People in vulnerable areas are recommended to prepare to evacuate. The areas designated are parts of Amakusa, Yatsushiro, Kumamoto City and Mifune. The West Ward (Nishi-ku) of Kumamoto City, Yatsushiro, and Amakusa have coastal areas where evacuations may be needed. I assume that Mifune is a candidate for evacuation because of the possibility of landslides or flooding in some areas. Please try to learn what you can about the vulnerabilities of your particular area and where you can go if you need to evacuate.
