Flood Alert Level Guide & Online Resources for Monitoring Marikina River & Floods

Marikina City has a four-stage alarm level system for the Marikina River:

• Alarm Level 1, when the water is 15 meters above sea level, means "warning" (babala)
• Alarm Level 2, when the water is 16 meters above sea level, means "prepare" (maghanda)
• Alarm Level 3, when the water is 17 meters above sea level, means "evacuate" (lumikas)

These alarm levels are based on the depth of water in Marikina River (Sto. Nino). Malanday, Nangka and Tumana are considered critical areas.
