Several schools were closed. More than 500 firefighters were on the scene. The Los Angeles County Fire Department moved in the area seven engines and three helicopters to the fire. Later, two fire fighting water-dropping Super Scooper planes were added. The town was covered in ash and a big cloud of smoke dominates the area.
The wildfire is very dangerous because California is in a historically dry era. The latest big fire in the San Gabriel Mountains, in 2009, burned for months and produced a big damage. Notorious winds manifest in the region and make the situation even more difficult.
Three people were arrested by Glendora police in connection with the fire. The cause of the fire is still under investigation. Chris Jeffers, the city manager of Glendora, declared a state of emergency.
