke billowing could indicate a potential fire. Depending on the context, it could be a controlled burn, a wildfire, or a structure fire. If the smoke is coming from a building or structure, it could indicate a structure fire, which is a serious emergency. In this case, it is important to call 911 immediately and evacuate the area. If the smoke is coming from a large area outside a building, such as a field or forest, it could be a controlled burn or a wildfire. In this case, it is important to contact the local fire department to determine the cause of the smoke and whether or not it is a controlled burn. It is also important to evacuate the area if necessary.
