PAGASA Rainfall Warning Signal Modified

The PAGASA Rainfall Warning System (RWS) is in operational mode since its launching on June 20, 2012 but is still open for suggestions to improve it. The initial color coding: YELLOW, GREEN, RED was used based on the color coding scheme of the Community-Based Flood Early Warning System (CBFEWS) under the United Nations Development Program (UNDP) project.

Effective today, the code GREEN of the RWS is changed to ORANGE such that the warning levels are now YELLOW, ORANGE and RED. These colors are generally associated with awareness, preparedness and emergency respectively.

         The color ORANGE was adopted as it is a more appropriate representation of the severity of the situation. This was based on suggestions after our Information Education Campaign (IEC) efforts with the media and discussions with the National Disaster Risk Reduction and Management Council (NDRRMC), Metro Manila Development Authority (MMDA) and Department of Interior and Local Government-National Capital Region (DILG-NCR).

Rainfall Warning Signal of PAGASA started with YELLOW GREEN RED. People are confused with said coloring signal. At the midst of test pilot month people are suggesting to change GREEN Warning to ORANGE warning, because GREEN is said to be GO signal for traffic. Rainfall warning signal was tested versus the Enhance Southwest Monsoon (HABAGAT) due to TY GENER (SAOLA)  People are still confused about the warning specially the GREEN Warning. PAGASA technical working group are on discussion about the suggestion and recommendation of the people.  But before it was finalized here come's the rains brought by the HABAGAT.  Changing or modification of the Color coding that may lead to more confusion the first rainfall warning was used.

For the first month of implementation people are still hoping to change the Color Scheme and on August 9, 2012. GREEN is changed to ORANGE,

"This is to inform the Public that the Code GREEN in the PAGASA Rainfall Warning System is changed to ORANGE effective today, Aug 9, 2012. The rainfall warning levels are now "YELLOW, ORANGE, RED" the colors associated with awareness, preparedness and emergency. DOST-PAGASA"
