A small plane crashed into a San Diego neighborhood during foggy weather early Thursday, setting about 15 homes on fire as well as vehicles. As of 7 a.m. this morning, this is the area authorities have identified as affected by the crash.

Dense fog had rolled into the area around the time the plane was approaching the airport. Visibility was at half a mile at 3:55 a.m. and had dropped to a quarter of a mile just after 4 a.m. in the area around Marine Corps Air Station Miramar, which is just a few miles north of the crash site, according to the National Weather Service.
