What do Yellow, Orange, and Red rainfall warning signals mean? It was a laudable effort on the part of PAGASA back in 2012 to use color codes to simplify its Rainfall Warning System. However I instantly got confused and wondered why they initially used a “Green Warning” to refer to the middle warning level when, in most cases, “green” is associated with nature and symbolizes calmness.
