It is issued when the risk of disasters such as heavy rain, floods, strong winds, lightning, storm surges, and landslides increases, serving as a basis for decisions regarding evacuation and work suspension. Specifically, it includes warnings and advisories such as "Heavy Rain Special Warning," "Landslide Warning," and "Storm Surge Advisory."
