Have you ever received an emergency alert from the National Disaster Risk Reduction and Management Council (NDRRMC) with loud phone alarm?

If so, you may have noticed the color-coded rainfall advisory in the message.

Why do these alerts exist, and how do authorities determine the rainfall warning color for a specific area?

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), there is a three-color rain warning system used to identify rain intensity and guide communities.

The Yellow Level Advisory is issued for rainfall amounts of 50 mm to 100 mm. At this level, flooding is possible in urbanized, low-lying, or near-river areas.

Next is the Orange Level Advisory with rainfall amounts of 100 to 200 mm. Flooding is expected in several areas, and landslides are possible in highly susceptible areas.

The Red Level Advisory applies to heavy rainfall exceeding 200 mm. Under this alert, widespread flooding and landslides are expected, requiring immediate emergency response.

Understanding these color-coded warnings allows households to stay informed and safe. Help keep your friends and family safe by sharing this information, so they know what to do when the next emergency alarm goes off.
