Over the last few days, the nearby volcano, Popocatépetl, has been making sure everyone remembers he's not dead, or asleep, or in a coma. He's been fuming and spitting out ash and glowing at night. Yesterday ash started falling on some of the towns in the area and today some of the schools remained closed. The authorities have increased the Alert Level to Yellow Phase 3, which among other things, means that people have to be ready to evacuate if necessary.
Here are some photos of the volcano (taken from newspapers):
